Types of bite

The bite is the relationship between the teeth of the upper and lower jaws when they are closed. Depending on the nature of the closure, the types of bite are distinguished. It can be right and wrong. Doctors also talk about physiological and pathological occlusion. For example, if the jaw is too forward, so that individual teeth protrude and stick out, then correction is necessary.

An orthodontist deals with bite problems in children and adults. You can determine a malocclusion yourself. In front of the mirror, you can notice that the closure of the teeth is not ideal. In addition to aesthetic defects, malocclusion is also fraught with disturbances in facial expressions and speech. Facial asymmetry is often observed, which causes psychological problems to arise.

What is correct (physiological) bite

Physiological types of occlusion are characterized by the correct closure (occlusion) of the teeth. There should be no gaps, gaps or bony protrusions between the teeth. Correct occlusion is established only when all teeth are located along the center line.

Correct types of occlusion do not involve disturbances in chewing function. The upper jaw is shaped like a semi-oval, and the lower jaw resembles a parabola.

A physiological bite gives a person the following advantages:

aesthetic smile;
correct articulation and clear speech;
correct primary processing of food (chewing).

Varieties and characteristics

When talking about what types of dental occlusion there are in adults in dentistry, there are two basic categories. In the first case, we are talking about correct occlusion, characterized by a harmonious relationship, natural facial contours, proportional shapes and symmetry of the midline and the junction of the frontal incisors. Such an anatomical structure not only ensures the aesthetics of a smile, but also allows you to fully realize the main tasks of the jaw region, which include food processing, as well as respiratory and speech functions. In turn, incorrect development is accompanied by more or less pronounced anomalies, often causing both physical and psychological discomfort to patients.

Physiological types of occlusion

Not only defective, but also natural conditions are subject to orthodontic classification. The ratio is divided into three varieties, the membership of which is determined by the indications of visual and hardware diagnostics.

Orthognathic

It is considered a reference because it provides optimal conditions necessary for the implementation of functional tasks. It is characterized by the overlap of the lower row with the upper by about a third of the height of the incisors, close contact when closing, as well as the absence of spaces and interdental gaps.

Biprognathic

A bite, the distinctive feature of which is the presence of a slight vestibular inclination, with a vector oriented towards the vestibule of the oral cavity. In this case, the frontal units retain points of contact, and the canines of the maxillary region are covered with antagonists for several millimeters.

Straight

It is diagnosed in cases when the cutting edges of the anterior incisors, which form the visible area of the smile, contact each other when closing, while the occlusion of the chewing molars remains correct. Eliminates the presence of empty areas, trema and diastemas, as well as signs of crowding.

The meaning of correct bite

The human body is a complex biological system in which each element affects the overall condition. Correct occlusal closure not only ensures the implementation of basic functionality, but also eliminates side effects such as joint pathologies, diseases of the gastrointestinal tract, as well as heart and blood vessels. The asymmetrical position of the jaws leads to incorrect redistribution of the load, which ultimately forces the muscles to readjust, causing a change in posture, causing pain and dizziness.

When is the tooth relationship considered incorrect?

Factors indicating abnormal development include:

Lack of contact between antagonists.
Diction defects.
Problems with chewing food.
Distortion of facial features.
Deformation of the jaws.
The occurrence of pain syndrome.

The presence of even one of these signs is considered sufficient grounds for diagnosis. Practice shows that the earlier deviations are detected, the easier it is for the patient to eliminate them. Dental specialists use modern methods and technologies to determine the specifics of existing bite defects and draw up an optimal treatment plan that takes into account individual indications and recommendations.

Correct bite: how to understand

To evaluate your bite, you need to see a dentist. The doctor will do this quickly and accurately. If you want to do this yourself, you should know that a correct bite satisfies the following requirements:

When the upper jaw contacts the lower jaw, an ideal contact is formed between the opposing teeth (upper and lower).
The central front teeth (incisors) are positioned symmetrically. That is, they are equidistant from an imaginary line running down the center of the face.
The dentition should be smooth, without gaps or crevices.
It is considered normal if, when closed, the upper teeth cover the lower teeth by about a third.

