摘　　要：目的:比较非埋入式种植体术后第1个月与术后第2、3两个月边缘骨吸收及1个月时骨吸收与软组织早期贴合的关系。方法:非埋入式ITI系统种植体植入33名患者口内。种植术后及1个月、3个月拍摄曲面断层片。测量术后第1个月及第2、3两个月种植体边缘骨的变化量。10 d时观察种植体周软组织贴合情况。结果:术后第1个月与第2、3两个月的骨吸收具有显著性差异(P<0.01);第1个月时骨的吸收量与10 d时种植体周软组织贴合不良呈正相关(r=0.794,P<0.01)。结论:种植体植入后第1个月边缘骨吸收量最多,且种植体周软组织贴合情况对1个月时种植体周边缘骨的吸收量有影响,生物学封闭是影响骨吸收的关键因素。Objective：To compare the amount of early marginal bone resorption in the first three months after non-sub- merged implants and to explore the relationship between the amount of early marginal bone resorption and the soft tissue healing in the first month. Method： ITI with non-submerged implants were implanted in 33 patients. Digital panoramic radi- ographs were taken during the operation, one month and three months later. The amount of marginal bone resorption was measured in the first, second and the third month after implant operation. The soft tissue healing was observed after 10 days. Results： There was significant difference （P 〈 0. 01 ）in the amount of early marginal bone resorption between one month and three months later. The early marginal bone resorption in the first month after implantation kept correlation with the soft tissue healing on l Oth day （r = 0. 794, P 〈 0. 01 ）. Conclusion：The amount of early marginal bone resorption in the first month exceeds that in the second and the third months after implant operation, and the soft tissue healing affects the amount of early marginal bone resorption in the first month. Biological seal is the critical factor influencing the early margin- al bone resorption.
