Proximal Contact Loss in Implant-Supported Restorations: A Systematic Review and Meta-Analysis


Now online in the Journal of Prosthodontics, a new systematic review and meta-analysis to evaluate the overall prevalence of proximal contact loss (PCL) in implant-supported restorations and investigate the correlations between several risk factors and the development of this condition.

Cohort studies, cross-sectional studies, and retrospective evaluations which included patients who received implant-supported fixed-partial dentures were deemed eligible for inclusion in the review.

Fifteen studies met the inclusion criteria and a total of 11,699 restorations were evaluated in the final sample. The overall prevalence was 20% at the implant-restoration level and 26.6% at the contact point level.

Although the review and analysis could not provide insight into the cause of this condition or the possible effects that the opening of a contact point has on the health of the peri-implant tissues and the adjacent teeth, the authors conclude that PCL is a frequent complication which may cause food impaction and damage to the interproximal tissues.