Important! The criteria described above, which can be used to determine the bite, are for informational purposes only. Only a doctor determines the types of bite and makes a diagnosis.

How to recognize that your child has an incorrect bite?

An abnormal bite can be corrected in adulthood, but the sooner it is noticed, the faster and easier the correction procedure will be.

Firstly, it can be visible to the naked eye. Secondly, an orthodontist can report its presence if the child comes to him for consultations regularly.

In addition, children at risk are those who:

one of the parents has an incorrect bite;
incorrect posture;
if they suck on anatomically incorrect nipples.

The presence of diseases of the ENT organs is also a reason for closer attention to the baby’s bite. Another cause may be injuries to the head and, in particular, the face.

Malocclusion in a child can be recognized by:

displacement of teeth to the sides;
the presence of cracks, gaps between teeth;
uneven placement of teeth in a row;
displacement of teeth forward or backward;
violation of the joining of the jaws when the teeth close together.

Correct bite: types

There is no ideal physiological bite. There are only types of occlusion that are close to perfect and do not require orthodontic or surgical intervention. Let's consider the main physiological types of occlusion.

Orthognathic occlusion

Orthognathic is considered the most correct bite, and is found in 90% of people with physiological occlusion. Orthognathic bite can be determined at home. Permanent teeth should fit tightly together. In this case, the upper incisors slightly cover the lower ones.

Straight bite

In a straight bite, the upper and lower jaws are the same size. At the same time, both the incisors and chewing teeth close. Individuals with a straight bite can boast a very beautiful smile.

However, such a closure is not without its drawbacks. Direct bite is dangerous due to premature destruction of hard dental tissues. This is due to the increased load on the teeth when closing. In this case, the enamel wears off faster, cracks and chips form.

Biprognathic bite

Biprognathic types of occlusion occur in children and adolescents who have the habit of thumb sucking. Also, these types of closure can develop in a baby if it is too late to wean him off the pacifier.

With this type of bite, the incisors bend slightly forward. At the same time, they come into contact, and for this reason such a bite is considered physiological.

Progenic bite

This is a normal option provided that the teeth develop normally. A feature of a progenic bite is that the lower front teeth are slightly pushed forward.

Consequences

What complications can arise if a child’s malocclusion is not corrected? Possible consequences:

tooth abrasion, premature wear, increased risk of caries;
difficulty chewing causes gastrointestinal problems;
mucosal injuries, gum inflammation, periodontal disease;
increased load on the temporomandibular joint, pain, inflammation;
breathing problems, ENT diseases;
pinched nerves in the cervical spine;
aesthetic facial defects, asymmetry;
psychological problems;
violation of diction.

Thus, malocclusion in children is dangerous for the development of diseases. It directly affects the emotional state of the individual, self-esteem, and self-confidence. If the bite is not corrected in time, physiological, psychological and aesthetic problems may develop.

Malocclusion: causes

Malocclusions are formed for a number of reasons, including:

Hereditary factors . One of the leading causes of abnormal bite is genetics. The size and shape of the jaw are determined by genes received from the mother and father. Pathologies such as too narrow a jaw, cleft bite, misaligned dentition and other disorders are often dictated by hereditary factors.
Nutrition . Malocclusion is considered one of the problems of modern civilization. In particular, we are talking about a situation where the lower jaw is underdeveloped. This is due to the abundance of liquid nutrition in childhood, which is why the lower jaw does not work fully.
Mother's illnesses during pregnancy . Some abnormal types of bite occur due to maternal illness, especially in the first trimester of pregnancy.
Wrong selection of pacifiers . An incorrect bite can develop if the nipples are not selected correctly. It is important that the baby makes an effort to obtain milk. Otherwise, underdevelopment of the lower jaw occurs.
Bad habits in childhood . For example, thumb sucking and excessive use of pacifiers. Sleeping position also affects your bite. Often a malocclusion is formed when the head is thrown back.
Diseases of the ENT organs . It is important to treat ear, nose and throat pathologies in a timely manner. With such diseases, the child is often forced to breathe through the mouth. Therefore, diseases such as sinusitis, rhinitis, adenoids and deformation of the nasal septum require adequate and competent treatment.
Physical development disorder . In particular, we are talking about diseases affecting the growth and development of bones.

