RU161475U1 - TRAINING MODEL OF HUMAN Upper Jaw for Endodontic Treatment and Teeth-Preserving Operations of Multi-Root Teeth - Google Patents

Abstract

A training model of the human upper jaw for endodontic treatment and tooth-preserving operations of multi-rooted teeth, which is a gypsum cast, in which small and large natural multi-rooted teeth are located in the left and right parts of the upper jaw in the alveolar ridge, with carious defects, pulpal cavities and root canals cavities filled with a rubber reservoir with colored liquid are made in the area of her body.

Description

The utility model relates to medicine, namely to therapeutic, surgical dentistry and can be used as a teaching aid for performing endodontic treatment on the teeth of the upper jaw, as well as tooth preserving operations, such as resection of the apex of the tooth root, hemisection, amputation of the root of the multi-rooted teeth.

Currently, domestic and foreign educational models for studying the anatomical structure of the upper jaw are known. For example, the MEDIUS Company (website www.MEDIUS.RU) produces anatomical training models made of AKP-7 plastic (catalog Medical aids and simulators. OJSC "MEDIUS". Medicine. Osteological models made of plastic. P5, P. 13).

These training models do not allow practicing tooth-preserving operations on the upper jaw, as well as endodontic treatment of small and large multi-rooted teeth due to the absence of carious defects, pulp cavities, root canals of multi-rooted teeth, and the maxillary sinus. The disadvantages of the above working models include the mismatch of the polymer material with the anatomical structure of the teeth of the upper jaw.

In the available literature, we did not find information about the training model intended for teaching endodontic treatment and conducting tooth-preserving operations of multi-rooted teeth.

The objective of the utility model is to develop the necessary conditioned reflexes and natural tactile sensations in students during endodontic training, as well as tooth-preserving operations of multirooted human upper jaw teeth.

The technical result of the claimed utility model is the development of a training model of the human upper jaw for endodontic treatment and tooth-preserving operations of multi-rooted teeth with an individual anatomical location of the roots of multi-rooted teeth with carious defects, pulpal cavities and root canals, as well as the maxillary sinus.

The technical result of the claimed model is achieved by the fact that the educational model of the human upper jaw for endodontic treatment and tooth-preserving operations of multi-rooted teeth is a plaster cast, in which small and large natural ones with carious defects and pulpal cavities are located in the left and right parts of the upper jaw in the alveolar process and root canals with multi-root teeth, and in the area of her body, in the left and right parts, cavities are filled with a rubber reservoir with colored fluid awn.

The salient features of the claimed utility model and the causal relationship between them and the achieved technical result:

- The educational model of the human upper jaw for endodontic treatment and tooth-preserving operations of multi-rooted teeth is a plaster cast in which small and large natural multi-rooted teeth are located in the left and right parts of the upper jaw in the alveolar ridge, with carious defects, pulpal cavities and root canals.

The location of small and large natural ones with carious defects, pulpar cavities and root canals of multi-rooted teeth provides the development of practical skills necessary for endodontic treatment of small and large multi-rooted teeth.

- In the region of the left and right parts of the upper jaw of the body, cavities are filled with a rubber reservoir with colored liquid.

A rubber reservoir filling the cavities imitates the mucous membrane of the maxillary sinus.

The stained fluid filling the rubber reservoir simulates blood.

The presence of cavities in the body of the upper jaw allows you to bring endodontic treatment and surgical procedures performed on the training model closer to the clinical practice, since if the reservoir is damaged, the stained fluid simulating blood will enter the tooth canal, not allowing it to be filled, and when the apex is resected tooth root, hemisection, amputation of the tooth root will flow into the formed hole of the alveolar process.

In FIG. 1 shows a General view of the claimed utility model, where:

1. - small and large natural multi-rooted teeth with carious defects, pulpal cavities and root canals;

2. - alveolar bone;

3. - the upper jaw;

4. - cavities filled with a rubber reservoir;

5. - colored liquid.

For a better understanding of the essence of the device, we presented Fig. 2, where:

1. - small and large natural multi-rooted teeth with carious defects, pulpal cavities and root canals;

1a. - multi-root tooth after resection of the apex of the root of the tooth;

1b. - multi-root tooth after after hemisection;

1c. - a multi-root tooth after amputation of a tooth root.

2. - alveolar bone;

3. - the upper jaw;

4. - cavities filled with a rubber reservoir;

5. - colored liquid;

The utility model works as follows:

Endodontic treatment: Having fixed the training model of the upper jaw in the phantom of the head, a carious defect and the pulp cavity of one of the multi-rooted teeth (1) located in the alveolar process (2) of the upper jaw (3) are prepared. The length of the tooth roots is determined so that during the endodontic treatment of this tooth, the cavities filled with a rubber reservoir (4) with colored liquid (5) are not damaged. Endodontic treatment is completed by replacing the formed cavity after preparation of a carious defect, pulp cavity and root canals of a multi-root tooth with filling material.

Dental preservation operations performed after endodontic treatment:

Root apex resection:

The buccal part of the alveolar bone (2) is removed by boron to the apex of the tooth root. The apex of the tooth root is resected with fissure boron in the case when it was not possible to seal the canal of a multi-root tooth (1). The root canal of a multi-root tooth (1) is expanded and retrograde filled. A multi-root tooth after resection of the apex of the root of the tooth (1a) is shown in FIG. 2.

Hemisection:

Hemisection (dissection) of the tooth crown is carried out in the case when it was not possible to seal the canal of a multi-root tooth (1). Then half the crown of the multi-root tooth (1) is removed along with the root of the multi-root tooth (1). A multi-root tooth after hemisection (1b) is shown in FIG. 2.

Amputations of the tooth root of multi-rooted teeth:

In the event that the root canal of the multi-root tooth (1) could not be sealed, the tooth root amputation operation is performed using diamond discs or diamond burs. First, the buccal part of the alveolar process (2) of the upper jaw is removed, then only the tooth root is removed. A multi-root tooth after amputation of a tooth root (1c) is depicted in FIG. 2.

The traumatic performance of both endodontic treatment and tooth-preserving operations leads to damage to the cavities filled with a rubber reservoir (4), which performs the function of the maxillary sinus, which causes the colored fluid to leak out of the rubber reservoir (4) (5).

Thus, for the first time, a training model of the human upper jaw has been developed for endodontic treatment and tooth-preserving operations of multi-rooted teeth with an individual anatomical location of the roots of multi-rooted teeth with carious defects, pulpal cavities and root canals, as well as the maxillary sinus, which allows students to develop the necessary conditioned natural tactile reflexes sensations during endodontic preparation, as well as tooth-preserving operations of multi-rooted teeth.
