Lack of consensus in identification of interproximal contact loss risk factors

Investigators addressed risk factors for interproximal contact loss between implant crowns and natural teeth. There is currently no consensus on the causes of the condition.

In a literature review published in the Journal of Prosthodontics, the investigators used PubMed to identify eight systematic reviews and 14 case series.

The investigators found that the interproximal contact loss had a prevalence of between 16% to 66% and was more common on the mesial side of implants as well as teeth abutting a splinted implant restoration. The lack of standardized measurement strategies may contribute to the wide range of interproximal contact loss results. The investigators concluded that inadequate data may make it challenging to identify risk factors for the condition.

Establishing a definition for interproximal contact loss may be critical to come to a consensus on potential risk factors.
