摘要： 目的:比较种植手术时即刻置入永久基台和愈合基台修复程序对种植体周围软硬组织的影响。方法:40个病人被随机分为实验组和对照组,共60颗种植体,均为平台转换种植体。实验组采用一次性永久基台修复程序,对照组采用传统愈合基台修复程序。种植手术12周后完成最终修复。于修复完成后6个月和12个月时随访,X线片检查种植体周围骨高度变化情况,记录菌斑指数、探诊深度、龈沟出血指数和Jemt牙龈指数。结果:在种植手术后到修复后6个月和12个月随访的时间内,实验组(-0.826±0.260) mm,(-0.933±0.243) mm的骨整合的吸收程度小于对照组(-1.101±0.316) mm,(-1.223±0.302) mm,统计学有显著性差异(P=0.009,P=0.004)。修复后的12个月的时间里,两组牙龈乳头高度均有明显增加,但两组之间并无显著差异。菌斑指数、探诊深度和龈沟出血指数两组间亦无显著差异。结论:在种植体植入到修复后6个月和12个月的时间里,与使用一次性永久基台相比,使用愈合基台修复程序会显著增加种植窝愈合过程中骨高度的降低。

Abstract: Objective: To compare the effect of placing the definitive restorative abutment at the time of implant placement versus at a later stage on the soft and hard tissue changes around dental implant. Methods: Forty patients were randomized to control group and test group. Sixty implants were involved. In test group patients were received the definitive abutment at the moment of implant placement, while the patients in control group received healing abutment. Platform-switched implants were used. Final prostheses were delivered 12 weeks after the implant surgery. After 6 and 12 months, the restorations were completed, radiographic assessment of marginal bone level changes and clinical status of periimplant soft tissues were detected. Plaque index, sulcus bleeding index, pocket depth, and Jemt score as well as the changes in papilla filling were assessed. Results: A significant greater bone reduction from surgery to 6 months post-loading and 12 months (P=0.009 and P=0.004) were observed when comparing the control group [(-1.101±0.316)mm and (-1.223±0.302)mm] with test group [(-0.826±0.260)mm and (-0.933±0.243)mm]. A significant increase in papilla height was observed from loading to 12 months in all implants. There were no significant differences in plaque index, pocket depth, and sulcus bleeding index between the two groups. Conclusion: The connection and disconnection of healing abutments are associated with significantly increased bone loss during the healing period between implant placement and 6 months post-loading, when compared to one time abutment placement.
