摘要: The objective of this study was to compare the load transfer mechanism and behavior two total temporomandibular joint (TMJ) prostheses: Biomet Christensen TMJ models were simulated. Computed tomography (CT) images from a specific patient used generate for use in simulation implantation prostheses. Three finite element created all. One considered intact received implant. In we five most important muscles acting on mandible incisor teeth support. model reduced strain opposite condyle by around 50% while increasing implanted condyle. changes posterior side present an increase times minimum principal strain, suggesting some bone fatigue. With implant, reduction 100%, possibility loss proximally near resection plane. Based our results, conclude that both implants influence improving symmetry distribution. implant modifies slightly presents improvements over distribution tensions disc similar non-implanted situation.
