%X Oral implantology (implant dentistry) is the science and discipline concerned with the diagnosis, design, insertion,restoration, and/or management of alloplastic or autogenous oral structure to restore the loss of contour, comfort,function, esthetic, speech, and/or health of the partially or completely edentulous patient. Osseointegration, aterm coined by Branemark and co-workers in early 1960s, represents a direct connection between bone andimplant without interposed soft tissue layers. The aim of the present review is to discuss various factorsresponsible for loss of oral implants. The factors contributing to failure of osseointegration have been identified asmedical status of the patient, smoking, bone quality, bone grafting, irradiation, bacterial contamination, lack ofpreoperative antibiotics, degree of surgical trauma, and operator experience. Furthermore, it appears that implantsurface properties, roughness and premature loading influence the failure pattern.
