A Systematic Review of Dental Implant Failure Rates in the Esthetic Zone

Abstract

This systematic reviewevaluated the failure rates of dental implants placed in the aesthetic zone. A thorough search was conducted across various electronic databases, including manual reference checks, using relevant keywords and inclusion criteria based on the PICO framework (population, intervention, control, and outcomes). A total of 11 studies were included in the analysis, consisting of both randomized controlled trials (RCTs) and non-randomized studies. The overall failure rate was found to be low at 2%, with a marginal bone loss of 1%. Aesthetic outcomes, such as pink aesthetic scores, were favorable, with a small percentage of mid-facial soft tissue and papillary recessions. This analysis demonstrates that dental implant failure in the aesthetic zone is minimal, with low bone loss and satisfactory aesthetic results.
