It is considered that periodontal disease is one of risk factors of the loss of interproximal contact (IC) between fixed implant prostheses and adjacent teeth, but it is not reported yet. In this study, the relation between the state of periodontal disease and the loss of IC was investigated for 105 patients. As a result, there is a significant correlation between the loss of IC and the degree of the periodontal disease(r=0.246, P=0.001), and there is a significant correlation between the loss of IC and food impaction(r=0.344,P=0.01). Therefore, it is necessary to observe the state of IC and the periodontal tissue carefully at the time of implant maintenance, and, if the loss of IC was observed, it was suggested that it was necessary to restore the loss of IC.

牙周病被认为是固定种植义齿与邻牙失去近中接触(IC)的危险因素之一，但尚未见报道。本研究对105例牙周病患者的牙周疾病状态与IC丢失的关系进行了研究。结果表明，IC缺失与牙周病变程度呈显著正相关(r=0.246，P=0.001)，与食物嵌塞呈显著正相关(r=0.344，P=0.01)。因此，在种植体维护时，有必要仔细观察IC和牙周组织的状态，如果观察到IC的丢失，建议有必要恢复IC的丢失。
