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.
种植体周围病变是一种多因素疾病，其发病机制包含生物学和生物力学成分；然而，很少有研究探讨可能的风险因素。本研究调查了种植体位置和位置特征对种植体周围病变发生的影响。共纳入1350例牙种植体患者，其中270例患有种植体周围病变，1080例为健康对照。结果表明，在没有菌斑和吸烟的情况下，种植体与其他种植体或牙齿的不同距离在两组之间显示出显著差异，具有保护作用，但在有菌斑和吸烟的情况下则不然。
