Biomechanical Effects of a Maxillary Implant in the Augmented Sinus: A Three-Dimensional Finite Element Analysis
Huang HL et al. - Bicortical fixation of implants and the presence of grafted bone with greater stiffness reduced the stresses in native bone. Increasing the length of the implant in grafted bone did not reduce the stress in native bone, but it did reduce the stress in grafted bone. The effects of implant diameters on reducing bone stress are primarily a result of the increased contact area between implant and bone. The results of the FE analysis imply that the success of a sinus-augmented dental implant is heavily dependent on the implant design and rigidity of the bone grafts. [more...]
