Biomechanical effects of bone quality and design features in dental implants in long-term bone stability

Abstract This study analyzed the effects of implant design factors (diameter, length, and connection type) bone quality on long-term success implantation via finite element (FE) analysis, considering remodeling process. A total 36 cases three-dimensional FE model, with an complex located in mandibular section molar region, were considered. An analysis dental was implemented Abaqus UMAT subroutine. preload 32 N?cm average biting force 50 N applied during process as loading conditions. After process, a maximum 200 oblique direction. The stability peri-implant by measuring apparent density over time principal strain cancellous bone. differs depending host conditions features. initial condition greatly influenced final distribution surrounding implant. need for evaluation has increased under placing short-length narrow-diameter implants poor-quality bones.
