More than 10 years ago, it was customary to correct the bite starting from adolescence. Dentists have proven that this is wrong.
Today, orthodontists have developed a technique that can prevent the development of anomalies, starting from early childhood. This saves not only money, but also time. After all, it is better to take preventive measures in childhood than to wear braces in adulthood.
The Haas apparatus can cope with this task. Dentists consider this device unique, and for good reason.
Design of the Marco Rosa apparatus and the Haas apparatus
The Marco Rosa apparatus (its creator is Dr. Marco Rosa) is very similar to the Haas apparatus and is a non-removable intraoral plate apparatus, made individually from dental casts. The device is secured with rings to the chewing teeth and has additional support on the fangs. In the central part of the plate there is a screw for expanding the upper jaw.
The Marco Rosa apparatus and the Haas apparatus are used to expand the maxilla. The advantage of these devices for maxillary expansion is that you cannot forget to put them on or lose them. The devices operate around the clock, which improves the quality of treatment and reduces the time of orthodontic treatment.
When developing the design of the device, the child can choose the color of the plastic parts, add decorations to them - pictures, sparkles, etc. This increases motivation and helps eliminate anxiety about the upcoming treatment.
The principle of operation of the technique
This device expands the parameters of the maxillary row by opening the palatal suture. The whole process occurs in the following sequence:
- The device is secured in the mouth so that the base lies in the center of the roof of the mouth, and the fasteners and rings are attached to the canines and molars, respectively.
- The dentist draws up a schedule that indicates a gradual increase in the force of the expansion mechanism on the jaw.
- The increase in pressure on units of the dentition occurs gradually. The result of this effect is the divergence of the jaw halves and the appearance of additional space in the suture area, which is gradually filled with bone tissue.
After enlargement of the maxillary line, gaps may form between the anterior elements. To eliminate them, the doctor prepares a program to further change the position of these teeth, which may include correction with a brace system or other orthodontic structure.
The mandibular row in children immediately responds to changes in the upper jaw and adapts to its new position. This will take approximately 1-2 months.

When to use the Marco Rosa apparatus and the Haas apparatus
The Marco Rosa apparatus, like the Haas apparatus, is used to expand the upper jaw in children aged 6-9 years during the period of occlusion change.
The use of the Marco Ross apparatus or the Haas apparatus allows us to solve the following problems:
- lack of space for permanent teeth – growth of teeth in the second row, crooked teeth;
- crossbite;
- advancement of the lower jaw;
- speech therapy problems;
- violation of nasal breathing associated with the narrowness of the nasal passages.
Causes of narrowing of the upper jaw
- genetic reasons;
- mouth breathing due to insufficient patency of the nasal airways (adenoids, polyps, allergic edema);
- a constantly open mouth (not associated with mouth breathing) due to improper functioning of the facial muscles.
Structure of the structure
The device is non-removable and is capable of stretching the upper jaw and moving the teeth as needed to achieve aesthetics and functionality. The device consists of:
- a frame made of medical steel, which eliminates the occurrence of an allergic reaction;
- a plastic plate with the help of which the surface of the sky expands.
- screw - an expander, with the help of which, if necessary, the parameters of the device are changed;
- clasps and rings are fasteners.
- Haas is used to correct temporary occlusion in order to prevent the development of pathology in the placement of permanent teeth. Attached to molars and upper canines.
There are no ready-made devices for sale. Each new specimen is made to order, taking into account the clinical picture and defects present in the little patient.
The device is fixed using dental cement or composite.
How the Marco Rosa appliance and the Haas appliance work for maxillary expansion
After consultation and diagnosis, the orthodontist makes calculations and transfers dental impressions to the dental laboratory. The production time for the device is about 10 days. The orthodontist fixes the fixed appliance with special glue onto previously cleaned teeth. Activation of the screw (turning the screw with a key) causes expansion of the palatal suture and a gradual increase in the size of the upper jaw.
Getting used to the Marco Rosa apparatus (Haas apparatus) takes several days (diction is slightly impaired). The plate does not put pressure on the palate, but only lightly touches it. From the outside, the Rosa apparatus is practically invisible.
Activation of the screw to expand the upper jaw is carried out by parents at home, at the same time every day, according to a scheme developed by the orthodontist. The expansion of the upper jaw lasts about 3-4 weeks. Then the device remains on the child’s teeth for another 7-8 months to stabilize the achieved result.
