Analysis of the risk of interproximal contact loss between adjacent teeth and implant-supported fixed prostheses: A retrospective cross-sectional study

Delivery time, the contralateral side, root configuration, and an opposing plunger cusp can influence the development of mesial ICL. However, no significant relationship was found between ICL and peri-implant tissue health. Additionally, participants' awareness of food impaction was found to be associated with the occurrence of mesial ICL.
