The invention relates to medicine, namely to the dentist, and can be applied in orthodontics.

Famous dentures for replacing defect of dentition in the anterior children with milk teeth (Aiyama, Aiyesha, Addmachine, Wimalasundera Orthopedic stomatology of children's age. Kiev: Health, 1972, str-191, Fig. V, 167), consisting of a plastic plate, not overlapping deep alveolar bone with vestibular side, with mandatory coverage of artificial teeth bottom.

The disadvantages of these devices are:

- a significant deterioration of the fixation of the denture alone and its stabilization during the functions of chewing, swallowing and speech in the absence of clasps;

- deterioration of the fixation of the denture due to the constancy of its shape and size in terms of changing the shape and dimensions of the upper jaw of the growing child;

- appearance and, further, a fixing "bad habits" because of the need to maintain denture tongue and suction to the sky due to insufficient effective fixation alone and stabilization during the function;

- stunting anterior upper dentoalveolar arch in the conditions of constant pressure on the alveolar bone of the upper lip, onecause when prisasyvanie is poorly fixed dental prosthesis;

- additional work of a dentist and a dental technician, material costs and repeated the child's adjustment to the new dental prosthesis with regular replacements recommended by the authors.

The known device for the formation of the physiological relations of dentoalveolar arcs, including their design various elements made in the form of boards (Pahorkatina. Functional treatments in orthodontics. - M.: Medicine, 1972, p.28-36), pushing the lips, cheeks and tongue from dentoalveolar arcs and in this way protects the teeth from the pressure of the lips, cheeks and tongue, which creates favorable conditions for the location and closing the lips, growth and development of dentition and alveolar process in the areas of their underdevelopment.

The disadvantages of the vestibular shields are:

- lowering effect of treatment in connection with the use of the vestibular shield in a limited time, namely when performing exercises for lips, cheeks and tongue;

- elimination of the possibility to perform the functions of mastication and speech when using vestibular shield.

The essence of the claimed invention is that the apparatus for forming the physiological ratios dentoalveolar arcs for early removal of temporary incisors, including partial removable sphenopalatine laminar prosthesis with artificial temporary incisors, Hara is marked by the fact, what palatal plate of the prosthesis is made in the form of three segments: the anterior and two lateral interconnected in the region of the anterior palatal arch with a screw with the possibility of Autonomous displacement, and on the teeth, namely the border of the anterior and lateral segments, and the second temporary molars installed clasps, and in the field of dentition defect in the alveolar ridge with the front segment of the palatal plate is connected to the shield with the condition for the formation of a gap between the surface of the shield and gum, with the length of the contact point of the canine and the first temporary molar, and the edge of the shield Savalan and congruent contours of the transition fold.

The invention is illustrated by drawings, which depict:

figure 1 - front view; figure 2 is a bottom view; figure 3 is a view in section along the median line; where 1 is a front segment of the palatal plate, 2 - artificial cutters, 3 - right side segment of the palatal plate, 4 - left side segment of the palatal plate, 5 - extending screw, 6 - locking clasps on the fangs, 7 - retaining clasps on the molars, 8 - shield, 9 - upper lip, 10 - lower lip, 11 - alveolar, 12 - the beginnings of permanent incisors, 13 - lower incisors.

The device operates as follows: retaining clasps (6 and 7) are flush to the anterior surfaces of the abutment teeth, providing reliable support and fixat the Yu front (1) and side (3, 4) segments of the palatal plate when the unwinding of the screw (5) and the effective lengthening and widening of the upper dentition; artificial teeth (2) rely on the vestibular surface of the lower incisors (13), shield (8) pushes the upper lip (9) from the surface of the alveolar ridge (11), elimination of the pressure of the upper lip (9) to the alveolar (11) facilitates the movement of opening the beginnings of permanent incisors (12) in the vestibular direction; the tension of the soft tissues and periosteum that occur when closing the upper (9) and the bottom (10) of the lips stimulates appositional the growth of bone tissue in the area at the base of the alveolar process (11).

The device cosmetically fully replaces the defect of the upper dentition, restore occlusion and, consequently, lost the function of biting food, provides the possibility of correct articulation of the tongue during swallowing and the formation of sounds. In turn, the normalization geodinamicheskogo balance of the muscles surrounding dentoalveolar arc, creates conditions for the formation of physiological ratios of dentoalveolar arcs. The device is custom-made, removable, easy to clean with the oral hygiene, convenient in use, is exposed to cold sterilization. The possibility of loosening of the screw by the patient reduces the number of visits.
