title: Comparison of load transfer by implant abutments of various diameters.
abstract: The effects of diameter and position of implants on displacement and stress distribution, were investigated. ITI Hollow Cylinder two-stage implants with various diameters (3.5 mm, 4.5 mm and 6 mm) and positions are compared on the basis of a two dimensional finite element analysis. The mathematical results of this study demonstrate that, using conventional assumptions for stress levels in the crestal bone, relatively large diameter implants are preferable in the posterior mandibular area.
