Brief Summary

In this study, we collected and analysed the review results of 100 patients over 18 years of age who received implant fixed restorations in the Department of Stomatology of the First Hospital of Nanjing, China. The aim was to investigate the incidence of loss of contact between implant restorations and adjacent teeth and its influencing factors. Our findings may provide better insights for treatment planning and prevention of PCL.

Detailed Description

Food impaction is a common complication after implant-supported restorations. Several studies have reported that more than 40%-66.9% of patients feel food impaction between the implant restoration and adjacent natural teeth. The most common cause of food impaction after implant restoration is the proximal contact loss(PCL), which has been reported to occur in 34% to 65% of cases. The location of PCL creates discomfort and leads to gingival inflammation and even peri-implant bone resorption, which ultimately leads to loosening of the implant. In our long-term clinical observation, not all final restorations suffer from PCL. The occurrence of PCL may be related to a number of factors such as age, gender, functional time, and so on. However, the literature addressing this issue is still limited. In this study, we collected and analysed the review results of selected patients who underwent implant-supported restorations in the First Hospital of Nanjing, China, to investigate the incidence of PCL between the implant restorations and the adjacent teeth adjacent , and the factors influencing it. Our findings may provide better insights for treatment planning and prevention of PCL.
