Teeth Reconstruction By Reverse Engineering and Bracket Design
Abstract
Reverse engineering technology makes the product model reconstruction and expression more precise, which establishes a unified object for the product further analysis, optimization and manufacture, and had significance in the field of fast development and numerical control processing of product with complex profiles. Using reverse engineering on the tooth design can make teeth modeling more precise and perfect, and shorten the production cycle. This thesis first describes the concepts and methods of reverse engineering, then studies the modeling method of reverse engineering of teeth, and introduces the step of reverse modeling of a row of teeth in detail. Meanwhile, after the completion of reverse modeling design with the teeth point-clouds data, we also select a tooth surface, by its feature, to produce a personalized orthodontic bracket in the UG software. Through the research of the reverse modeling of the teeth and the production of personalized bracket, we developed a production process by reverse engineering technology from a resin-model to the CAD model of the teeth, and then to the CAD model of personalized bracket. The accuracy of both the final modeling of the teeth surface and the personalized bracket meets actual needs.
