摘要: 目的: 比较角度螺丝通道基台和传统预成钛基台在上颌前牙美学区单牙修复中的临床疗效。方法: 收集2018年6月—2019年6月于上海交通大学医学院附属第九人民医院口腔种植科行上颌前牙美学区单颗牙种植修复的患者。将纳入研究的患者随机分为2组,试验组修复体使用角度螺丝通道基台螺丝固位(AG),对照组修复体使用常规预成钛基台粘接固位(CG)。记录随访6个月时的种植体成功率、边缘骨吸收、机械并发症、种植体周围软组织情况[包括牙周探诊深度(PD)、探针出血阳性率(BOP%)]、红色美学评分/白色美学评分(PES/WES)和患者满意度。采用SPSS 19.0软件包对数据进行统计学分析。结果: 最终36例(AG:19,CG:17)患者接受6个月随访,随访期间失访率为10%。到6个月随访期为止,所有种植体无松动、脱落,修复体无更换,2组成功率均为100%。试验组和对照组6个月时边缘骨吸收量分别为(0.21±0.18) mm和(0.38±0.40) mm,差异无统计学意义(P>0.05)。AG组BOP%显著低于CG,差异有统计学意义(P=0.04)。2组患者的机械并发症、PD、PES/ WES及患者满意度评分无统计学差异(P>0.05)。结论: 短期内,角度螺丝通道系统与传统预成钛基台固位的修复体均能获得可预期的临床疗效,但前者更有利于种植体周围软组织的健康状况。

Abstract: PURPOSE: To compare the clinical efficacy of angulated screw channel abutments and prefabricated titanium abutments on the restoration of single implant crowns in esthetics region. METHODS: The study was a prospective, single center, randomized controlled trial. Patients with the need of restoration of single tooth in esthetics region were included from June 2018 to June 2019. Forty patients were randomly assigned into two groups: screw-retained crowns with angulated screw channel abutments(angulated group, AG) and cemented crowns with prefabricated Ti abutments (cemented group, CG). Clinical and radiological evaluations were performed on the day of final crowns delivery and 6 months later. Implant survival rate, marginal bone loss (MBL), mechanical complications, peri-implant conditions (Probing depth, PD; bleeding on probing, BOP%), pink esthetics score/white esthetics score(PES/WES) and patients' satisfaction were assessed. The data was analyzed with SPSS 19.0 software package. RESULTS: Thirty-six patients (AG: 19, CG: 17) attended the 6-month clinical trial. Implant survival rates were both 100% in two groups. The MBL was (0.21±0.18) mm for AG and (0.38±0.40) mm for CG (P>0.05). The BOP% was significantly higher in AG than that in CG (P=0.04). No significant difference of mechanical complications, PD, PES/WES and patients’ satisfaction was found between the two groups(P>0.05). CONCLUSIONS: Based on the present results, both treatment options show acceptable clinical outcomes in the short term. Angulated screw-retained crowns may benefit the peri-implant soft tissue; however, studies with long-term follow-up are needed to verify the results.
