英文摘要:

Background: This paper introduces a method to digitally design a virtual model of a tooth preparation of the mandibular first molar, by using the commercial three-dimensional (3D) computer-aided design software packages Geomagic and lmageware, and using the model as an input to automatic tooth preparing system.

Methods: The procedure included acquisition of 3D data from dentate casts and digital modeling of the shape of the tooth preparation components, such as the margin, occlusal surface, and axial surface. The completed model data were stored as stereolithography (STL) files, which were used in a tooth preparation system to help to plan the trajectory. Meanwhile, the required mathematical models in the design process were introduced.

Results: The method was used to make an individualized tooth preparation of the mandibular first molar. The entire process took 15 min.

Discussion: Using the method presented, a straightforward 3D shape of a full crown can be obtained to meet clinical needs prior to tooth preparation. (C) 2013 Elsevier Ltd. All rights reserved.
