Description

The utility model relates to the field of medicine - dentistry and can be used to study and master the methods of conductor methods for anesthesia of the mandibular nerve.

In an outpatient setting for the treatment of dental diseases, the most effective and safe method of pain relief is local anesthesia. Currently, it is used in 98-99% of cases (S.A. Rabinovich, E.V. Zoryan, S.T.Sokhov, and others. - From novocaine to articaine. - M., 2005). According to the data of the Dental Association of Russia, the appeal of the population to a dentist during the year is 150 ml. visits. The widespread introduction of local anesthesia in the treatment of dental diseases on an outpatient basis increases the availability and effectiveness of dental care.

During dental interventions on the upper jaw and in some clinical situations on the frontal region of the lower jaw, infiltration methods of pain relief are mainly performed. And on the lower jaw, due to the structural features of the bone tissue, conductive methods of anesthesia are used, which are technically more complex, which is associated with the anatomical features of this area.

The problem of safe and effective conductive anesthesia is one of the urgent problems in dentistry and is constantly in the field of view of specialists (NN Bazhanov, S. S. Ganina - Anesthesia in outpatient dental practice. - M., 1979; P.M. Egorov - Local anesthesia in dentistry. - Moscow, 1985; A.F. Bizyaev, S.Yu. Ivanov, A.V. Lepilin, S.A. Rabinovich - Anesthesia in the conditions of a dental clinic. - M., 2002; A.Zh. Petrikas - Anesthesia of teeth. - Tver, 1997; S.F. Gritsuk - Anesthesia in dentistry. - M., 1998; P.Yu. Stolyarenko - Sovreme nye local anesthesia technology

dentistry. - Samara, 1998; SA Rabinovich - Modern technologies of local anesthesia in dentistry. - M., 2000.).

There are more than 25 intraoral and approximately the same extraoral methods for conducting anesthesia of the mandibular nerve.

A disadvantage of many known methods is that they are focused on the average anatomical data regarding the structure of the lower jaw and the pterygo-mandibular space, in which the neurovascular bundle is located and the lower alveolar nerve passes. As a guideline for injecting an injection needle, it is suggested to use anatomical formations, which can be weakly expressed (pterygo-maxillary fold, temporal crest), or be completely absent, which complicates the implementation of conductive methods of anesthesia (S. A. Rabinovich - Modern technologies of local anesthesia in dentistry . - M., 2000).

In addition, there are age, individual, genetic and anatomical features of the height of the alveolar process and the degree of atrophy of the bone tissue of the lower jaw, the number and thickness of soft tissues adjacent to the lower jaw, which are not taken into account by the authors when describing the implementation of conductive methods of anesthesia. The foregoing and many years of clinical experience confirm that the average anatomical data do not always coincide with the anatomical ratios of a given patient, which makes it difficult to perform anesthesia and may be the reason for the lack of anesthetic effect and various complications, not only of a local nature, but also of somatic origin.

In the literature available to us, no information was found on devices that facilitate the mastery of conduction methods of injection analgesia, allowing to individualize the technique of anesthesia, accurately determine the point of injection of the needle, and accurately set the angle of the needle, both horizontally and vertically. Of analogs

The inventive device "Injection dental simulator" does not have.

Thus, practitioners with different levels of training and work experience today do not have a clear algorithm of actions when conducting the guide method of anesthesia in the lower jaw, taking into account the individual anatomical and age characteristics of the patient.

The inventive utility model is aimed at achieving a technical result - the acquisition and acquisition of skills for conducting conduction anesthesia to increase the safety and effectiveness of conduction anesthesia in the lower jaw.

The technical result achieved is achieved by using a simulator containing a cylindrical body for fixing the syringe with scales for measuring the depth of penetration of the needle into the tissue, the angle of rotation of the needle in horizontal and vertical planes, on which two occlusal plates are placed by means of springs.

The device allows you to:

- determine the injection point of the injection needle;

- fix on a predetermined position karpulny syringe;

- keep the lower jaw in position, due to the springs of the occlusal pads;

- determine the depth of penetration of the needle into the tissue;

- visualize the anesthetic area.

The utility model is illustrated by the following illustrations: figure 1 is a General view of a utility model facing the oral cavity in isometry; figure 2 is a General view of a utility model in isometry; figure 3 is a front view of a utility model; 4 is a side view of a utility model.

Description of the device - figure 1 shows a General view of the device, which consists of spring-loaded occlusal pads located on a cylindrical body 1 for fixing the syringe, with a scale of 2 for measuring the depth of penetration of the needle into the tissue, the tilt mechanism 3

needles in the vertical plane, scale 4 (with arrow) of the angle of rotation of the needle in the vertical plane, latch 5 arrows of the scale 4, mechanism 7 of rotation of the needle in the horizontal plane, scale 8 (with arrow and lock) of the angle of rotation of the needle in the horizontal plane, two occlusal plates 6 for teeth of the upper and lower jaw, two springs 9 connecting occlusal lining.

The utility model is used as follows: during the development and fixing of methods of conduction anesthesia in the lower jaw, the doctor asks the patient to open his mouth as much as possible, then the injection dental simulator is placed in the oral cavity, the patient is offered to have two occlusal linings with the front teeth of the upper and lower jaw 6. Carpool syringe placed in a cylindrical housing 1. Using scales 2, 4, 8, select the depth of penetration of the needle, the angle of inclination of the needle in the vertical and horizontal planes. The needle is inserted into the tissue according to the specified parameters - depth, angle of inclination in the horizontal and vertical planes and an anesthetic solution is injected. Then, the needle is removed from the tissues in the reverse order, after which the injection dental simulator is removed from the oral cavity and subjected to the usual sterilization technique.

With the help of an injection dental simulator, a practicing dentist with any preparation, a student of a medical university, intern, intern can form and consolidate manual skills, which will increase the efficiency of injection anesthesia in the lower jaw at the mandibular opening, while it is possible to master the methods of conduction anesthesia in the lower jaw, both on the phantom and during the reception of the patient. Injection dental simulator creates the necessary conditions for accurate and reliable fixation in the oral cavity of the syringe during injection pain relief. The device is made of a material resistant to physical and chemical influences and lends itself to all known sterilization methods.
