Bionic Joint Surface Shape’s Influence on Coating Tool’s Bonding Strength between Coating and Substrate

Abstract:

This paper takes healthy teeth as research objects, and carries on data fitting to the enamel-dentinal joint surface based on least squares method and optimizes it. According to the result of data fitting, a series of joint surface shapes are designed and mathematical models of bionic design surfaces are given out. ABAQUS software is used to simulate and analyze the bonding strength of coating and substrate for different joint surfaces based on the transverse substrate stretched test, and the best shape parameters are obtained under a certain coating thickness. At last, the above data with the results of different plane joint surface are compared. The results show that the new bionic designed joint surface based on the enamel-dentinal joint surface of teeth can optimize coating stress distribution and improve coating tool’s bonding strength.
