The use of endosseous titanium implants, for the replacement of missing teeth, has become a predictable treatment alternative in restorative dentistry. Success of dental implants appears to be related to the quality of bone. Bone of high quality will ensure better implant stability and, consequently, better conditions for osseointegration. This thesis reviews both and human data related to bone quality in association with endosseous titanium implant placement. / Biomechanical pull out testing is one among several methods used to quantitatively assess the forces required to remove an implant from bone. Pull out testing has the advantage of assessing the biomechanical stress between two materials of different physical and chemical properties, in this case bone and a titanium, implant surface. The variability of our results in the animal model led us to review our laboratory notes. Interesting correlations between the initial implant stability and the eventual pull out values were identified. Clinical data involving many variables were available from previous clinical trials and an attempt was made to retrospectively evaluate this information. The goal of this process was to determine, clinically, if a similar correlation could be identified between initial impressions at the time of implant placement and ultimate implant success. / Clinical data revealed that the following variables were important for the final prognosis of an implant: dental arch, implant length, method of insertion, bone graft, the surgeon, jaw bone quality and jaw bone quantity. Using a sophisticated statistical analysis, generalized estimating equation, most of these factors were found only to indirectly influence the success or failure of an implant. Our clinical findings suggested that jaw bone quality and quantity were the primary determining factors for implant success. This supports our observations from the animal study.
