The influence of implant location and position characteristics on peri-implant pathology..

Peri-implant pathology is a multifactorial disease, incorporating biological and biomechanical components in its pathogenesis; however; few studies address the possible risk factors. This study investigated the effect of implant location and position characteristics on the occurrence of Peri-implant pathology. A total of 1350 patients with dental implants were included 270 patients with peri-implant pathology and 1080 healthy controls. Results demonstrated that in the absence of bacterial plaque and smoking, the variable proximity of the implant to other implants or teeth revealed a significant difference between groups with a protective effect, but not in the presence of bacterial plaque and smoking.
