UA27954U - Method for making of complete removable denture on lower jaw - Google Patents

Abstract

A method for making of complete removable denture on a lower jaw is carried out by conventional technology. After denture correction in a clinic in the area of corunculum sublingvale a plastic is removed from acryl base by the bone cutter within 2-3 cm from a cutting edge and 2-3 retentional points are made. After that formed defect is reproduced by the base wax plate, elastic plastic of Mucopren soft is prepared, a wax plate is covered with a layer of 2-3 mm thickness at the oute side with ceiling of acryl base on 5-10 mm, in 10 mines the denture is washed with hot water for wax removing, polished and placed on a prosthetic bed.

Description

Description of the invention

The useful model belongs to medicine, namely to dentistry, and can be used in orthopedic 2 dentistry in the manufacture of complete removable lamellar prostheses for the lower jaw in case of traumatic sialoadenitis.

A significant number of people who use prostheses suffer from traumatic sialoadenitis. The cause of this disease is the peculiarities of the anatomical structure of the lower jaw, the submandibular salivary gland and its ducts |11.

The disease is caused by dental prostheses, in the manufacture of which the indicated anatomical 70 features are not taken into account.

Very few scientific works are devoted to the study of this problem. Even the scientific term "rheumatic sialoadenitis" was introduced into dentistry quite recently |2|.

Prosthetics of patients with a complete absence of teeth on the lower jaw, who suffer from sialoadenitis, is a difficult problem, because the edge of a rigid acrylic prosthesis injures the submandibular gland and leads 19 to the complication of the course of traumatic sialoadenitis. That is why the development of the design of a complete removable dental prosthesis for the lower jaw acquires the greatest relevance.

The closest to the proposed technical solution is a removable dental prosthesis for the edentulous lower jaw (IZ). It represents a dental prosthesis containing artificial teeth and a combined plastic base, in which the layer of the combined base, which directly touches the mucous membrane of the prosthetic bed, is made of elastic plastic behind the relief impression, and the base layer is made of hard plastic, facing the tissues of the prosthetic bed, made according to a compression impression, while the layer of elastic plastic of the prosthesis of the upper jaw in the area of the back third of the palate is made with a descent to the minimum thickness.

However, such a prosthesis needs to be replaced every six months due to the tendency of the elastic lining to wear out. When performing the prosthesis, the special anatomical position of the salivary gland is not taken into account.

The basis of a useful model is the task of developing an optimal design of a complete removable prosthesis for the) lower jaw, which contains artificial teeth and a combined plastic base.

The task is solved by the fact that the complete removable prosthesis for the lower jaw in the area of the sublingual ridges contains patterns filled with elastic plastic for clinical re-base, which is superimposed on a layer of acrylic base 2 mm thick, overlapping the base by 5-10 mm. WITH

A useful model is used as follows. oh

The prosthesis is made using traditional technology. After the correction of the prosthesis in the clinic in the area of the hyoid ridges (gypsum plaster of paris) 2 cm to the front level in the acrylic base, plastic is selected with a milling cutter and 2-3 retention points are created, then the created defect is reproduced with a plate of base wax, prepare /- I use Mysorgep elastic plastic, cover a layer of 2-3mm wax plate on the outside with an overlap of 5-10mm acrylic base, after 100 minutes wash the prosthesis from the wax with hot water, polish it and put on the prosthetic bed.

With the help of such a complete removable prosthesis, three important clinical problems are solved that arise during the manufacture of other complete removable prostheses when the complete absence of teeth on the lower jaw is complicated by "traumatic sialoadenitis (prototype): With 70 - the proposed prosthesis is made at the last clinical stage by a doctor, which makes it possible c completely eliminate the traumatic etiological factor on the salivary gland;

With" - due to the absence of elastic plastic on the entire surface of the base, there are no problems with overbite and the need to replace the prosthesis every 6 months; - due to the use of Mysorgep plastic, the fixation of the prosthesis is not disturbed, as the valve zone is not interrupted. o Literature: -I 1.

Claims (1)

The formula of the invention is the method of manufacturing a complete removable dental prosthesis for the lower jaw, which consists in the fact that the prosthesis is manufactured according to traditional technology, which differs in that after the correction of the prosthesis in the clinic, in the area of the hyoid ridges (sogypsciSht zibBiipodmaie) by 2-3 cm to the front edge of the acrylic base, plastic is selected with a milling cutter and 2-3 retention points are created, then the created defect is reproduced with a 60 plate of base wax, elastic plastic Mysorgep zoi is prepared, the wax plate is covered with a layer of 2-3 mm from the outside, overlapping the acrylic base by 5-10 mm , after 10 min. the prosthesis is washed from wax with hot water, polished and placed on the prosthetic bed.
