Advanced modular model for training dental operation hand feeling

Abstract

The invention provides an advanced modular model for training dental operation hand feeling, which comprises a model main body, a simulated enamel layer, a dentin layer, a dental pulp cavity layer and a transparent back plate layer from top to bottom in sequence, and is characterized in that the model main body is provided with a Sudoku structure; a linear training structure, a cross-shaped training structure, a circular training structure, a C-shaped training structure, a dovetail-shaped training structure and a circular triangular training structure are arranged on the Sudoku structure, and a blank area and two protruding surface simulation tooth tip form areas are further arranged on the Sudoku structure. The hand fine motion ability of students can be trained step by step, the three-dimensional feeling from the horizontal direction to the vertical direction and from the plane to the inclined plane with the tooth tips can be achieved, the fine feeling of the students applying the high-speed drill point to move in the model in the transverse direction, the longitudinal direction and the arc line under the stable fulcrum can be trained, and the fine feeling of gradually abrading and cutting different tissues of the tooth body and falling in the marrow penetrating process can be trained; therefore, the hand stability and flexibility of the student can be trained.

Description

technical field [0001] The invention belongs to the technical field of dental training models, and in particular relates to an advanced modular model for training dental operation feel. Background technique [0002] Dental operations require high-standard horizontal and vertical fine movements. At present, the teaching system of stomatology usually starts to use skull models to simulate teeth for hand high-speed turbine fine motor exercises in the fourth grade of undergraduates. However, this teaching model has the following disadvantages: [0003] 1. The teaching model only imitates the tooth contour and the shape of the pulp cavity, but does not simulate the hardness of different levels of teeth, which is quite different from the feel of clinically using high-speed drilling rigs to prepare teeth; [0004] 2. There is no reference plane or window designed to facilitate the identification of operational errors, which is not conducive to the accurate assessment of students' m...

Problems solved by technology

[0003] 1. The teaching model only imitates the tooth contour and the shape of the pulp cavity, but does not simulate the hardness of different levels of teeth, which is quite different from the feel of clinically using high-speed drilling rigs to prepare teeth;

[0004] 2. There is no reference plane or window designed to facilitate the identification of operational errors, which is not conducive to accurate assessment of students' mastery of stable control of horizontal and vertical fine operations using high-speed drilling rigs
