Which dentures are best to install: answers and nuances

Not everyone manages to keep their teeth intact throughout their lives. When teeth are lost, the patient loses the ability to smile beautifully, and he experiences disturbances in speech and chewing functions. Orthopedic dentistry is designed to solve these problems. Restoration of the structure and functions of the masticatory apparatus occurs through the installation of orthopedic structures. Modern designs for prosthetics completely replace lost teeth. They are adaptive, hypoallergenic, and have a long service life.

Indications for installation of a prosthesis

The general indication for prosthetics is damage or absence of a certain number of dental units. Dental defects lead to ineffective chewing of food. The bite is disturbed, the aesthetics of the smile suffers. The most common indications for prosthetics are the following disorders:

Adentia (complete or partial loss of teeth). Restoration of the dentition is carried out by removable prosthetics or implantation of dental units.
Complete or partial destruction of the coronal part of the tooth, in which filling is impractical. When preserving the root, a pin structure or stump tab is used.
Pathological abrasion of enamel, which is a systematic violation of the enamel layer of dental units. The loss of hard dental tissues leads to malocclusion.
Traumatic damage to teeth. The patient may be offered various options for restoring the dentition, depending on the severity of the situation.
Pathology of the alveolar process leading to serious malocclusion. A frequent consequence of partial edentia, leading to the restructuring of the alveoli and a decrease in the functionality of the dentition.
Single and multiple dental defects. The patient can be offered various design options depending on the existing problems.

Implant shape

Observations show that the best shape is for implants made in the form of a threaded cone. This design allows you to change the angle of the implant during installation, which helps position the crown in a natural way.

The shape of the upper (coronal) part of the implant, otherwise called the neck, also plays an important role. The best option is an implant neck with grooves, shaped like an inverted cone. The bone tissue around such an implant will quickly grow, giving the tooth a natural appearance.

Types of prostheses

Modern orthodontics offers many types of dental restoration. Each method has its own advantages and disadvantages and is used to solve a particular problem. The type of prosthesis and method of prosthetics are selected by the attending physician together with the patient, based on the clinical situation, budgetary capabilities and patient preferences. Orthopedic structures are distinguished by the method of fixation, the material of manufacture, the defect being replaced, and the type of fastenings in the oral cavity.

Classification by method of fixation

Based on the method of fixation, a distinction is made between removable and non-removable structures. A very special type is fixed dentures on implants.

Removable structures. They can be removed from the mouth independently. They solve the problem of the absence of one or more units in the dentition. Inexpensive and easy to care for.
Fixed structures are permanently fixed in the oral cavity. They are durable, strong and efficient. They have a higher cost.
Implantation is the most complex and expensive type of prosthetics. Implants are a multi-component structure that is inserted into the bone tissue of the jaw and replaces the root part of the teeth. On their basis, the restoration of the dentition is carried out.

Classification by material of manufacture

In modern dentistry, many materials have been developed for the manufacture of prosthetic structures. Here are the four main types:

Plastic structures are made from polymerized acrylic. This lightweight and durable material is inexpensive and available. The lightweight porous structure ensures a tight fit, which significantly reduces the adaptation time. Under heavy loads, plastic prostheses are prone to loosening and are therefore short-lived. Used for temporary use.
Nylon prostheses are made from soft, hypoallergenic synthetic material. They are secured in the mouth using special clasps. The disadvantage is its short service life. The chewing load is distributed unevenly, which can lead to bite problems.
Zirconium dioxide structures. Zirconium dioxide is a durable natural mineral, naturally enriched without the presence of synthetic impurities. Used for the preparation of fixed dentures. It has many advantages: it holds the chewing load well, its shade is close to natural enamel, and it has low thermal conductivity. Zirconium dentures are not used to treat severe malocclusions, since a strong crown begins to destroy neighboring teeth.
Ceramic dentures are made from specially treated ceramics with the addition of lithium disilicate. The crown material is very durable and reliable, its structure is closest to tooth enamel. Ceramic dentures have the highest aesthetics, therefore they are used for prosthetics in the smile area.

Classification of dentures according to the volume of the replacement defect

Depending on the clinical situation, the patient may be indicated for a complete or partial denture:

Complete dentures are removable or conditionally removable structures used in the absence of all units in the dentition. A complete denture simulates the entire dentition. The base of the prosthesis rests on the gums and helps fix the structure in the oral cavity.
Partial dentures help restore dentition when several teeth are missing. They imitate a fragment of the dentition, replacing several nearby missing dental units or teeth lost in different parts of the jaw.

