EA035629B1 - Method of intermaxillary fixation at mandibular fractures - Google Patents

Abstract

The invention relates to medicine, in particular, to methods of intermaxillary fixation. According to the method of intermaxillary fixation, splints (mouth guards) are fixed to each other by a rubber rod. Cast models are taken from both jaws, after which splints of about 1 mm thick are made from ethylene vinyl acetate to cover the tooth range and 4-6 mm of the mucous membrane of the alveolar process, then 4-6 stainless steel or titanium orthodontic buttons with a mushroom head 2.5-3.0 mm in diameter and a 2 mm thick neck are attached to each splint; then the produced splints are applied to the upper and lower jaws, and intermaxillary fixation is performed. A high functional and aesthetic result of the treatment method is provided.

Description

Technology area

The invention relates to medicine, in particular to methods of intermaxillary fixation.

State of the art

Currently, many methods of intermaxillary fixation are known. The most common method is Vasiliev's splints, a standard 0.26-0.28 mm thick stainless steel belt strip with hook loops. It is bent along the dentition manually and is fixed on the teeth with a bronze-aluminum wire. Intermaxillary fixation is carried out using a rubber traction (Yu.M. Pogosyan, A.Yu. Poghosyan, A.Yu. Papyan // Injuries of the ChLO. Study guide 2010, 92-93). Despite this, tape splints have a number of disadvantages: oral hygiene is impaired; during fixation and later, wire splints injure the soft tissues of the oral cavity (gums, mucous membrane of the lips and cheeks), prompting the formation of numerous aftas. After removal of splints, atrophy of the intermaxillary papillae, resorption of interdental septa, varying degrees of tooth mobility, the formation of plaque and calculus are noticeable. The state of intermaxillary physiological rest is also disturbed.

Disclosure of invention

The objective of the proposed method is to create such a method of intermaxillary fixation, which will not have the above disadvantages, but will provide a high functional and aesthetic result.

The essence of the invention lies in the fact that the tires (mouthguards) are fixed to each other with a rubber traction. Impressions are taken from both jaws, after which splints with a thickness of about 1 mm are made from ethylene vinyl acetate, which cover the dentition and 4-6 mm of the mucous membrane of the alveolar process. Then, 4-6 orthodontic buttons made of stainless steel or titanium with a mushroom head with a diameter of 2.5-3.0 mm and a neck with a thickness of 2 mm are attached to each splint, after which the manufactured splints are applied to the upper and lower jaws.

Intermaxillary fixation using the proposed method and the achievement of the technical result are illustrated by examples of specific performance.

Implementation of the invention

Clinical example 1.

Patient A., 30 years old, was admitted to the University Hospital. Heratsi with a right-sided fracture of the lower jaw with displacement. Under general nasotracheal anesthesia, the 48th tooth was removed, which was located in the area of the fracture. The wound was closed tightly. Osteosynthesis with a titanium mini-plate was performed using an external approach. The wound was treated with an antiseptic solution, drained and sutured with interrupted sutures.

After, by the above method, impressions were taken from both jaws and sent to the laboratory for the manufacture of splints (splints). The next day, the aligners were put on the dentition and fixed between themselves with a rubber rod.

Clinical example 2.

Patient B., 21 years old, was admitted to MC Astghik with a left-sided fracture of the mandibular branch without displacement.

After taking the impressions and preparing the aligners, the latter were put on the dentition and fixed between themselves with a rubber rod.

The above method was applied in ninety-six patients with various fractures of the mandible. Complications after splinting were not identified.

Claims (1)

CLAIM The method of intermaxillary fixation in case of fractures of the lower jaw, including fixing the tires between each other with a rubber traction, is distinguished by the fact that impressions are made from both jaws, after which the tires are made of ethylene vinyl acetate with a thickness of about 1 mm, which cover the dentition and 4-6 mm of the alveolar mucosa. process, then 46 orthodontic buttons made of stainless steel or titanium with a mushroom head with a diameter of 2.5-3.0 mm and a neck with a thickness of 2 mm are attached to each splint, after which the manufactured splints are applied to the upper and lower jaws and intermaxillary fixation is performed.
