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

Known methods of treatment using a variety of 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 with orthodontic braces with rescueme extender, taken as a prototype [5]. The disadvantage of this method is the area of the maxillary cusps and buttresses in the molar region. When removing apparatus unruly patient relapse narrowing and other anomalies.

The technical result - the reduction of treatment time, improve functional results, prevention of complications.

This technical result is achieved by the fact that impose orthodontic device, which additionally contains in the distal stopper, conduct disclosure palatal suture speed 1/4 turn before the formation of artificial diastema not less than 4 mm, and closing out aguis technique.

In Fig.1 shows a device for extending the front portion of the upper jaw by the proposed method, Fig.2 - oral cavity of the patient Century before treatment, Fig.3 - state upper jaw after the expansion of the frontal area with the formation of artificial diastema, in Fig.4 - the mouth at the final stage of treatment.

The proposed method for the treatment of narrowing of the upper jaw in the anterior part consists of the following.

step 1 - lay apparatus containing cutting extenders 1, which extends the screw 2 and the stopper 3 in the distal (Fig.1). A week after blending apparatus appoint activation screw 1/4 turn every other day. The average time of expansion was from ervy phase of expansion of the upper arch ends with the formation of artificial diastema from 4 to 10 mm thanks to the distal removable device with the stopper.

step 2 - cut cutting extenders and leave the device in the oral cavity without activation screw for 2-3 months. Closing diastemas performed within 1 month using common aguis techniques [6]. This creates a place for technoecology teeth in the upper jaw. Terms of further treatment depends on the severity and complexity of dentofacial anomalies.

stage 3 - fix result of treatment common way is the retention apparatus [2, 6].

As an example, here is an extract from the medical history of a patient Century, 12 years old, which appealed to the Department of prosthetic dentistry bgmu with complaints about incorrect position of the front teeth on the upper jaw and the protrusion of the chin.

At clinical examination of the oral cavity revealed: anterior occlusion of the dentition in the lateral parts (III class Anglo). The narrowing of the dentition of the upper jaw in lateral sections in the area of premolars - front 6 mm, small narrowing in the molar region is 2 mm, the underdevelopment of the frontal portion of the upper jaw. Reverse cutting overlap with sagittal slit of 1.5 mm Close position of the front teeth on the upper jaw with the lack of space in the dental arch for canines that have not yet erupted (Fig.2). Short temper is Reztsova expander 8 mm, Stage II - the creation of space by lengthening the dental arch of the upper jaw for proper eruption of the canines and the normalization of the occlusion with aguys technique. Using the tool extender achieved a significant expansion of the frontal portion of the upper jaw (Fig.3). Created space for the eruption of the canines and normalized occlusion using fixed machinery (Fig.4). Achieved good occlusal and esthetic results. However, the patient reported an improvement of nasal breathing, obviously associated with the extension of the upper respiratory tract in the area of the nasal passages.

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

- reduction of treatment time 2 times;

- allows you to create space for crowded teeth and to normalize their situation;

- fast erection palatal suture with the formation of artificial diastemas and its closing time 2 - 2.5 months, no complications, which is confirmed by x-ray observations in the field palatal suture;

- comprehensive treatment using aguis techniques at the final stage darmali
