Abstract

Abstract:

Objective

To develop a method to construct three-dimensional finite element model of badly damaged maxillary first molar restored with post and cores.

Methods

Based on the data acquired by two-aspects CT scanning， a three-dimensional finite element model of badly damaged maxillary first molar restored with post and cores was constructed by using Mimics software， Ansys software and Freeform model software in combination.

Results

The shape and structure of the three-dimensional finite element model of badly damaged maxillary first molar restored with post and cores were vivid and intact.

Conclusions

More image data could be acquired by improved CT scanning mode. The precision of three-dimensional finite element model could be improved by combining Mimics and Ansys softwares. Freeform software is a simple and direct way to construct three-dimensional finite element model of complex post and cores.

Key words: Maxillary first molar, Post and core, Tooth restoration, Computer-aided design
