False tooth manufacturing method

Abstract

The invention provides a false tooth manufacturing method. The false tooth manufacturing method comprises the following steps: taking a CT scanning image; importing data about the situation of the internal part of an entire oral cavity into mimics software; determining edges of body bone tissues and gingiva tissues through a thresholds tool, determining accuracy and integrity of an entire 3D model through a mask tool; checking the validity of the model through a validity tool, and judging whether the model is suitable for 3D printing or not; selecting an STL format as an output file format through the mimics software; performing personalized design through false tooth design software 3Shape Dental System or performing grinding and manufacturing by using a finished product base station; performing false tooth manufacturing on the manufactured base station. Since the false tooth manufacturing method provided by the invention applies the CT image and the 3D printing technique to an oral implanting system, the time can be greatly saved, the process flow is simple and the cost can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a method for making dentures. Background technique [0002] With the rapid development of science and technology in today's society, the application of high-tech power in the medical industry is also increasing. Dentures are currently the most effective method of tooth restoration. They can be as good as natural teeth. Because of their good effects and advantages, dentures have been well received by patients and have solved the worries of countless patients with tooth defects. [0003] However, due to the complicated process of making dentures, surgery is required to implant implants into the jawbone, which requires a high degree of precision, so the success rate is not high. Now the probability of one-time successful implantation with traditional techniques is only about 60%, and sometimes even requires It took several tries to get it in place. From the time the doctor pla...

AI Technical Summary

Problems solved by technology

[0006] (1) The technological process is too complicated and the accuracy is not high;

[0007] (2) The production cycle is too long, and the silicone rubber model and plaster model are susceptible to errors and deformations caused by external factors such as temperature and humidity;

[0008] (3) During the production of the model, the replacement and abutment have to be disassembled many times, and the screws need to be screwed many times, which is extremely prone to deviation, resulting in difficulty in positioning in the oral cavity due to angle and height issues;

[0009] (4) All production and transfer in the traditional process are rigid, which will cause loss of the model and cause a situation that does not match the real oral cavity
