Description

Technical Field

[0001] The invention relates to the technical field of oral medicine, and in particular to a practice bracket for oral medicine operation. Background Art

[0002] Dentistry mainly studies the basic knowledge and skills in the diagnosis, treatment and prevention of oral and maxillofacial diseases, and conducts diagnosis, treatment, restoration and preventive health care of common and frequently occurring oral diseases. Dental students need a lot of practice in practical classes and before practical examinations, such as: oral anesthesia, tooth extraction, intraoral suturing, tooth cavity preparation, crown restoration preparation, etc.

[0003] Currently, most medical students only use a single jaw to practice oral operations. However, the actual situation is that the operating space in the patient's mouth is limited when the patient's mouth is open. At the same time, saliva is constantly secreted inside the mouth, which causes doctors to be affected by various factors when performing oral operations. It is difficult to achieve real results through training with a separate jaw model. Therefore, a practice stand for oral medical operations is proposed to simulate the real oral environment and improve the operation skills through practice. Summary of the invention

[0046] Working principle: The user holds the oral rapid handpiece to adjust and prepare the tooth 3, and can practice tooth cavity preparation and crown restoration preparation. When extracting a tooth, the user first separates the gums around the tooth 3, and extracts the tooth 3 from the grooves on the surface of the upper jaw 2 and the lower jaw 4 using tools such as tooth extraction forceps or tooth collars. When suturing, the user cuts the silicone mucosa with a surgical blade to simulate a wound.
