摘要: 目的: 比较种植联冠修复中组合使用螺丝与粘接固位修复方式(SCP)与单纯粘接及螺丝固位方式在修复体固位并发症方面的差异。方法: 收集后牙区多单位种植修复体戴牙后2年的患者152例,共331颗种植体。其中使用螺丝固位的44例(S组,94颗植体);口内粘结固位56例(C组,121颗植体);螺丝固位与粘接固位联合运用52例(SCP组,116 颗种植体,其中螺丝固位52颗,粘接固位64颗)。比较3组病例负重2年后粘接及其螺丝机械并发症的发生情况。 结果: (1)固位螺丝松动的发生率,SCP组和C组无差异(P>0.05),两组均低于S组(P<0.05);(2)SCP修复方式的口内粘接单元粘接失败发生率与口外粘接的螺丝固位组无差异(P>0.05)。结论: 在多单位后牙修复中 SCP固位方式可以在实现被动就位的前提下降低螺丝松动和粘接失败的风险,适用于后牙修复空间不足或是穿龈袖口较深的病例。

Abstract: Objective: To compare the differences among SCP (screw and cement-retained implant-supported dental prosthesis) group, adhesion retention group, and screw retention group for multi-unit implant crown restoration. Methods: A total of 152 patients (331 implants) were collected, in which 44 cases (94 implants) were fixed with screws, 56 cases (121 implants) were treated with intraoral adhesion, and 52 cases (116 implants, 52 implants were retained with screws and 64 implants with adhesive retentions) were treated with SCP. The incidences of adhesion and screw mechanical complications in 3 groups were compared after 2-year use. Results: There was no significant difference in the incidence of screw loosening between the SCP group and the cement-retained group, but these incidences of both groups were lower than that in the screw-retented group. There was no significant difference in the failure rate between the intraoral bonding units of SCP group and the extraoral bonding units of screw-retented group (P>0.05). Conclusion: The multi-unit SCP retention method can reduce the risk of screw loosening and bonding failure while having passive fit, and is suitable for the cases with insufficient occlusal space for crown restoration and/or with deep soft tissue cuff.
