Abstract/OtherAbstract:
Abstract This study is a phase of biomechanical study; a part of research program concerned with the new concept of in situ tooth replication. The purpose of the study was to evaluate tooth replica under each of two possible circumstances: 1) attachment via periodontal ligament and 2) osseointegration. Replicas were made of Cortoss; a bioactive glass, bone substitute. Three-dimensional finite element analysis was used to assess the stresses and strains resulting from each of two types of loads; off-vertical pressure and vertical point-force acting on natural mandibular second premolar and corresponding replicas. Natural tooth tolerated 19 MPa pressure or 85 N vertical force, periodontally attached replica tolerated 15 MPa pressure or 80 N force while osseointegrated replica tolerated 23 MPa pressure or 217 N force.