Prevention

Prevention of the development of malocclusion in children begins at an early age. By following simple recommendations, you can avoid problems and maintain your baby’s beautiful smile.

Dentists' advice:

Correct attachment to the breast or bottle. Usually a new mother will be helped with this by a pediatric nurse or a breastfeeding specialist.
Prevent the development of bad habits, gradually abandon the pacifier when the first teeth appear.
Supplement your diet with solid food in a timely manner.
Keep your mouth clean.
Perform gymnastics to develop facial muscles.

The effectiveness of preventive measures can be monitored by a local dentist, whose consultation is recommended for children at least once a year.

The health of a child’s teeth affects not only the appearance, but also the functioning of the entire body. Incorrect bite is the cause of serious illnesses. Therefore, it is important to identify pathologies in time and correct them using methods available for a given age.

How to determine a pathological bite

Pathological types of bite are determined by the doctor. If you suspect a problem in yourself or your child, you should contact the dentist. Here are some features of pathological bites that you need to pay attention to:

The teeth do not close tightly. Gaps and gaps form between the upper and lower teeth.
There is partial or complete lack of contact between opposing teeth (incisors and/or chewing molars) (there is a short gap in the horizontal plane).
The upper jaw is noticeably smaller than the lower jaw or vice versa.
Dental crowding or occlusion, where teeth overlap each other.
The presence of a diastema - a noticeable gap between the incisors.
Change in appearance. For example, the lower jaw is shortened and the lips are turned inward.
Exposure of tooth roots and other defects of hard dental tissues. For example, an indirect sign of malocclusion is poor enamel and wear of the cutting edges.

At what age can a bite be corrected?

The optimal age for treating dental defects in a child is from 5 to 10 years. The formation of the body and the replacement of milk teeth with molars in this interval is well suited for gentle correction with the help of aligners without the need to install heavier systems such as braces. Please note that for children, mild malocclusions are developmentally normal and may improve on their own over time, without orthodontic intervention.

It is better to consult an orthodontist during the period of change of baby teeth - 5-6 years. At this age, it becomes possible to determine the location of future teeth, and, as a result, their defects.

Malocclusion: types

Like physiological types of occlusion, pathological ones also come in different types. Below is a classification of malocclusions.

Distal bite

This is a type of malocclusion in which the upper jaw is highly developed compared to the lower jaw. For this reason, the upper teeth move noticeably forward.

Mesial bite

In this case, the lower jaw protrudes noticeably forward compared to the upper jaw. Sometimes there is a retraction of the upper lip. Often, with mesial occlusion, the functioning of the temporomandibular joint is impaired.

Crossbite

It is observed when the jaw shifts to the right or left. In this case, 1-2 teeth are in the wrong position.

Deep bite

In this case, the upper teeth cover the lower teeth by more than half. With a deep bite, a speech defect is observed, and the oral mucosa is also injured.

Open bite

There is a large gap between the dentition during occlusion. This is due to the fact that some teeth cannot close when closed. Open bites often occur when a child sucks a finger or a pacifier for a long time.

Types of prevention of malocclusions

Prevention of malocclusion in childhood is very important, as it determines whether the child will have problems in the future. Adults should monitor the eruption of permanent teeth in children and visit an orthodontist with the child for timely detection of anomalies and bite correction.

