How successful are implants placed in sites of previously failed implants? A systematic review


bigstock-Dental-implant-21445361This summary is based on the article published in Implant Dentistry: Implants Placed in Sites of Previously Failed Implants: A Systematic Review (June 2014)

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.

Key Finding

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.

    Is the ‘Key Finding’ reversed?
    Second attempts at implant placement may be slightly lower than the first attempt, but are not overall ‘low’.
    Repeated attempted without addressing the suspected reasons for the initial failure will not improve the result with following implant placement.
