Length measurement model for root canal of isolated tooth and measurement method of length measurement model

Abstract

The invention discloses a length measurement model for a root canal of an isolated tooth and a measurement method of the length measurement model. According to the length measurement model and the measurement method, the technical problems that existing length measurement teaching of the root canal of the isolated tooth is low in simulation degree and is disjointed from practical clinic in the prior art are solved. The length measurement model comprises a base model and a tooth model, wherein an isolated tooth embedding slot is formed in the tooth model, and a conducting gel block and a metalring are arranged in the base model; and when a to-be-measured isolated tooth is embedded into the isolated tooth embedding slot, the tip of the to-be-measured isolated tooth is located in the conducting gel block, one end of the metal ring is located in the conducting gel block, the other end of the metal ring is located out of the base model. According to the measurement method, the length of the root canal is measured by virtue of a root measurement instrument, and the root measurement instrument is connected with a root canal file and the metal ring through two leads. The length of the root canal of the isolated tooth mounted in the measurement model on a head-simulated model is measured by virtue of the root measurement instrument, so that a teaching scene is basically accordant withpractical clinic root canal length measurement scene, the simulation level of the teaching is increased, and the teaching is closer to the clinical practice and is more vivid and practical.

Description

technical field [0001] The invention belongs to the technical field of tooth root canal length measurement, and in particular relates to a measurement model and a measurement method for the length of an isolated tooth root canal. Background technique [0002] Root canal therapy (root canal therapy) is a universal and effective treatment method recognized at home and abroad for pulp disease and periapical disease. The principle of root canal therapy is to remove most of the infected substances in the root canal through mechanical and chemical methods, and to seal the root canal tightly by filling the root canal, so as to prevent the occurrence of periapical lesions or promote the healing of periapical lesions that have occurred. [0003] In the process of root canal treatment, measuring the root canal length of the affected tooth is an essential procedure. The existing tooth root canal length measurement generally uses a root canal length measuring instrument, also called an ...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a measurement model of the root canal length of an isolated tooth and its measurement method, so as to solve the problem of using a root tester to simulate the clinical operation process to measure the root canal length of an isolated tooth during the teaching of the prior art. The technical problem that leads to the low degree of teaching simulation, which leads to the disconnection between teaching practice and actual clinical operation
