摘要/Abstract

摘要： 目的： 研究种植体植入深度对种植体颈部边缘骨水平的影响并探讨其临床意义。方法： 纳入57名后牙区种植患者共146枚Bicon种植体,分别测量每枚种植体植入时、修复完成时及修复负重至少5年后的曲面断层片,根据种植体植入骨下深度分四组：< 1mm组、1-2mm组、2-3mm组及> 3mm组,分析种植体颈部边缘骨水平的变化情况。结果： 经过5年以上功能性负重后,四组之间的边缘骨吸收量无统计学差异(P> 0.05);而边缘骨水平与种植体颈部平台的关系有统计学差异(P< 0.001)。结论： Bicon种植体植入不同骨下深度对种植体边缘骨吸收量无显著影响,但植入较深时种植体边缘骨稳定于种植体颈部平台之上的概率更高,从而降低种植体暴露的风险。

Abstract: Objective： To evaluate the influence of implants with different implanting depth on the marginal bone level and discuss its clinical significant. Methods： 57 patients with 146 Bicon implants in the poste- rior region were included. According to implanting depth, there were 4 groups including group A of 1 mm less below the bone level, group B of between 1mm to 2 mm below the bone level, group C of between 2 mm to 3 mm below the bone level, group D of more than 3 mm below the bone level. The marginal bone level were evaluated by means of X-ray and SPSS 17.0 software package was used for statistical analysis. Results： After 5-years functional load, there was no significant difference in crestal bone loss among four groups(P>0.05), while there was a statistical difference among four groups(P<0.05) in the relationship be- tween the marginal bone level and implant neck platform. Conclusion： There was no significant effect of Bicon implant with different implanting depth on the marginal bone resorption,but implants implanted be- low the bone level might have more chance to keep the marginal bone stabilized at or above the implant platform.
