角度螺丝通道基台在上颌切牙种植修复的临床应用

目的:评估应用角度螺丝通道基台种植修复上颌切牙的临床效果。方法:临床选择2015年12月前使用角度螺丝通道基台行上颌切牙种植修复15例。随访6个月,观察方法为X线片、临床检查及患者满意度调查,分析其存留率、骨吸收情况、软组织及美学效果。结果:使用角度螺丝通道基台的上颌切牙种植义齿存留率为100%;种植体近远中牙槽骨吸收量为(0.447±0.121)、(0.355±0.127) mm,软组织状况良好; 93.3%患者对种植修复表示满意。结论:使用角度螺丝通道基台行上颌切牙种植修复是一种微创、简洁的种植治疗方案设计,有一定的临床推广价值。

Clinical Application of Angulated Screw Channel Abutment in Implant-supported Rehabilitation of Maxillary Incisors.

Objective: To evaluate the clinical outcome of implant-supported rehabilitation of maxillary incisors using angulated screw channel (ASC) abutment with or without simultaneous GBR. Methods: Fifteen patients with fifteen implants placed in anterior maxilla restored with ASC abutment were followed up for six months. The cumulative survival rate, bone resorption around implants, peri-implant soft tissues, and esthetics were analyzed through X-ray, clinical examination, and patient satisfaction investigation. Results: After an average follow-up of 6 months, the implant cumulative survival rate was 100%. The mesial and distal marginal bone loss of implants was 0.447±0.121mm and 0.355±0.127mm, respectively. Peri-implant soft tissues achieved satisfactory outcome and 93.3% patients were satisfied with the restoration. Conclusion: The implant-supported rehabilitation of maxillary incisors using ASC abutment is a minimally invasive and simplified therapeutic schedule with a certain clinical application value.