Prevention of malocclusions involves eliminating bad habits that cause one or another anomaly: lip biting, finger sucking in children. To do this, special plates are used that block the ability to use a bad habit. In adults, such methods help cure abnormalities in the early stages.

It is important to carry out sanitation of the oral cavity in a timely manner and periodically come for medical examinations to the dentist. Children from the age of six months should be taught to chew solid food.

A good method of prevention is specially designed therapeutic exercises. When performing exercises, the patient puts the correct load on the jaw muscles, which contributes to the harmonious development of the maxillofacial system.

Bite in the absence of teeth

If the patient has no teeth left, then there is no guarantee that prosthetics will be able to achieve an anatomically correct jaw. In this case, much depends on the initial positions (what the bite was like before losing teeth). If the upper and lower jaws are positioned relative to each other within normal limits, then the bite can be straightened with minor corrections. If the patient had problems with the jaw bones, then a deeper correction is required.

In the absence of teeth, the bite is determined using wax rollers. This creates an imitation of the dentition, which allows for standard changes. For this purpose, special plates and a curved, arc ruler are used. After all measurements and preparatory procedures have been carried out, a plaster and then a regular prosthesis is initially created in the dental laboratory.

Important: bite after wisdom tooth removal . Wisdom teeth were important for ancient people, but now there is no need for them. If wisdom teeth do not cause problems for a person, then doctors recommend not touching them. However, in cases where an adult wants to correct an incorrect bite, wisdom teeth can help with this. Thus, correction of the bite in adults is possible after the removal of wisdom teeth. The space formed after their removal allows the dentition to take an anatomically correct position.

How to correct a child's bite

No matter how severe the pathology, the earlier treatment is started, the easier it is to achieve an effective result. To correct violations, there are three ways to correct bite in children:

traditional – installation of braces;
alternative (without braces) – mouth guards, plates, physiotherapy;
cardinal – surgical intervention.

Until the final stage of permanent bite formation, only alternative methods are used, but is it possible to correct a child’s malocclusion with their help?

Removable orthodontic plates

Orthodontic plates

are structures consisting of a polymer jaw-expanding base and metal arches that serve to fix the plate and align the front row of teeth.

Removable orthodontic plate
These devices are made individually, based on casts of the jaw of a small patient. To adjust the load, the devices are equipped with screws and expanders. At an appointment with a doctor, the child’s parents will learn how to perform this procedure on their own, which will save time on visits to the orthodontist.

Plates for correcting malocclusion in children are designed to be worn constantly, but the removable structures are removed during meals or hygiene procedures.

Trainers for teeth

Trainers

To correct malocclusion in children, they are mouth guards made of dense silicone.

Trainer for correcting the bite
The trainer performs several functions:

Self-corrects minor pathologies.
Prevents further development of malocclusion and prevents complications.
Helps get rid of bad habits that have caused crooked teeth.

Mouth guards for correcting malocclusion in children fix both jaws simultaneously in the correct position. But when using them, it is impossible to lead a normal lifestyle: talking, eating. Therefore, mouthguards are worn while the child is sleeping and for several hours during the day.

The process of correcting a bite with trainers is long and requires patience from the child and parents.

It has been noticed that in children who regularly use trainers before installing braces, the effect of therapy occurs faster.

Myotherapy

Myogymnastics

in orthodontics, it is a set of exercises to relax or develop individual facial muscles.

Myotherapy in orthodontics
The method serves as both a primary and an auxiliary method of occlusion correction. For each type of pathology there is its own set of exercises. The first lessons are carried out under the supervision of an orthodontist; as soon as the child learns to do gymnastics correctly, he continues to work at home independently or with his parents.

Conditions for performing exercises to correct bite in children:

Systematicity and regularity.
Sufficient application of force without jerking or pressure. The muscles feel resistance, but are not overloaded.
Cyclicality. Exercises are performed in several approaches to achieve good results.
Gradual increase in load and intensity.