Classification of prostheses by type of fastenings

Depending on the method of fastening the prosthesis in the oral cavity, the functional load on the supporting tissues is distributed differently. The following types of orthopedic structures are distinguished:

Lamellar dentures are a type of removable structures. Effective for partial or complete edentia. They differ in the material of manufacture and the method of attachment in the oral cavity. Attached directly to the mucous membrane.
Bridges are non-removable structures used in cases where several dental units are missing in a row. They are attached to dental units spaced apart from each other and ground for crowns.
Supported or clasp dentures are distinguished by a special way of transferring the load: through the supporting teeth, periodontium and mucous membrane. This method is called semi-physiological.

Beam prosthesis on implants: turnkey price in Moscow

Prices for beam dentures in Moscow dental clinics may vary, since the final amount depends on many factors. Firstly, the cost of treatment is largely determined by the number of implants implanted, since it is the titanium root and the service for its installation that require the greatest financial investment from the patient. On average, the price of a beam prosthesis on implants (one jaw) will cost the patient 300-350 thousand rubles. This amount includes the implantation of 4 to 16 implants, taking impressions, making a beam and orthopedic structure, all consultations and examinations, as well as a guarantee. Many clinics have promotions that allow you to install a turnkey beam prosthesis. The patient is offered a specific treatment protocol, which involves the implantation of implants of a specific brand and fixation of the prosthesis. For many, this is a good opportunity to save money, because the turnkey price of a beam prosthesis on implants is less than the cost of a similar procedure without a promotion.

How to choose the right dentures

The selection of a denture is made by the attending dentist together with the patient. After the initial examination, the doctor assesses the clinical situation and advises the patient, explaining what type of prosthetics is indicated for him. The patient makes a decision taking into account the doctor’s recommendations and his preferences.

Doctors at the Consilium Dent dental clinic will provide a free initial consultation on the selection and installation of orthopedic structures. After the initial examination, the dentist will select the optimal prosthetic option and advise the patient on how to prepare for prosthetics. He will talk in detail about how to care for the oral cavity during and after prosthetics. When choosing, the number of missing teeth, the condition of the tooth bed and gums, financial capabilities and the desire of the patient are taken into account.

Contraindications

Not all patients can get fixed dentures, because there are strong contraindications:

pathologies of the temporomandibular joint;
tooth mobility;
chronic periodontal disease;
pregnancy;
severe bruxism;
oncological diseases, blood diseases, mental disorders.

There are few absolute restrictions on installation. You can always choose the option of fixed prosthetics for each patient, taking into account his individual characteristics.

Removable dentures. What to prefer?

If all or a significant part of the teeth are lost, the patient will be offered the installation of a removable denture. The removable design is a plastic plate that fits tightly to the mucous membrane and follows its shape. This ensures its strong attachment in the oral cavity. Artificial teeth are attached to the plate, imitating the patient’s own lost dental units. There are two types of removable structures: partially removable and completely removable.

The best partially removable designs

Partially removable dentures are used for partial restoration of the dentition. This type of denture is indicated if only part of the teeth are missing. Plastic and nylon are used for manufacturing. Special hooks or special clasps are used as fastening means. The fasteners are quite strong and provide reliable fixation of the dentition.

Main advantages and disadvantages

Partially removable structures are universal and have many advantages:

The chewing load is evenly distributed, which ensures the safety of the dentition.
The oral care procedure is simple and easy.
Durable clasps provide reliable fixation in the oral cavity.
The prosthesis ensures complete restoration of chewing function.
Due to the uniform load, deformation of some dental units is excluded.

Among the disadvantages are the following:

Dentures are quite expensive.
Not all designs are sufficiently aesthetic, so they are not suitable for restoration of a row in the smile zone.
Dentures require periodic adjustments.

Removable structures for complete dentures

This type of structure is used for complete restoration of the dentition in cases of total edentia. These are light and durable dentures that are in good contact with the oral mucosa. Typical denture materials used for complete dentures are nylon or acrylic. The fastenings are made in the form of so-called suction cups.

