种植体-基台界面至冠-基台粘接界面距离对边缘骨吸收影响:4-5年回顾性研究

The effect of the distance from the implant-abutment interface to the porcelain-abutment bonded interface on marginal bone loss: a 4-5 year retrospective study

目的:分析Bicon种植体种植体-基台界面(implant-abutment interface,IAI)至修复体-基台粘接界面(porcelain-abutment bonded interface,PAI)之间的距离对边缘骨吸收(MBL)的影响。方法:选取2011年6月至2014年12月于本院种植的患者,通过影像学分析IAI至PAI的距离与MBL之间的相关性。结果:在二维水平上,IAI至PAI的垂直距与MBL、点距与MBL之间显示出显著相关性(P<0.01),相关程度为弱相关。水平距与MBL之间未显示显著相关性(P>0.05)。结论:在不影响美学的条件下,适当增加IAI与PAI的距离,有利于骨组织的保存。

Objective: To analyze the effect of the distance from Bicon implant-abutment interface(IAI) to prosthesis-abutment bonded interface(PAI) on marginal bone loss(MBL). Methods: Select the patients who meet the criteria from June 2011 to December 2014, and analyze the correlation between the distance between IAI and PAI and MBL by imaging. Results: On the two-dimensional level, the vertical distance and distance between points from IAI to PAI showed a significant correlation with MBL(P<0.01), and the degree of correlation was weak. There was no significant correlation between horizontal distance and MBL(P>0.05). Conclusion: Without affecting aesthetics, properly increasing the distance between IAI and PAI is beneficial to the preservation of bone tissue.
