OBJECTIVES
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.
CONCLUSIONS
Using integrated ASC abutment crown for implant restoration is an ideal implant restoration design in the aesthetic zone and can be applied clinically.
目的
评估一体化成角螺丝通道（ASC）基台冠在美学区种植修复中的临床效果。
方法
本研究纳入16例在美学区采用一体化ASC基台冠进行单颗种植修复的患者。经过1年的随访，通过根尖片、临床检查及视觉模拟量表（VAS）分析种植体的累计存留率、美学效果、种植体周围骨吸收情况及患者满意度。
结果
一体化ASC基台冠在美学区种植修复中的种植体累计存留率为100%。粉色美学指数平均得分达9.5分，白色美学指数平均得分达9.4分。种植体近中侧平均边缘骨吸收量为（0.439±0.123）mm，远中侧为（0.341±0.118）mm。VAS满意度平均得分为8.9分，表明所有患者对最终修复效果均满意。
结论
采用一体化ASC基台冠进行种植修复是美学区理想的种植修复设计，可应用于临床。