Advantages and disadvantages

Among the advantages, the following should be noted:

The designs are easy to manufacture, which determines the low price.
In case of breakdowns or damage, they can be easily restored.
Cover a significant part of the sky, which makes contact very reliable
Easy to care and use.

There are also a number of disadvantages:

The structures wear out quite quickly, since the work of the masticatory muscles is not always coordinated.
Due to constant pressure, the volume of tissue in the jaw joint gradually decreases. This impairs the retention of the prosthesis, and it may fall out when speaking.
If the prosthesis is not positioned correctly, pain may occur in the mouth.

Let us compare the removable structure made of acrylic and nylon.

Acrylic processes are more affordable.
Acrylic dentures can break over time, while nylon dentures are made of flexible and durable material, so the likelihood of breakage is minimal.
An acrylic prosthesis does not deform; a nylon prosthesis can change shape.
Nylon has a smooth structure, does not absorb odors, does not stain, and is non-toxic. Acrylic is a more porous material and is susceptible to staining and staining over time.
The color of nylon is closer to the shade of natural enamel and looks aesthetically pleasing. Acrylic has a wide range of shades; it is possible to choose an option that is as close as possible to the individual shade of the teeth.
Nylon constructions are more hypoallergenic than acrylic ones

Removable dentures without palate

Sandwich dentures are designed for partial prosthetics and are an arch made of dense polymer that imitates the jaw arch. They are fixed to the molars that are preserved on both sides of the jaw. The fasteners are telescopic crowns that fit tightly and fix the product.

The advantage of these designs is that they leave the palate and sublingual space free, which ensures the preservation of diction and the natural sensitivity of taste buds. In some patients, such prostheses cause a gag reflex, which can make wearing difficult. Such patients are recommended to opt for the clasp system.

Expert advice

There is no clear answer to the question of which prosthesis to choose in a given case. The structural features of the patient’s jaw apparatus, his age, and the severity of the problem are of great importance. Approximate recommendations are given in the table:

Situation	Type of prosthetics
Clinical picture	Recommended type of prosthetics
Availability of dental units suitable for fastening the structure	Conditionally removable prosthesis
The dentition lacks a large number of dental units, and the installation of bridge-like structures or implantation is impossible	Removable prosthetics
Molars or incisors are completely absent from the dentition	Removable prosthetics. It is recommended to choose acrylic dentures
Molars and premolars are missing	Partially removable prosthetics
Requires installation of temporary prostheses	Partially removable prosthetics

Fixed dentures. Which ones to choose?

Fixed prosthetic structures are firmly fixed in the patient’s oral cavity with cementing material and are not intended for self-removal. There are three main types of fixed structures: crowns, bridges, microprostheses.

Crowns

A dental crown is a non-removable orthopedic structure of a natural shape that covers the coronal part of a tooth or a separate area of its surface. Crowns are made from high-quality materials: metal, zirconium, porcelain, ceramics, plastic.

Advantages and disadvantages of crowns

The main advantage of dental crowns is that they are able to completely restore the functionality of the dentition. Other benefits include:

strength;
aesthetics;
low price;
long service life

Among the disadvantages of structures of this type are:

metal crowns are not aesthetically pleasing enough, so they are not used in the smile area;
it is not always possible to choose a design color that fully matches the color of natural enamel;
in some cases it is necessary to sharpen the tooth.

Bridge structures

A bridge is a type of fixed prosthesis used to replace significant defects in the dentition. A bridge rests on two dental units spaced apart from each other and replaces several destroyed, consecutive dental units.

Advantages and disadvantages of bridges

Bridges are structures that are designed for use in cases of significant defects in the dentition. This quality determines the main advantages of the structures:

When chewing, the load is evenly distributed, determining the long service life of the prosthesis.
The use of a bridge helps prevent atrophic processes in bone tissue. They begin due to insufficient load on the jaw in the absence of a significant number of dental units.
A bridge can ensure normal grinding of food during chewing, and therefore maintain the health of the patient’s digestive system.

The disadvantages of bridges include the following:

A structure that replaces several dental units is quite expensive.
Teeth that serve as support have to be ground down and depulped even if they are healthy.

Microprostheses

Microprostheses are microstructures made of ceramic or composite material that serve to restore the damaged part of the tooth surface. These include dental inlays, veneers and lumineers.

