Abstract
The purpose of this study was to compare removal torque of osseointegrated implants in three types of vascularized bone.
Scapula, iliac crests, and fibula were used as samples from five formaline-fixed cadavers, and the removal torque of implants was measured with torque gauge meter (Tohnichi 15 BTG-N). In addition, the thickness of cortical bone and total bone were measured. As a result, the fibula had the strongest removal torque of implant, and the thickest cortical bone among the three bone flaps. There was a correlation between the removal torque and the thickness of cortical bone, though there was no significant correlation between removal torque and the thickness of total bone.
These results suggested that the fibula has the strongest initial fixed strength for osseointegrated implants.