Myotherapy is especially effective in correcting occlusion in combination with physiotherapy: electrophoresis, vibration massage, ultrasound, vacuum therapy, massage.

Alternative methods can correct mild pathologies of malocclusion in early childhood or slow down the development of complications and wait until the formation of the jaw is completed to begin basic treatment.

Braces

Braces

– the main way to correct uneven teeth and malocclusion in children from 12–16 years old and adults of any age.

Braces for correcting bite
They are a system of clasps fixed on the outer or inner surface of the teeth and a steel arch stretched between them.

Under the pressure of the arch, the teeth are aligned and placed in the correct position. With the help of braces, it is possible to correct almost all malocclusion pathologies. Treatment takes from 6 to 18 months and ends with the acquisition of a beautiful, even smile.

Malocclusion: consequences

Malocclusion is a problem that should not be underestimated. Over time, malocclusion can lead to the following consequences:

Premature tooth loss . This is due to two factors. Firstly, an incorrect bite increases the load on the teeth. This threatens the appearance of cracks and chips. In addition, an abnormal bite increases the risk of developing periodontal disease. This leads to accelerated tooth decay.
Damage to the gums . With an incorrect bite, gum health deteriorates. They become sensitive to temperature, chemical and physical factors. In some cases, this leads to the formation of ulcers on the gums.
Pathologies of the temporomandibular joints . The most common symptoms are a clicking sound when chewing, which should not normally be present. Then pain occurs, and the function of the joint deteriorates even more.
Diseases of the digestive system . Well-chewed food is one of the conditions for normal functioning of the gastrointestinal tract. If the bite is broken, then relatively large pieces of food enter the stomach. Due to poor initial processing of food in the oral cavity, over time a person develops eating disorders.
Psychological problems . Pathological types of bite often worsen a person’s appearance. This is how low self-esteem is formed. A person becomes overly modest, fearful and unsure of himself. Sometimes, in order to improve the situation, in addition to dental treatment, the help of a psychologist is also required.

Determination of dental occlusion

Often problems with bite are obvious, but it also happens that everything looks normal on the outside, but there is a problem. Therefore, it is better to entrust the determination of the bite to the dentist. They use special methods to determine correct or incorrect bite and prescribe treatment.

Diagnostics include:

Clinical examination

The orthodontist collects anamnesis, conducts a general examination and examines the oral cavity and nasopharynx. They examine breathing, speech formation, swallowing, chewing, biting.

X-ray examination

A panoramic X-ray or CT scan allows you to identify skeletal abnormalities, see the exact location of the teeth, the condition of the roots, and bone tissue.

Biometric test

The doctor examines the jaws, takes and records all measurements.

Functional test

Examination in a stationary position, while talking, opening the mouth in the lateral and frontal projection.

It is impossible to put the jaw back in place on your own, but the sooner the intervention begins, the better the result. It is very difficult to restore the correct position of teeth after 25 years; it is better to do this while the bite is forming.

Treatment of malocclusion

Today, malocclusions are treated using various techniques. Most often, the curvature can be corrected with orthodontic methods, but in some cases surgical correction is necessary. Let's look at the most effective ways.

Orthodontic plates

These are removable hard plates that allow you to maintain the correct alignment of your teeth. Such structures consist of a plastic base and metal elements that hold the plate in the oral cavity.

Orthodontic plates are often used in pediatric dentistry. These products help develop the habit of breathing through the nose and also stop thumb sucking. In this case, the correct bite is formed due to the work of the muscular system. Depending on the tasks assigned, different types of plates are used. These are standard plates, plates with a visor, a flap or a bead. The plates are made from hypoallergenic materials. Those with baby teeth usually have soft plates installed. For permanent teeth, hard ones can be used.

Trainers

Another way to even out an uneven bite is to use trainers. These orthodontic structures are a two-jaw mouthguard made of silicone or polyurethane. Changing the bite with trainers occurs due to muscle work.

