preparation example Construction

[0043] The preparation method of the double-layer resin tooth provided by the invention can adopt CAD / CAM method or injection molding method.

[0044] The CAD / CAM method provided by the invention comprises the steps:

[0045] Use the existing model to prepare the standard form of the inner layer structure, and then collect the model data through the scanner, the data is designed and adjusted through the design software, the output file is sent to the processing equipment, and inserted into the selected material suitable for the inner layer structure material , the inner layer structure of the standard form can be produced in batches;

[0046] On the basis of the collected model data of the inner structure, the standard external shape is designed through the design software, that is, the shape of the enamel part, and the file is output to the processing equipment, and the material suitable for the outer structure material is selected for processing, which can be mass-produced ...

Embodiment 1

[0056] Such as figure 1 As shown, the double-layer resin tooth used for oral tooth preparation training includes an inner structure 1 and an outer structure 2, wherein the inner structure is a standard preparation shape, the outer structure is a standard crown shape, and the outer structure The color of the structure is white, the color of the inner structure is yellow, and the hardness of the material of the outer structure is smaller than that of the material of the inner structure;

[0057] The material of the outer structure is polymethyl methacrylate; the material of the inner structure is inorganic powder added to polymethyl methacrylate; the thickness of the outer structure is 2mm.

[0058] The preparation method of described double-layer resin tooth adopts CAD / CAM method, comprises the steps:

[0059] Use the existing model to prepare the standard form of the inner layer structure, and then collect the model data by scanning the scanner. The data is designed and adjus...

Embodiment 2

[0063] The difference from Example 1 is that the outer structure of the double-layer resin tooth is transparent, and the inner structure is yellow.

Abstract

The invention provides a dual-layer resin tooth for oral tooth body preparation training, belongs to the field of oral medicine, and relates to dual-layer resin teeth. By means of the dual-layer resintooth, the technical problems that the preparation quantity is insufficient or excessively large, the polymerization degree is too large, and the edge is not smooth or continuous when a student has difficulty in accurately and efficiently controlling the tooth body preparation quantity and the shapes of preparation bodies in the actual operation process can be solved; by selecting materials for the inner-layer structure and the outer-layer structure of the dual-layer resin tooth with different colors and hardness, the tooth body has an obvious touch distinction in the grinding process, the hardness of the dentin of the tooth and the hardness of the enamel are better distinguished, thus an automatic prompting function is provided for a learner, the experience of the learner is improved, the learner can quickly grasp a preparation method for a certain restoration body, and quick grasping of the preparation quantity and the preparation shapes is involved.

Description

technical field [0001] The invention belongs to the field of stomatology, and relates to a resin tooth, in particular to a double-layer resin tooth used for oral cavity tooth preparation training. Background technique [0002] Prosthodontics is a clinical oral medicine course that includes multidisciplinary knowledge, and it needs to closely integrate theory and practice. Tooth preparation is a very important and main content in the early teaching of fixed restorations, and it is also the most commonly used basic clinical practice in restorative clinics. However, in the pre-practice teaching and clinical teaching, it is often found that students have various problems in the process of tooth preparation. They have a good grasp of theoretical study and standards, but they cannot be well reflected in actual operation. Problems usually occur In the preparation amount and the shape control of the preparation body, for example: the preparation amount is insufficient or too large, ...