During treatment with a fixed apparatus for expanding the upper jaw, no special hygiene is required; it is enough to brush your teeth twice a day and use an irrigator.
When the upper jaw expands, the nasal passages expand, which is important for patients with impaired nasal breathing.
The Marco Rosa apparatus expands the upper jaw, but since the growth of the jaws is interconnected, the lower jaw is also affected, it adapts to the changes that occur.
Examples of treatment with the Marco Rosa apparatus from the practice of orthodontists “Dial-Dent”
Example 1
Girl 7 years old. Open bite, narrowing of the upper jaw, constantly breathes through the mouth.
With the help of the Marco Rosa apparatus, the expansion of the upper jaw to the required size was achieved, and nasal breathing was normalized. Orthodontist M.P. Sleptsova, assistant orthodontist L. Rodina.
Example 2
Boy 8 years old. Narrowing of the upper jaw, advancement of the lower jaw. The beginning of the development of class 3 malocclusion (in adults with class 3 malocclusion, more complex and lengthy treatment is required).
As a result of the treatment, the upper jaw was expanded, and correct closure of the teeth in the anterior region was achieved. Orthodontist M.P. Sleptsova, assistant orthodontist L. Rodina.
Example 3
Boy 8 years old. Deep incisal overjet, not enough space for permanent teeth (second incisors).
After treatment with the Marco Rosa apparatus, the size of the jaws was normalized, and enough space was created for the eruption of permanent second incisors. Orthodontist M.P. Sleptsova, assistant orthodontist L. Rodina.
Will I need braces later?
Orthodontic treatment in children using a fixed Marco Ross appliance helps to normalize the size of the upper jaw, which prevents negative changes in the facial skeleton (protrusion of the lower jaw or its retraction, severe narrowing of the upper jaw), which change the harmony of the face. If the problem of underdevelopment or narrowing of the upper jaw is left unresolved in childhood, surgical expansion of the upper jaw may be required in adulthood.
You may need treatment with braces or mouth guards in the future, but this treatment will be faster and more effective. Quite often, additional wearing of braces after orthodontic treatment with a fixed Marco Rosa appliance is not required.
Cost of treatment
The average price for fixing the device in large dental centers reaches 16-19 thousand rubles, which is considered an expensive manipulation.
If there is a need for additional dental procedures or re-fastening of some elements of the device, the cost increases by several thousand rubles.
Some patients, even after removing this device, still need to continue correction using a brace system. Its installation is already paid for separately, and the final price of treatment depends on several factors: the type of braces and their material, the design features of the selected model.
Features of the use of the Marco Rosa apparatus in Dial-Dent
Family Dental Orthodontists have a comprehensive approach to correcting malocclusion in children, so the clinic employs an ENT doctor and a speech therapist who help eliminate the causes of malocclusion, thereby increasing the effectiveness and stability of orthodontic treatment.
If there are problems with nasal breathing, ENT doctor A.V. is involved in treatment. Arkhandeev. The participation of an ENT specialist in orthodontic treatment is very important, since without normalization of nasal breathing, the treatment result will not be stable and no device will help!
If there is improper muscle function, incorrect position of the tongue, infantile swallowing, if the mouth is constantly open, even when breathing through the nose, a speech therapist - myofunctional therapist T.B. takes part in the treatment of children. Zukor. Classes with a speech therapist normalize the tone of the facial muscles, eliminate excessive pressure of the tongue on the teeth, normalize swallowing and breathing - that is, they remove factors that provoke malocclusion.
See the price list of the clinic for the cost of the Marco Rosa device.
Possible difficulties
The first days after fixation of the Haas apparatus, the child may experience some discomfort. As a rule, this is a feeling of nausea and vomiting, difficulty chewing and swallowing food, and increased salivation.
In the future, wearing the structure may be accompanied by the following difficulties:
- violation of the pronunciation of certain sounds;
- damage to the tongue and cheeks due to contact with the elements of the device;
- difficulties in eating.
In addition, parents of children undergoing treatment with the Haas apparatus note that difficulties may arise with proper care of the oral cavity and the device itself, as well as problems with regular activation of the screw mechanism. In isolated cases, decementing of the structure and damage to the composite on the teeth is observed.