It is noteworthy that the result of such treatment persists even after the end of the course, because muscle memory is preserved. Trainers are successfully used for the following problems:

open and deep bite types;
mouth breathing;
speech defects;
crowded teeth;
bad childhood habits (for example, thumb sucking);
incorrect position of the lower jaw.

Treatment with trainers is carried out in 2 stages:

First stage . It lasts 6 months and involves wearing soft trainers. This is necessary in order to activate the work of the chewing and facial muscles.
Second phase . Soft trainers need to be replaced with hard ones. Such trainers directly affect the position of the dentition.

Advantages of trainers:

affordable price;
absence of unpleasant sensations;
the ability to remove the structure while eating or talking.

Aligners

These are dense transparent trays for straightening teeth. Aligners are made individually for each patient. As a rule, this is a series of designs, each of which is worn for a certain period of time, and then replaced by a new one. This is a kind of cascade correction method. The disadvantage of this treatment is the relatively high price.

Braces

One of the most effective orthodontic methods of bite correction is braces. These are special locks connected in an arc. For more successful treatment, braces are also equipped with special elastic bands (or pulls). With the help of elastic bands, it is possible to increase the pressure on the dentition that needs to be corrected.

Incorrect types of bite are treated with braces in several stages:

Preparatory . At this stage, diagnostic measures and selection of a treatment regimen are carried out. Professional teeth cleaning, plaque and tartar removal are carried out. If the patient has any dental diseases, they are treated before installing braces. Then the braces are made.
Installation . The patient gets braces. Vestibular braces are installed on the outside, and lingual braces on the inside. Fastening is carried out on an adhesive basis, so it is painless. It should be borne in mind that during the first week there may be pain, which can be relieved with painkillers.
Retention . After the braces are removed, the patient needs to wear retainers for a while. This is necessary to consolidate the result. The duration of wearing retainers is determined by the doctor.

Contraindications to orthodontic treatment

In some cases, orthodontic treatment for malocclusion cannot be carried out.

Contraindications:

mental illness;
pathologies of the central nervous system;
malignant tumors;
severe diseases of internal organs.

There are also relative contraindications, in which orthodontic treatment is possible subject to certain conditions.

Relative contraindications:

Periodontitis with mobility of teeth 2 degrees.
Poor oral hygiene. If a teenager does not take care of dental hygiene, then wearing orthodontic structures (for example, braces) is contraindicated. This is due to the fact that in this case the teeth are quickly destroyed.

Surgery

Surgery is resorted to in cases where it is a malocclusion of the 3rd degree of complexity. In such cases, orthodontic techniques are ineffective. Such operations usually last several hours. After 2-3 weeks you can return to your normal life. A month later, the patient begins jaw development techniques (to be discussed with the doctor). In some cases, after surgery, the patient is prescribed braces.

Laser bite correction

A laser for correcting occlusion is used at different stages of correction. For example, after correcting a bite, teeth tend to move. For this reason, bone tissue experiences heavy loads, causing microtrauma and inflammation to occur. Laser therapy helps eliminate inflammation and promotes rapid healing.

Attention! The laser is not used as an independent method of bite correction. It is used as an auxiliary method for treating associated complications and processes.

Stages of bite formation in children

The process of developing a child’s bite can be divided into several important stages.
Each of them is characterized by changes in the structure of the jaw and has factors that influence the formation of pathology. Stages of bite development in children:

