Abstract
Objective To study CEREC Bluecam digital impressions in tooth preparation of fixed bridge. Methods Totally 80 patients of tooth preparation of 3 units fixed bridge were divided into experiment group (with CEREC Bluecam digital impressions system) and control group (with traditional method) randomly, and then captured the CEREC Bluecam digital impressions and made the dental models after the tooth preparation. Shoulders width, smooth and continuation of shoulders, paleness of shoulders edge, axial chamfers, axial converge degree, occlusal space and common path of insertion were analyzed. Results In the digital impressions in the equality of shoulders width, smooth and continuation of shoulders, paleness of shoulders edge, axial chamfers, axial converge degree, occlusal space and common path of insertion, the experiment group was better than control group: 95.0% (38 cases) vs. 62.5% (25 cases), 92.5% (37 cases) vs. 77.5% (31 cases ), 97.5% (39 cases) vs. 75.0% (30 cases), 95.0% (38 cases) vs. 72.5% (29 cases), 90.0% (36 cases) vs. 65.0% (26 cases), 100.0% (40 cases) vs. 52.5% (21 cases), and 97.5% (39 cases)vs. 75.0% (30 cases), respectively, all (P<0.05). In the dental models, the experiment group was better than control group: 87.5% (35 cases) vs. 60.0% (24 cases), 97.5% (39 cases) vs. 75.0% (30 cases), 90.0% (36 cases) vs 62.5% (25 cases), 95.0% (38 cases) vs 75.0%(30 cases), 92.5% (37 cases) vs 70.0% (28 cases), 100.0% (40 cases) vs. 72.5% (29 cases), and 100.0% (40 cases) vs. 65.0% (26 cases), respectively, (all P<0.05). Conclusions The tooth preparation quality with the CEREC Bluecam digital impressions is better than that of the traditional method. Key words: CEREC Bluecam; Digital impressions; Tooth preparation
