| Abstract: | AIM: To construct a three dimensional(3D) finite element(FE) model of the post crown with subgingival post for restoration of the maxillary central incisor defected under gingival margin and crest,and to evaluate the feasibility og this newly designed post.METHODS: CT images of an isolated maxillary central incisor obtained through Micro-computed tomography(Micro-CT) were used to produce a 3D solid model of an incisor by CAD software of UG coupled with Mimics10.0 and Geomagic studio10.0.Four models of maxil... |
