RESUMEN
Dental implant is a permanent metal fixture anchored into the jaw bone topped with individual replacement of a tooth, teeth or a bridge that screws or cements into the implant fixture. The successful outcome of implant procedure depends on a series of patient-related and procedure-dependent parameters. Predictors of success or failure are related to quality and quantity of the bone at the intended site, length of implant, axial loading, operator skills, patient's overall general health, age, habits and oral hygiene. Although long-term studies continue to show improving success rates for implants, failures occur unavoidably. Successful provision of dental implants to patients who have lost tooth/teeth and the surrounding bone, relies on careful gathering of clinical and radiological information, interdisciplinary communication and input, a detailed treatment planning and regular evaluation of the patients. Under proper conditions and diligent patient maintenance, implants can last for lifetime. The objective of this study is to assess and evaluate patients reporting to Islamic International Dental College and Hospital receiving implant therapy. We, very carefully conducted an evaluation of patients in order to find out our success rate. From August 2010 to December 2011, 31 patients received 68 implants. Vast majority of implants [63] were of Bio-Horizon of USA and rest [5] were Straumann implants of Switzerland. Out of these 68 implants, we had 3 failed cases. Further-more, we looked in detail the likely reasons of these failures
