Abstract: 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 9.9respectively, 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. Conclusion: The application of ASC abutment can transfer theaccess holein the aesthetic area to the lingual side , and may achieve the screw-retained fixation to replace adhesive-retained fixation,which can help avoiding biological complications due to retention of adhesives and finally achieve ideal aesthetic restoration.
