Decoding the Finite Element Method at the Prosthodontic–Periodontal Interface—Elucidating the Biomechanical Behavior of the Periodontium: A Case Review

The application of finite element method (FEM) is tried to improve our understanding of the distribution of forces in the stomatognathic system. The object to be studied is simulated in computer software to simplify the complex analysis and this approach involves pre-processing, discretization, defining the boundary conditions, loading configuration, and the output is graphically produced from the final data extractions. Aim and objective: This study was undertaken to evaluate the physical form changes of the maxillary central incisor, i.e., the stresses induced within the tooth, periodontal ligament, and alveolar bone due to the normal occlusal force. Case description: Finite element program NISA II DISPLAY III was used for accurate modeling of the tooth-periodontium system, threedimensionally. Abnormal stress levels may allow the clinician to estimate the tissue damage and implement therapeutic modalities at an appropriate stage.
