Evaluaton of hexagon deformation of dental implant regarding to the insertion force

Abstract

The aim of this study is to evaluate hexagon deformation of dental implant regarding to the insertion force, verifying the external hexagon platforms before and after each torque performed. Thereunto, 25 implants were selected and divided into 5 groups with 5 implants each one; every group received different torque 10N, 20N, 30N, 40N and 100N. A Surgical torque wrench was used, with the implant installation key, what established the insertion force for each group. The platform measurements were carried out before and after apply the torque by analyses of images acquired through implant platforms. We conclude, by this study methodology, 100N forces were able to cause changes on hexagon dimensions; however, it did not damage the prosthesis platform adaptation.
