Orthodontic typodont

The utility model pertains to medical anatomical models, more specifically to orthodontics and orthodontic devices. The orthodontic typodont contains a model of the upper and lower jaw with a plastic cap, teeth, braces and an orthodontic arch, while the dental holes of the artificial paradont formed in a plastic base are filled with pre-melted wax. The typodont makes it possible to study the biomechanics of tooth movement in three directions under the influence of superimposed orthodontic equipment and the training of orthodontists in the practical skills of fixing orthodontic equipment with control of the movements of teeth after it is applied.

Device for distal displacement of permanent molars

The utility model pertains to medicine, more specifically to the orthodontics and orthodontic devices and can be used to treat violations of the position (mesial displacement) of the lateral teeth. According to statistics, 65% of dentoalveolar anomalies in cases of distal occlusion are associated with mesial displacement of the patients lateral teeth, which leads to shortening of the dentition, development of congestion or pathological protrusion of the frontal teeth, which are treated by removing premolars or by distalization of molars. The model contains an orthodontic implant, an active and preformed stabilizing wire arc, one end of which is fixed to the supporting tooth, the free end of the active arc is fixed to the moved tooth, and the free end of the stabilizing arc is fixed to the orthodontic implant. The active arc is a loop made of an alloy of superelastic titanium nickelide, having a circular cross-section 0.4 mm in diameter, and the stabilizing arc is made of a steel alloy and has a rectangular cross section. The device allows to improve the interaction of its working parts with the patient's dental row, and to simplify its manufacturing and installation into the oral cavity.

Device for intraocular pressure reducing

The device for reducing IOP is made in the form of a curved wire spiral made of stainless steel, with 5-7 turns of the head and tail of the spiral tightly pressed together, and the distance between the turns of the central part of the spiral is 0.1-0.2 mm . The technical result is a decrease in the traumatic nature of the operation associated with the device injection into the Shlemm-channel, and the prevention of trauma-related complications.
