Influence of Implant Fixture Design on Implant Primary Stability
Gap-Yong Oh; Sung-Hwa Park; and Seok-Gyu Kim
This research explored the effect of implant macrodesign on primary stability through resonance frequency analysis in the bovine rib bones. 50 implants from two systems were evaluated in 5-cm bovine rib bone pieces of similar quality. For group one, bone specimens with a cortical part measuring 1-mm mean thickness were selected for implant placement. For group two, cortical parts were removed and implants placed in cancellous bone. Afterwards, the implant stability quotient (ISQ) was measured and analyzed. The authors concluded that, within the limits of this study, bone quality and implant design influence primary stability.
