SU1743592A1 - Method for applying a dental splint - Google Patents

Abstract

Using; in medicine, namely in dentistry. The purpose of the invention is to increase the reliability of fixation of jaw fragments or mobile teeth during periodontal disease by accurately repeating the relief of the dental row by the splint. SUMMARY OF THE INVENTION: Before placing the tire, it is filled with a self-hardening plastic mass, and a polymeric tube made of biologically inert material with a diameter of 1.0-2.0 mm is used as the tire.

Description

The invention relates to medicine, to a section of a jaw injury.

The most frequently, in 50-96% of cases, for the treatment of fractures of the jaws, the method of out-labial splinting is used.

The advantages of out-of-laboratory splinting are the standardization, versatility, simplicity and speed of the procedure, and the disadvantages are the possibility of additional jaw injury when fitting the tires in the patient's oral cavity, their individuality is insufficient and, in the case of metal tires, the remaining permanently deformed condition is preserved. wire arc, striving to dislodge fragments, the possibility of the development of galvanoses.

The prototype of the invention is a method of applying a standard polyethylene tire.

Common features for the prototype and the proposed method are the use of a polyethylene arc as a means for fixing the fracture and the teeth as support points.

The disadvantage of the prototype is that the solid polyethylene tire does not have sufficient rigidity and resistance to elastic deformation, which leads to a decrease in the reliability of fixation of fragments. In addition, it does not have sufficient individuality when fitting in the mouth, which also impairs fixation.

The purpose of the invention is to increase the reliability of fixation of jaw fragments or mobile teeth during periodontal disease by accurately repeating the relief of the dental row by the splint.

The goal is achieved by using a thin-walled polyethylene tube with a diameter of 1.0-2.0 mm for single-jaw splinting, which is filled with freshly prepared self-hardening plastic (Protacryl-M, etc.) before the procedure from a single-use syringe.

Then the tube is shortened according to the length of the dental arch and is attached to each tooth with an ordinary ligature wire or polyamide thread. In this case, the ligatures should be tightened moderately so that they do not narrow the tube lumen by more than 1/2, i.e. so that the continuity of the plastic core of the tire is not broken.

Extruded plastic extruded from the ends of the tube is removed as the tire is pressed against the teeth.

In two-jaw splinting, the filling of each tube with plastic is carried out sequentially prior to fixation. In this case, the hooked hooks for maxillary stretching are made of stubs of ligature wire, the ends of the co-second are pulled out into the vestibule of the oral cavity and twisted.

After the polymerization is completed, the tire fits precisely to the crown of each tooth and completely repeats the arc surface of the tooth row.

At the same time, the tire has considerable rigidity and resistance to elastic deformations.

Thus, this method combines the advantages of both off-laboratory tires (versatility, simplicity and quickness of splinting), and laboratory structures (individuality, stability and rigidity of fixation). In addition, it lacks such disadvantages as the residual stress-strain state of the dental arch, in connection with the ductility of the tire at the time of its imposition, as well as the harmful effects of self-hardening plastic in connection with its insulation.

New in the proposed method is the use of a soft and elastic polymer shell with a core of self-hardening plastic for the manufacture of a tire, due to which there is a delayed increase in the stiffness of the tire after its individual fitting. At the same time, the non-laboratory tire made of a biologically inert polymer exactly repeats the individual tooth relief of the patient.

Example. Sick K., 31 years old. She was treated in the dental department of the Minsk Regional Children's Clinical Hospital from January 11, 1990, until January 22, 1990, with a diagnosis of a traumatic open single unilateral fracture.

the bodies of the mandible on the right are the areas 31 without displacement.

The fragments are fixed on January 11, 1990 using a smooth plastic tubular tire filled with Procaril-M, which is placed on the latching surface of the teeth. The tire is fixed to the teeth with ordinary ligature wire. The patient undergoes a course of physiotherapy. After 11 days, the patient is discharged for outpatient treatment. After 25 days, during re-inspection, the tire is removed, Fracture consolidation is confirmed clinically and osteometrically. Recommend: electric donor diagnostics 31.

In total, the proposed method successfully treated 4 patients. Clinical experience confirms its effectiveness and a number of undoubted advantages.

Thus, the proposed method makes it possible to copy the topography of the dental row and increase the rigidity of the tire, thereby providing a fixation strength of the fragments that is maximum possible for this type of tire.

The positive effect that is achieved due to the distinctive features of the proposed method cannot be achieved using a standard polyethylene tire, i.e. according to the method prototype.
