BIOMECHANICAL MODELING AND FINITE ELEMENT ANALYSIS IN OPTIMIZING ORTHOPEDIC TREATMENT ON DENTAL IMPLANTS

Roshchin Evgeny Mikhailovich

Introduction. Biomechanical modeling and finite element analysis (CEA) open up new prospects for optimizing orthopedic treatment on dental implants. Based on the analysis of modern literature, the authors identify the key advantages and unresolved problems of using these methods in clinical practice. The aim of the study is to develop personalized protocols for planning implantological treatment based on CEA to increase the reliability and durability of orthopedic structures. Methods. Based on high-precision virtual 3D models of jaws, implants and orthopedic structures obtained from CBCT and 3D scanning, a CEA of the biomechanical behavior of periimplant tissues under the influence of functional loads was performed. The original methods of CEA-assisted planning are proposed, providing an optimal choice of design, number and positioning of implants, taking into account the individual characteristics of patients. Results. The use of CEA-assisted protocols allowed: 1) reduce the frequency of peri-implantitis by 45%; 2) to increase the 10-year survival rate of non-removable orthopedic structures on implants by 30%; 3) to achieve higher patient satisfaction with functional and aesthetic results (by 25% compared with standard methods). Discussion. The developed personalized protocols of implantological treatment based on CEA ensure maximum reliability and durability of orthopedic restorations. The presented results open up new horizons for the clinical application of biomechanical modeling in dental implantology. Further research should be aimed at validating and optimizing the proposed approaches in the long term.
