Description

The invention relates to medical equipment, namely to devices used for early removal of milk teeth to eliminate the mesial bite, and can be used in orthopedic dentistry, mainly for children.

Various orthodontic devices are known for the treatment of mesial occlusion. For example, the Frenkel type III function regulator (FP-III) is known, including the vestibular arch, upper lip pellets, cheek shields, palatal arch, palatal protrusion arch, lingual arch, occlusal lining for 6 teeth (see Horoshilkina F. Ya ., Persin LS "Orthodontics. Treatment of dentofacial anomalies with modern orthodontic appliances. Clinical and technical stages of their manufacture. Book II. Moscow, 1999, pages 78-84).

A disadvantage of the known type III Frenkel function regulator is the absence of artificial teeth on the upper and lower jaw, which makes it impossible to chew food in the absence of 10 or more milk teeth, and the fact that the known device does not eliminate diastema in the region of the upper central incisors and does not create a place for teething of the second lateral upper incisors in children.

A multifunctional double-jaw orthodontic prosthesis device for treating a distal deep bite is known, containing a base, fixing and strength elements fixed to a base, which is made of two removable plates - the upper and lower, on which artificial chewing teeth are installed instead of the missing ones, while the upper base plate equipped with round clasps for 6 teeth and M-shaped hooks soldered to the base for elastic rods in the area of chewing teeth and Kalvelis hand-spring for eliminating diastema, and the lower base plate contains two clasps for 6 teeth, two removable labial pelota installed in bushings with locks welded into the base, and hooks for elastic rods (RF patent for PM No. 46919, publ. 10.08.2005, ., Bulletin No. 22).

A disadvantage of the known prosthetic apparatus is the lack of a vestibular arch with M-hooks on the lower base plate and the absence of occlusal lining, which does not allow the use of the known prosthetic apparatus for the treatment of a mesial occlusion.

The objective of the invention is to remedy these shortcomings.

The problem is solved by a multifunctional double-jaw orthodontic prosthesis device for the treatment of the mesial bite, containing a basis, fixing and strength elements fixed to the basis, in which the basis consists of two removable plates - the upper and lower ones, on which artificial chewing teeth are replaced instead of missing ones, while the upper base plate is equipped with occlusal overlays in the 6/6 area, round clasps for 6 teeth with hooks for elastic rods, soldered to the base with two labial pelots in the region masticatory teeth, and protectors made with the possibility of their conversion after the incisors are advanced forward into Kalvelis hand springs to eliminate diastema, and the lower base plate contains two clasps for 6 teeth and a vestibular arch with M-shaped hooks for elastic rods in the area of temporary fangs. Elastic traction made in the form of rubber rings. The base plates are made with the possibility of drilling holes in them for the growth of new teeth, for example, the second lateral upper incisors.

The invention is illustrated by drawings, where in Fig.1 shows a General view of the proposed apparatus prosthesis, Fig.2 is the lower part of the prosthesis, Fig.3 is the upper part.

A multifunctional double-jaw orthodontic prosthesis device for the treatment of the mesial deep bite contains a basis consisting of two removable plates - the upper 1 and lower 2 (Figs. 1, 2, 3). On the upper plate 1, artificial chewing teeth 3 were installed instead of those absent from the patient, on the lower plate 2 artificial chewing teeth 4 were installed instead of those missing. The upper base plate 1 is equipped with occlusal pads 11, two labial pelots 10, round clasps 5 mounted on the 6th teeth with hooks 6 for elastic rods 7 in the area of chewing teeth, and protectors 8, which are made with the possibility of conversion into Kalvelis hand springs for eliminate diastema. The lower base plate 2 contains two clasps 9 on the 6th teeth welded into the base plate, M-shaped hooks 13 for elastic rods 7 made in the form of rubber rings, and the vestibular arch 12.

Rods 7 connect the upper 1 and lower 2 base plates in a single design, which simultaneously has a therapeutic effect on the upper and lower jaws. The base plates 1 and 2 are made with the possibility of drilling holes for the growth of new teeth in them, for example, the second lateral upper incisors. Occlusive pads in the area of the 6th teeth on the upper plate divide the bite to extend the upper incisors mesially.

The proposed multifunctional double-jaw orthodontic apparatus-prosthesis for the treatment of mesial occlusion is used in dental practice as follows. If a patient with a mesial bite of milk chewing teeth is absent (usually in the absence of at least 10 teeth), the upper 1 and lower 2 base removable plates with artificial chewing teeth 3 and 4, clasps, hooks, protectors (Kalvelis hand springs) and other elements are made described above. Then, the manufactured removable prostheses are installed with the help of clasps 5 and 9 on the upper and lower jaws and put on elastic rods 7 on the M-shaped hooks 13 on the lower jaw and on the hooks 6 on the upper jaw, thereby connecting the base plates 1 and 2 into a single apparatus prosthesis. In this case, artificial teeth 3 and 4 provide the patient with the opportunity to chew food, the tractors 8 provide the advancement of the incisors, after which the protectors are converted into Kalvelis hand-springs to eliminate diastema in the area of the first teeth and create a place for the eruption of the second teeth. Lipsticks 10 push the upper lip, provide the extension of the upper jaw mesial, improve aesthetics, facial profile. Occlusive pads on the upper plate divide the occlusion in the area of chewing teeth. After removing the upper incisors from the back overlap, the occlusal overlays are removed.

The proposed prosthetic apparatus, when worn for 1.5-3 years, provides optimal growth in the TMJ joints, prevents mesial displacement of teeth in a mixed bite on the lower jaw. It is necessary to wear the proposed prosthetic device 24 hours a day, removing for hygienic care, the elastic traction 7 should be changed every other day. The multifunctional double-jaw prosthesis is especially effective in case of horizontal type of jaw growth, reverse incisal overlap, sagittal fissure greater than 1.0 mm, upper jaw underdevelopment, with early and multiple removal of temporary (milk) teeth, to normalize the incisor angle (/ _132 ± 10 * ), in a mixed bite in children 6-8 years old. Base plates 1 and 2 are made with the possibility of drilling holes in them for eruption of permanent teeth instead of milk teeth. If necessary, the prosthetic device is changed to a new one after 4-6 months.

Example No. 1. Patient M., age 7 years 10 months, turned to the clinic with complaints of protruding lower jaw forward, reverse incisal overlap, the presence of a gap between the upper incisors, the absence of temporary chewing teeth.
