Description

fie. /

The invention relates to medicine, namely to surgical dentistry.

The purpose of the invention is to reduce trauma in the treatment of fractures in the region of the mandible angle due to the partial transfer of pressure to the teeth, as well as to prevent displacement of the tire along the tooth row during tension.

Figure 1 shows a device for fixing fragments of the mandible; figure 2 - key under the head of the bolt; on fig.Z - screwdriver with a slot on the working part.

The proposed device is detachable consists of a conical cap with an external screw thread, a threaded compression element and a tire-clip. A conical screw-on cap 1 ends with a tip and a head (stop) 2. At the end of the head there is a slot 3 (under a screwdriver) and an entrance to the blind channel 4 with internal left-hand thread. The threaded com-element 5 is made in the form of a rod with an external left-hand thread (for screwing into the deaf channel 4 of the conical cap) and hexagonal

tallic ligatures. Rotating with the key the head of the compression element 5 in a counterclockwise or counterclockwise direction, produces a metered compression or distraction of fragments. For simultaneous fixation of the cap 1, a slotted screwdriver is used. If it is necessary to act on the distal fragment of two forces: horizontal and vertical, rubber rings are used, which are fixed in the slot specially left for this between the cap 2 limiter and the compression element head, fixing them also on the upper jaw splint, thereby creating a uniform vertical load on fixed fragments of the lower jaw.

The use of maxillary extrusion is also possible, which is carried out with the help of double ligature hooks fixed to the splint and rubber rings. After complete consolidation of fragments, the splint and compression element are removed. The cap is left in the distal fragment of the mandible for the entire period.

head 6 (PD key), at the end of which the patient is monitored. If necessary, there is an entrance to the blind channel 7 with a right-hand thread. The busbar bar has grooves 8 and a right-hand thread at the end (for screwing into a blind channel with a right-hand thread).

The device is used as follows.

Under the infiltration and conduction anesthesia, an incision of up to 5 mm of the mucous membrane and periosteum 0 is made in the retromolar arch at the site of the planned insertion of the cap (the size of the incision corresponds to the diameter of the insertion sleeve). Using a direct stochasticity, reapply the rod, splint, create a metered compression or distraction of fragments.

The proposed device is simple in technical implementation, relatively atraumatic, due to the limited portion of the introduction of the sleeve and out-of-stage fixation. The tire makes it possible to put the fragments in the correct position, to fix them securely, to create a metered compression. The device can use a metrological tip and a bur (wrinkle with fractures with partial

lo) the required diameter, drill a hole in the branches of the lower jaw, fixing it with your hand. Using a screwdriver, screw the cap into this hole completely up to the stop of the head (limiter) 2. The core is partially screwed into the channel 4 of the cap. Then the end of the clamped brace is partially screwed into the channel at the end of the head of the compression element 5. The splint is bent over the dental row and fixed to mol with a ligature of anoxide steel with a diameter of 0.6-1 mm, and to the rest of the teeth with thinner 50 mm.

adentia, in most cases, the possibility of intermaxillary marriage. An integral part of the cap inserted into the distal fragment of the lower jaw can be there for a long time, the entire period of follow-up. repeated trauma, various complications of inflammatory etiology, the tire can be re-implanted again to the cap that already has it. The device can also be used for treating lower jaw progression by two-sided

patient monitoring. When necessary

mobility re-impose a rod, bus-bracket, create a metered compression or distraction of fragments.

The proposed device is simple in technical implementation, relatively atraumatic, due to the limited portion of the introduction of the sleeve and out-of-stage fixation. The tire makes it possible to put the fragments in the correct position, to fix them securely, to create a metered compression. The device can be attached to fractures with partial

adentia, in most cases excludes the possibility of intermaxillary stretching. An integral part of the device is a cap embedded in the distal fragment of the lower jaw, which can be there for a long time, the entire period of follow-up. In case of repeated trauma, various complications of inflammatory etiology, this tire can be re-applied and again fixed to the cap that already exists. The device can also be used to treat mandibular progression by bilateral osteotomy, it is easily sterilized and it is used many times.
