口内数字化印模制作全瓷冠的临床效果观察
A retrospective study on the clinical outcomes of all-ceramic crowns restoration fabricated by oral digital im-pression
摘要
Abstract
Objective To evaluate the clinical outcomes of all-ceramic crowns whose oral digital impressions were scanned by 3Shape Trios. Methods All the impressions were scanned by Trios and all the crowns were fabricated ac-cording to the standard procedure. The restoration quality were evaluated using modified United States Public Health Service (USPHS) criteria one year after treatment. Restoration integrity、marginal adaptation、enamel wear、color satis-faction and gingival index (GI) of the prostheses were evaluated according to the modified USPHS criteria. Results The clinical 1 year survival rate of 92 porcelain crowns fabricated by 3-shape Trios digital impression and made by CAD/CAM was 100％. The scored A rates of restoration integrity、marginal adaptation、enamel wear、secondary caries、color satisfaction and gingival index of the prostheses were 100％、91.3％、98％、95.6％、96.7％and 94.7％after 1 year, respectively. Conclusion The clinical outcomes of all-ceramic crowns whose oral digital impressions were scanned by 3Shape Trios and whose crowns were made by CAD-CAM are satisfying.关键词
