角度螺丝通道基台一体冠在美学区种植修复中的短期临床效果研究

Clinical application of integrated angulated screw channel abutment crown in implant-supported rehabilitation of aesthetic area

目的探讨美学区应用角度螺丝通道(ASC)基台一体冠进行种植修复的临床效果。方法采用ASC基台一体冠对16例患者行美学区种植修复,术后随访1年,对种植体存留率、美学效果、种植体边缘骨吸收、患者满意度进行评估。结果ASC基台一体冠修复美学区牙齿缺失种植体存留率为100%;红色美学分值和白色美学分值平均分分别为9.5分和9.4分;种植体近远中边缘骨吸收量分别为(0.439±0.123)mm和(0.341±0.118)mm;VAS满意度平均得分为8.9分,所有患者对种植修复效果均满意。结论使用ASC基台一体冠行美学区种植修复是一种较理想的设计方案,具有一定的临床应用价值。

Objective To evaluate the clinical effect of integrated angulated screw channel(ASC)abutment crown in implant-supported rehabilitation of the aesthetic area.Methods Sixteen patients who received single implant-supported rehabilitation using integrated ASC abutment crown in the aesthetic area were included in the study.After one-year follow-up,the cumulative survival rate,aesthetic effectiveness,bone resorption around implants,and patient satisfaction were analyzed through periapical film,clinical examination,and the visual analog scale(VAS).Results The implant cumulative survival rate of the integrated ASC abutment crown in the implant-supported rehabilitation of the aesthetic area was 100%.The average pink esthetic index scores reached 9.5,and the white esthetic index scores reached 9.4.The mean marginal bone loss of implants was(0.439±0.123)mm at the mesial side and(0.341±0.118)mm at the distal side.The average VAS satisfaction score was 8.9,which showed that all patients were satisfied with the final restorative effect.Con⁃clusion Using integrated ASC abutment crown for implant restoration is an ideal implant restoration design in the aesthetic zone and can be applied clinically.
