Biomechanical behavior of periodontally compromised dento-alveolar complex before and after regenerative therapy - a proof of concept

Introduction/Objective. Finite element analysis (FEA) is mathematical method which can be used for the assessment of biomechanical behavior dento-alveolar complex. The objectives were to analyze changes teeth and supporting tissues under occlusal load in cases horizontal vertical alveolar bone loss, assess potential impact tooth displacement altered stress distribution on further damage, evaluate regenerative periodontal therapy. Methods. Three patient-specific three-dimensional finite (3D FE) models developed from acquired cone beam computed tomography, comprising patient?s upper left canine, first second premolar, adjacent bone. Model 1 represented loss. 2 included intrabony defect along distal aspect #24. 3 situation six months after surgery. Displacement, Von Mises, principal stresses evaluated through FEA, moderate load. Results. FEA demonstrated that model with loss significant was present, even though clinically evident mobility absent. Biomechanical surrounding much more case comparison Six following therapy, values all parameters noticeable reduced. Conclusion. Regenerative therapy improved characteristics affected related structures.
