Construction of three-dimensional finite element models of cantilever resin-bonded bridg with three differ-ent retainer designs / 实用口腔医学杂志

ABSTRACT

Objective:To construct three-dimensional(3D)finite element models with 3 different retainer designs.Methods:The intact maxillary first premolar was scanned using Micro-CT.CT images were reconstructed through Mimics 10.0 software and the prima-ry 3D models were gained after improvement in the Geomagic 7.0 software,The abutments and prosthesis of cantilever resin-bonded bridg that could be identified by the FEA software were accomplished.Results:The 3D models of cantilever resin-bonded bridg with 3 different retainer designs were constructed successfully using the maxillary first premolar as the abutment.The mesh number were 553 959,468 134,516 748,respectively.Conclusion:Using Micro-CT and finite element analysis the 3D reconstruction of the cantile-ver resin-bonded bridges may be more accurate for biomechanical analysis.