Microprosthetics is a gentle technology designed to preserve severely damaged teeth. It allows you to protect the front wall of the tooth and restore the aesthetics of the dentition.

Advantages and disadvantages of microprostheses

The advantages of microprosthetics are obvious:

A microprosthesis effectively hides defects and strengthens the tooth, which prevents its further destruction.
An ideally selected shade makes the tooth indistinguishable from other units of the dentition.
Microprosthetics does not require grinding of teeth.

The disadvantages are:

Microprosthetics cannot be used for carious teeth.
The cost of the procedure is quite high.

When choosing the appropriate type of prosthetics, the dentist aims to solve the patient’s problem in the most acceptable way.

Situation	Type of prosthetics
One or more incisors are destroyed	Dental crown made of ceramics
Completely missing dental unit	Bridge prosthesis
Chipped edges of the tooth	Microprosthetics (veneers)
Chewing teeth destroyed	Dental crown. Recommended materials: metal, metal ceramics

Which prosthesis to choose: removable or fixed?

Knowledge of the advantages and disadvantages of removable and fixed structures will help you choose the optimal type of prosthetics

Kinds	Advantages	Advantages
Fixed structures	High level of reliability	There is a need to grind down adjacent teeth
	Quick adaptation to the prosthesis and comfortable wearing	Sometimes the mucous membrane rubs when worn, making correction difficult
	High aesthetics	While the process of adaptation is underway, changes in diction and taste of food may be observed.
	The chewing load is distributed evenly	High cost with good quality material
	Easy to care for	When installing metal crowns, a metallic taste in the mouth is possible.
	With proper care, a long service life will be ensured.
Removable structures	Maintenance is simple and easy	Over time, the denture may become dislodged when eating.
	Low cost	There is a risk of developing stomatitis
	The installation procedure is short	In some cases it is necessary to use a fixing paste
	Periodontal disease is not an obstacle to installing a prosthesis	When worn, a gag reflex may occur
	This type of prosthesis can be manufactured quickly	When worn, the shape of the face may change

The choice of the type of prosthesis for each patient occurs individually. Dentists recommend paying attention to removable structures for the following problems:

with complete or partial edentia;
if there are pathological changes in the periodontium;
if oral care is not thorough enough;
if there are terminal defects of the dentition.
in case of financial difficulties.

Fixed dentures are recommended for choice in the following cases:

when no more than one or two units are missing in the dentition;
if there are significant chips in the enamel;
with pathological abrasion of enamel;
with yellowed enamel;
if it is necessary to restore the smile area;
in the presence of carious teeth.

Implant rejection

If in the first days after implantation you began to experience severe, unstoppable bleeding, the gums around the implant became very swollen and inflamed, and there was acute pain that did not go away even with painkillers, then you may have experienced implant rejection. You need to see a doctor urgently. At the same time, the norm is swelling, bleeding of the gums and aching pain during the first two to three days after implantation. If these symptoms last longer, then this may also be a sign of implant rejection.

In addition, sometimes implant rejection occurs without any symptoms. If, in the subsequent period after installation of the implant, inflammation, swelling, or pain appear around it, these may be signs of infection. If measures are not taken in time, the jaw bone will become inflamed, which will also lead to the loss of the implant.

Nowadays, the survival rate of implants is 95-97%. However, the dentist should warn patients about the possibility of implant failure. He still has to study the patient's medical record to find out if he has any contraindications to installing the implant. Such contraindications most often become the cause of rejection.

Refusal of postoperative and preventive medical supervision, heavy load on the implant in the first days after installation, smoking and poor oral hygiene also cause implant rejection.

Disadvantages of the implantation method

We found that the implantation method has virtually no disadvantages, except for contraindications in some patients. The only drawback is the high cost of implants.

Survival and service life of implants

The healing time of implants is: on the upper jaw - from 6 months, on the lower jaw - from 3 months. Much here depends on the age of the patient, the quality of his bone tissue and the experience of the doctor installing the implants. But, if the implant is successfully implanted, it is almost impossible to remove it from the jaw.

A well-established implant will serve you for at least thirty years. If you follow your doctor's recommendations, the implant will last a lifetime. This refers to the part of the implant that is placed into the gum, the plate and abutment. The crown placed on the implant will have to be replaced, but it will last 10-15, or even 20 years.
