Effects of non-carious cervical lesion size, occlusal loading and restoration on biomechanical behaviour of premolar teeth

摘要

BackgroundInformation on fracture biomechanics has implications in materials research and clinical practice. The aim of this study was to analyse the influence of non-carious cervical lesion (NCCL) size, restorative status and direction of occlusal loading on the biomechanical behaviour of mandibular premolars, using finite element analysis (FEA), strain gauge tests and fracture resistance tests.
