RU2316286C1 - Method for forming functional design of individual spoons - Google Patents

Abstract

FIELD: medicine.

SUBSTANCE: method involves fitting individual spoon, holding it on jaw, modeling individual spoon edges with thermoplastic mass. Fixing inlays are placed on the internal surface of individual spoon having occlusion rollers. The inlays are arranged over alveolar process bed and along the posterior one-third of palatine on the upper individual spoon, whereas the lower individual spoon is spread along the alveolar process bed. The fixing inlay is supposed to be 0.2-0.3 mm far from individual spoon edge. Next to it, thermoplastic mass is drawn along individual spoon edge and the spoon is inserted into the oral cavity. Functional tests are done under pressure exerted by chewers under dentist control.

EFFECT: high maxillary and mandibular spoon model design quality; easiness in operation; accelerated operation process.

Description

The method relates to medicine, namely to orthopedic dentistry, and is intended for the functional design of the edge of an individual spoon used to obtain an impression in the complete absence of teeth.

There is a method of functional design of the edge of individual spoons using a device that fixes an individual spoon on the toothless lower jaw, consisting of an individual spoon, on the upper surface of which there are stops with holes for fixing the upper ends of the elastic element, as well as from the chin sling equipped with an element in which the movable lower ends of the elastic element are mounted (M.L. Zaxon, G.D.Ovrutsky, M.I. Pyasetskiy, A.M. Solntsev. Practical gerontostomatology and geriatrics. - Kiev: Health, 1993. - P. 241 -245).

The disadvantages of this method are the complexity of the device, the need for special preparation of an individual spoon, as well as the uncontrolled pressure of the device on the mucous membrane of the prosthetic bed. This device cannot be used for the functional design of the edge of the upper individual spoon.

The technical result of the invention is to improve the quality of the functional design of the edge of an individual spoon of both the upper and lower jaw under chewing pressure, the convenience of the doctor, as well as reducing the time spent on this manipulation.

The technical result is achieved by the fact that to hold the individual spoon on the toothless jaws, the functional design of the edge uses fixing pads, for example Fitty Dent “Comfort” (FITTYDENT INTERNATIONAL GMBH Pinkafeld, Austria) and the pressure on the individual spoon is produced by the strength of the chewing muscles.

The way to design the edge of an individual spoon is illustrated with graphic material. The figure 1 shows the upper individual spoon 2 with an occlusal roller 1, edged with a thermoplastic mass 5 and with the applied fixing pads 3; figure 2 - lower individual spoon 2 with retaining pads 3; in figure 3 - the lower individual spoon in a cross section, where 1 is an occlusal roller; 2 - an individual spoon; 3 - fixing gasket; 4 - alveolar bone; 5 - thermoplastic mass along the edge of an individual spoon.

The proposed method is used as follows. Fixing pads 3 are laid on the inner surface of an individual spoon 2 with occlusal rollers 1 that has been functionalized using functional tests. Laying pads 3 are placed on the upper individual spoon (Fig. 1) and along the back third of the palate 3, on the lower individual spoon (Fig. 2) ) the gasket is placed on the bed of the alveolar ridge 3. The fixing gasket should not reach the edge of the individual spoon by 0.2-0.3 cm. Next, the thermoplastic mass 5 is applied along the edge of the individual spoons and the spoons are placed in the polo mouth mouth. The patient closes the jaw and performs functional tests under the supervision of a physician.

Fixing pads hold individual spoons on the jaws, allowing the functional design of the edge of both the upper and lower individual spoons with a thermoplastic mass with a greater amplitude of movement of the lower jaw. The maximum pressure on individual spoons produced by the strength of the masticatory muscles is more rational.

Using the proposed method improves the quality of the functional design of the edge of both the upper and lower individual spoons, and also reduces the time spent on this manipulation.

The proposed method was used for the functional design of the edge of an individual spoon of both the upper and lower jaws when prosthetics of 15 patients with complete absence of teeth. The results are good.

Claims (1)

The method of functional design of the edge of an individual spoon, including fitting an individual spoon, keeping it on the jaw, forming the edges of an individual spoon with a thermoplastic mass, characterized in that fixing pads are placed on the inner surface of the individual spoon with occlusal rollers, and the alveolar bed is placed on the upper individual spoon of the spacer of the process and along the posterior third of the palate, and on the lower individual spoon, the spacer is placed along the bed of the alveolar process, while the fixing pad should not reach the edge of the individual spoon by 0.2-0.3 mm, then a thermoplastic mass is applied along the edge of the individual spoon and the spoon is placed in the oral cavity, functional tests are performed under the pressure of the chewing muscles and the doctor’s control.
