RU115644U1 - DEVICE FOR TREATMENT OF JAW FRACTURES - Google Patents

Abstract

A device for the treatment of jaw fractures, containing titanium flat splints with hook hooks placed on the upper and lower jaws, connected by an intermaxillary elastic traction, characterized in that the titanium flat splints have holes through which they are fixed on intraosseous screw implants with internal thread by screws - clamps.

Description

The utility model relates to medicine, namely to maxillofacial surgery, and can be used in the treatment of jaw fractures.

A device is known for immobilizing jaw fragments using Vasiliev, Tigerstedt tooth splints or standard wire splints, which are located on the teeth of the upper and lower jaws and are fixed using wire ligatures that circle around the neck of the teeth. Tire hooks are used for intermaxillary elastic traction. Thereby, immobilization and reposition of jaw fragments is achieved (Malyshev V.A., Kabakov B.D. Jaw fractures. - St. Petersburg: Speclit. 2005. - 48 p.).

The disadvantage of tooth tires is the damage to periodontal, tooth enamel, the inability to conduct good oral hygiene, the risk of periodontal disease. In addition, the use of this method is not always possible with severe or complete secondary adentia.

The purpose of the utility model is to eliminate complications caused by the use of tooth splints, to ensure adequate reposition, rigid fixation of jaw fragments, which is carried out by means of a firm connection in the form of an arch of intraosseous screw implants with a flat titanium splint, to maintain adequate oral hygiene by creating rinsing spaces between the splint and mucosa the shell of the oral cavity, to avoid injury to the periodontal teeth, which is achieved by the absence of tire pressure on the tooth enamel and the mucous membrane of the oral cavity, use in patients with severe or complete secondary edentulous, since the tire is not fixed to the teeth, and vnutrikostyh helical implants.

The goal is achieved by the fact that titanium flat tires with hook hooks have holes through which they are fixed on intraosseous screw implants with internal thread with fixing screws. In turn, intraosseous screw implants have a mucosal part, due to which there is no direct fit of the titanium flat splint to the oral mucosa. The hook hooks of the device are used for intermaxillary elastic traction.

Figure 1 presents a General view of the device.

The device contains 2 titanium flat tires (1) with hook hooks (2) and holes (3), intraosseous screw implants with internal thread (4) and fixing screws (5) that fix the titanium flat tire (1) through the holes (3 ) on intraosseous screw implants with internal thread (4). Hook hooks (2) are used for intermaxillary elastic traction (6).

The device operates as follows.

Intraosseous screw implants with internal thread (4) are inserted into the upper and lower jaws (at least 4 units for each of the jaws). Then reposition of fragments of the jaw. Flat titanium tires (1) are modeled on the shape of the jaws and fixed through the holes (3) with fixing screws (5) on intraosseous screw implants with internal thread (4). The hook hooks (2) are used for intermaxillary elastic traction (6) of the jaws in the position of the usual bite.

The number of installed intraosseous screw implants with internal thread and fixing screws depends on the location and nature of the fracture of the jaw. The device can be used in patients with severe or complete secondary edentulous. In addition, under certain conditions, it becomes possible to conduct extra focal intraoral osteosynthesis.

The operation of the device is illustrated by the following clinical examples.

1. Patient E. was taken to emergency room on an emergency basis. Clinically, radiologically examined, the diagnosis was established: a fracture of the lower jaw in the left condylar process and 43, 44 teeth. After performing anesthesia with a 2% solution of lidocaine of the alveolar process of the upper jaw, 4 bone beds were formed between the 14th, 15th, 12th and 13th, 22nd, 23rd, 24th and 25th teeth, 4 intraosseous screw implants with internal thread were installed, on which an individually fitted titanium flat splint was fixed with hooks and screws. After performing anesthesia on the lower jaw with a 2% lidocaine solution, 5 holes were drilled between 45 and 46, 44 and 45, 42 and 43, 32 and 33, 34 and 35, 5 intraosseous screw implants with internal thread were installed, 44 tooth was removed from the fracture gap, the fragments are repaired by a titanium flat tire and fixing screws. An intermaxillary rubber traction was applied, the teeth are fixed in the position of the usual bite. A plaster parietal chin dressing was made. At the end of the operation, the patient was hospitalized in the Department of ChLH. In the postoperative period, antibacterial, anti-inflammatory, analgesic therapy is prescribed. On the control radiographs, the position of the fragments is correct. Familiar bite.

The patient was observed on an outpatient basis for the entire period of immobilization of 4 weeks.

The postoperative period without complications.

At the control examination after 1 month malocclusion was not detected.

2. Patient G. was taken to emergency room on an emergency basis. Clinically examined, radiological, the diagnosis was established: fracture of the lower jaw in the region of 38 and 42, 43 teeth. After performing anesthesia with a 2% solution of lidocaine of the upper alveolar ridge, 4 bone beds were formed between 14 and 15, 12 and 13, 22 and 23, 24 and 25 teeth, 4 intraosseous screw implants with internal thread were installed, on which an individually fitted flat tire with hooks was fixed hooks with fixing screws. After performing anesthesia on the lower jaw with a 2% lidocaine solution, 4 holes were drilled between 45 and 46, 44 and 43, 32 and 33, 34 and 35, 4 intraosseous screw implants with internal thread were installed, 38 tooth was removed from the fracture gap, the fragments were repaired connected by a flat bus and fixing screws. An intermaxillary rubber traction was applied, fragments of the lower jaw in the region of the 38 tooth were repaired under visual control, the teeth were fixed in the position of the usual bite. Achieved stability of fragments of the lower jaw. A plaster parietal chin dressing was made. At the end of the operation, the patient was hospitalized in the Department of ChLH. In the postoperative period, antibacterial, anti-inflammatory, analgesic therapy is prescribed. On the control radiographs, the position of the fragments is correct. Familiar bite. There is no paresthesia in the innervation zone of the left mandibular nerve.

The patient was observed on an outpatient basis for the entire period of immobilization of 4 weeks.

At the control examination after 1 month malocclusion was not detected.

The claimed device was installed to 45 patients aged 18 to 45 years for 6 months. All patients underwent adequate oral hygiene during treatment, a periodontal trauma was avoided, and fragments were consolidated within 4 weeks, which allows this device to be recognized as effective and safe.

Using the proposed device avoids the trauma of periodontal teeth, to ensure adequate reposition, reliable fixation of jaw fragments, maintain adequate oral hygiene. In addition, the use of this device is possible with severe or complete secondary adentia.
