美学区应用角度螺丝通道基台的临床效果评价

摘要

目的:对美学区应用角度螺丝通道(Angulated Screw Channel,ASC)基台的临床效果进行评价.方法:收集美学区种植修复患者9例,永久修复时应用CAD/CAM设计制作的ASC基台修复体,并通过红色美学指数(Pink Esthetic Score,PES)和白色美学指数(White Esthetic Score,WES)、牙龈乳头指数(Papilla Index Score,PIS)、视觉模拟评分法(Visual Analogue Scale,VAS)等指标评价美学区ASC基台的应用效果.结果:种植体骨结合良好,义齿存留率100％,红、白色美学指数PES及WES平均分分别为9.7分及9.9分,牙龈乳头指数PIS为2.4分,VAS患者满意度调查结果显示,患者对最终美学效果满意.结论:ASC基台可将位于美学区的穿出位点转移到腭侧,实现了粘结固位至螺丝固位的转换,避免因粘结剂滞留导致的生物学并发症,有助于获得理想的美学修复效果.%Objective: To evaluatethe clinical effect of Angulated Screw Channel(ASC)abutment in aesthetic area.Methods:Nine cases were selected,which were treated by using ASC abutment designed and made by CAD/CAM in permanent restoration.The application effect of the ASC abutment in the aesthetic area were evaluated by PES,WES,PIS,VAS and other evaluating indicators.Results: The survival rate of the implants was 100％with good osseointegration.The average scores of the red and white aesthetic index indicated by PES and WES were 9.7 and 9.9 respectively,while the gingival papilla index indicated by PIS was 2.4.Furthermore,the patient satisfaction survey showed that the patients were satisfied with the final aesthetic effect.Conclusions: The application of ASC a-butment can transfer theaccess holein the aesthetic area to the lingual side,and may achieve the screw-retained fixation to replace ad-hesive-retained fixation,which can help avoiding biological complications due to retention of adhesives and finally achieve ideal aesthetic restoration.