Elementary.
From birth to six months of the child. The first teeth begin to erupt towards the end of the period. The cause of pathology at this stage is a genetic predisposition or improper latching of the nipple during breastfeeding.
The process of formation of the bite of primary teeth.
Lasts until the age of three; as a rule, by the end of the period, all 20 baby teeth are in their position. At this age, the presence of gaps between the teeth is acceptable, but twisting, too close a fit, and growth in an uncharacteristic plane are considered as deviations from the norm. In addition to the above reasons, the most common factor in the development of pathology is bad habits: thumb sucking, pacifiers, toys or eating disorders. The child's diet should include a sufficient amount of solid food.
Preparation for the development of permanent dentition.
The stage continues until the appearance of the first permanent teeth. With proper oral care, no external changes are observed during this period. Bad habits can cause malocclusion. It is necessary to ensure that the child does not chew hard objects: pencils, thick books, furniture, since baby teeth are very soft and easily deformed.
Changing the temporary bite to a permanent one.
The most critical stage. It is during this period that serious pathologies begin to manifest themselves as unpleasant changes: torsion, improper growth of teeth, discrepancy between the size of the jaw and the volume of bone units, etc. On average, this period lasts up to 12 years. Factors in the development of anomalies are physiological characteristics or untimely replacement of teeth.
Formation of a permanent bite.
The teeth complete their growth and occupy a certain position in the jaw.

You can start correcting your bite from the early stages. There are several hardware and manual methods for this. Treatment with braces begins after a permanent bite has formed.

FAQ

Is it possible to correct an overbite without braces?

Yes, you can, but under certain conditions determined by the doctor. Malocclusions can be treated using orthodontic plates, trainers or aligners.

Is it possible to correct an overbite at home?

It is impossible to correct a crooked bite at home. There are exercises to strengthen the muscular system, but they are ineffective and are used only in addition to the main therapy.

How long do you need to wear braces for an overbite?

Depends on the degree of damage and the age of the patient. The minimum wearing period is 6 months. In some cases, braces are worn for up to 3 years.

Is it possible to get veneers if you have an incorrect bite?

It is possible, but only with minor deviations from the norm. Otherwise, orthodontic treatment is initially carried out, and only after that is it permissible to install veneers.

How much does it cost to correct a bite?

It all depends on the amount of work. First of all, you need to undergo a diagnosis. Mild degrees of malocclusion respond well to treatment with removable orthodontic structures. In such cases the price will be low.

Care and hygiene rules

One of the advantages of aligners is their ease of care. To keep them clean and effective throughout the correction, follow these simple rules:

aligners must be worn up to 22 hours a day, depending on the orthodontist's indications, removing them only for eating or oral hygiene;
The aligner must be cleaned regularly by rinsing the inner surface with warm running water and brushing with a toothbrush;
You should avoid too hot water so that the polymer does not deform due to temperature changes.

Aligners do not require special solutions. If you remove them, then put them in a special clean and sealed box, protected from dust and moisture.

Oral hygiene when wearing aligners also remains the same - brush, paste, mouth rinse solutions and dental floss. The latter is also suitable for effectively removing food particles.

Let us note the contraindications under which aligners cannot be installed:

periodontal disease. Like other methods of orthodontic treatment, aligners are not prescribed for periodontal disease due to the high risk of losing teeth due to destruction of periodontal tissue;
severe deformation of the jaw. Aligners work well for minor malocclusions. However, serious defects require surgery;
in the presence of impacted teeth. Often this problem occurs with molars that do not erupt and remain in the gum or even in the jaw bone. Having an aligner can interfere with their development and lead to problems in the future;
if 4 or more teeth have been lost.

In other cases, aligners are equally effective for all ages - from children to adults.

What factors influence malocclusion? Is there any way to avoid the problem?

Typically, the bite develops in people between infancy and about 17 years of age. It may be incorrect due to the following reasons:

genetic predisposition;
bad childhood habits: pacifier sucking, bottle feeding, finger sucking;
problems with the spine that have not been corrected;
chronic ENT diseases (for example, adenoiditis);
calcium deficiency, as a result of which bone tissue is not formed correctly.

It is important! If a child breathes predominantly through his mouth during sleep, play, or in a calm state, this is one of the signals of problems, which may include an incorrect bite. The faster occlusion pathologies are corrected, the less likely it is that not only dental problems will occur, but also ENT diseases.
