RU2239386C2 - Method for treating frontal maxillary tendon - Google Patents

Abstract

FIELD: medicine, orthodontics.

SUBSTANCE: one should apply orthodontic apparatus that contains certain expanders, a screw and a stopper. Palatine suture should be opened with the help of a screw in frontal maxillary section till development of artificial diastema being 4 mm, not less. Diastema should be closed due to certain technique. Results of therapy should be fixed with retention apparatus. The method enables to shorten therapy terms, improve functional and esthetic results and prevent complications.

EFFECT: higher efficiency of therapy.

Description

The present invention relates to medicine, namely orthodontics, and can be used for the treatment of dentofacial anomalies with narrowing of the upper jaw.

Known methods of treatment using various orthodontic appliances to expand the upper jaw. With the expansion of the jaw there is a change in the shape and size of the dentition [1, 2, 3, 6].

There is a method of treatment for narrowing of the upper jaw using an orthodontic plate with incisor expanders, taken as a prototype [5]. The disadvantage of this method is that the expansion of the upper jaw occurs slowly due to the need to expand the entire jaw, including the region of the maxillary tubercles and buttresses in the molars. When the apparatus is removed by an undisciplined patient, relapse of narrowing and other abnormalities is possible.

The technical result is a reduction in treatment time, improved functional results, the prevention of complications.

The specified technical result is achieved by placing an orthodontic device, which additionally contains a stopper in the distal section, opening the palatine suture with a speed of 1/4 revolution until the formation of an artificial diastema of at least 4 mm, and the closure is carried out using the edgewise technique.

Figure 1 shows a device for expanding the frontal section of the upper jaw according to the proposed method, figure 2 - the oral cavity of the patient B. before treatment, figure 3 - the state of the upper jaw after expanding the frontal section with the formation of artificial diastema, figure 4 - the oral cavity at the final stage of treatment.

The proposed method for the treatment of narrowing of the upper jaw in the frontal area is as follows.

Stage 1 - impose an apparatus containing cutter expanders 1, an expanding screw 2 and a stopper 3 in the distal section (figure 1). A week after the application of the apparatus, the activation of the screw is prescribed for 1/4 revolution every other day. The average expansion time ranged from 2 weeks to 2 months, depending on the degree of narrowing of the dental arch and the lack of space for individual teeth [4]. The first stage of the expansion of the upper dental arch ends with the formation of an artificial diastema from 4 to 10 mm due to the stopper installed in the distal section of the removable device.

Stage 2 - cutter expanders are cut off and the apparatus is left in the oral cavity without screw activation for 2-3 months. The closure of the diastema is carried out within 1 month using conventional edgewise technique [6]. This creates a place for closely spaced teeth of the upper jaw. The timing of further treatment depends on the severity and complexity of the dentofacial anomaly.

Stage 3 - fix the result of treatment by the generally accepted method-retention apparatus [2, 6].

As an example, we cite an extract from the medical history of patient B., 12 years old, who turned to the Department of Orthopedic Dentistry of the Belarusian State Medical University with complaints about the incorrect position of the front teeth on the upper jaw and the protrusion of the chin.

During a clinical examination of the oral cavity revealed: mesial occlusion of the dentition in the lateral departments (class III according to Engle). The narrowing of the dentition of the upper jaw in the lateral regions in the premolar region is the front of 6 mm, a slight narrowing in the region of the molars is 2 mm, and the frontal section of the upper jaw is underdeveloped. Reverse incisal overlap with sagittal fissure 1.5 mm. The close position of the front teeth on the upper jaw with the lack of space in the dentition for fangs that have not yet erupted (figure 2). Short bridle and low position of the tongue, infantile type of swallowing.

The treatment plan, including the expansion of the upper jaw with a 8 mm extender, Stage II - creating a place by extending the dental arch of the upper jaw for proper eruption of fangs and normalization of occlusion using the edgewise technique. Using the incisor expander achieved a significant expansion of the frontal section of the upper jaw (figure 3). Created a place for teething and normalized occlusion using fixed technology (figure 4). Good occlusal and aesthetic results were achieved. In this case, the patient noted an improvement in nasal breathing, obviously associated with the expansion of the upper respiratory tract in the nasal passages.

According to the described method, 12 patients were treated. The proposed method of treatment compared with known methods of treatment of frontal narrowing of the upper jaw has the following advantages:

- reduction of treatment time by 2 times;

- allows you to create a place for crowded teeth and normalize their position;

- rapid opening of the palatine suture with the formation of an artificial diastema and its closure within 2 - 2.5 months does not give complications, which is confirmed by x-ray observations in the area of the palatine suture;

- complex treatment using the Edgewise technique at the final stage enables the body to move teeth and get good aesthetic results.
