Establishment of finite element models of labially or palatally tilted upper central incisors restored with fiber postcore and all-ceramic crown

Objective: To establish the three-dimensional finite element models of labially or palatally tilted upper central incisors restored with fiber post-core and all-ceramic crown. Methods: The maxillary central incisor, preparation and fiber post were scanned by Micro-CT and the three-dimensional finite element models were established by means of Mimics,Geomagic Studio, SolidWorks and Abaqus. Results: Seven 3D finite element models of labially or palatally tilted(0°, ±10°,±20°, ±30°) upper central incisors restored with fiber post-core and all-ceramic crown were obtained. Conclusions: This study successfully established the 3D finite element models of upper central incisors with different tilting angle restored with fiber post-core and all-ceramic crown.
