UA15673U - Dentistry demonstration phantom - Google Patents

Abstract

The dentistry demonstration phantom contains the base of the model, which is made as one-piece with the pink imitators of gums comprising the artificial teeth. In the frontal translucent part of the phantom, the conical sockets are mounted in the imitators of gums for the screwed implants. The gum imitator is made of the transparent ceramics. The heads of the screwed implants are covered with the removable bridge metal-ceramic denture. The all-ceramic denture is installed onto the lateral prepared teeth. On the left, the prepared tooth is installed with the ledge for the recovery construction of the denture. The teeth and the roots are made of the ceramic dentistry materials.

Description

Description of the invention

The useful model refers to the field of medicine, namely dentistry, and can be used in the 2 learning process as a dental phantom of the human dentition-maxillofacial system.

The development of dental phantoms is gaining the greatest relevance due to the lack of opportunity for students to practice practical skills on patients, the need to demonstrate to patients all the possibilities of modern dentistry. The introduction of insurance medicine, the introduction of changes in the medical legislation requires a complete explanation and 70 demonstration of the shortcomings and advantages of the future design, which will be installed on the patient, from a modern orthopedist-dentist before prosthetics for the patient.

There are a large number of dental phantoms. The vast majority of them are aimed at training students of dental faculties and dentists in certain dental manipulations. That is why, for the purpose of preparation, endodontic procedures, the crown parts of the teeth are made of relatively soft substances, for example, plastic (1|Й1. The reproduction of artificial teeth in plastic does not reflect the full 72 anatomical picture of the tissues of the teeth and quite remotely resembles the maxillofacial system |2 )|. Such phantoms are quickly destroyed during operation. Some phantoms (C), made of strong materials (composite structural mixtures), have a transparent gingival part, but are intended only for certain limited manipulations, for example, endodontic treatment.

The closest to the proposed technical solution is the operating phantom produced by the company "Zagadoza" (4). The phantom consists of a model base, monolithically connected to the gingival part, made of composite, which has a pink color and is transparent in the frontal area. On the gingival part artificial teeth made of plastic are reinforced, and in the frontal transparent area, conical holes for screw implants are installed in the thickness of the composite, on the heads of which are installed caps for an orthopedic structure. With the help of the holes on the phantom, the skills of implanting dental implants are practiced, thanks to the transparent part, the position of the implants in the jaw is controlled in

However, this device has a strictly limited range of functions. This phantom is intended for implantological procedures only; due to the use of plastic and composite, it has a limited useful life - the introduction of screw implants destroys the hole after a certain number of procedures. In addition, the phantom does not reproduce orthopedic manipulations - there is no covering structure, which prevents the training of implantological procedures by dentists-orthopaedists. -

The basis of a useful model is the task of developing the optimal design of a dental demonstration phantom, which contains the gingival part of the model made of transparent ceramics, and on the heads of the screw implants, a one-piece combined metal-ceramic prosthesis is made, which will allow you to achieve long-term use of the phantom and bring it as close as possible to the anatomical and physiological 3 about the structure of the maxillofacial system. --

The task is solved by the fact that, according to the useful model, the gingival part of the model is made of transparent ceramics along the entire model, a removable bridge-like metal-ceramic prosthesis is made on the heads of the screw implants (5), and an all-ceramic "prosthesis" is made on the lateral prepared teeth on the right side (4 ), on the left - prepared a tooth with an abutment for a restorative structure (6), while all teeth and their Z 50 roots are made of ceramic dental masses. c Fig. 1, 2 shows the general view of the proposed phantom, where:

From" 1 - model base; 2 - gingival part of the model;

C - screw implant in the hole; 4 - one-piece bridge prosthesis; - 5 - metal-ceramic bridge prosthesis fixed on implants; 4! 6 - demonstration of a prepared tooth with a ledge for restoration.

The device is made like the models of jaws used in the practice of orthopedic dentistry from plaster of paris. But the phantom has a transparent plinth of the model, screw implants on which a bridge-like prosthesis is fixed. -and 20 The device is used as follows. In the first clinical variant, the phantom serves to explain to the patient the possibilities of prosthetics and to demonstrate the disadvantages and advantages of the structures shown to him. Phantom c" in assembled form (the upper part is shown in Fig. 1) is shown to the patient during the interview before the final choice of the orthopedic design of the fixed prosthesis.

In the second educational option, the phantom serves as a model for teaching students and doctors to carry out implantological, 29 orthopedic manipulations. That is, when the student is asked to make structures on a phantom, he has the opportunity to take impressions, make corrections of superstructures with fixation on implants. These manipulations can be compared with the finished work, which serves as a sample in this case.

In addition, long-term use of the dental demonstration phantom is possible. With certain changes (appearance of new improved technologies), the phantom can be improved (make additional 60 more complex orthopedic designs, replacing already made ones), by adding new designs to free areas of the model.

With the help of such a demonstration dental phantom, three important tasks that arise when working with other similar phantoms are solved: - the phantom has a long service life, thanks to the execution of all parts from dental ceramics, this gives the phantom the most complete imitation of the maxillofacial system; because the phantom is multifunctional, because it can be used both in medical and educational processes, in addition, one phantom contains a demonstration of several fixed structures of dental prostheses.
