Despite the high success rates reported for dental implants,(1, 2) failures requiring implant removal do occur. The overall first year failure rate may vary between 3% and 8%.(3) There are different patient-related reasons to avoid reimplantation, such as additional costs, fear of additional pain, and fear of a second failure4; nevertheless, implant replacement still remains a therapeutical option to be considered.
Purpose of the Review
The aim of this study was to systematically review the literature on implant placement in sites of previously failed implants and to assess survival and success rates of the replacement implants to investigate the effectiveness of the procedure.
Survival rates of implants placed in the areas of previously failed implants are low, although they should not discourage clinicians from a second or even a third attempt.
