Objective To observe the short-term effect of clinical application of Cerec 3D anterior crowns.Methods A total of 16 patients were restored with 31 Cerec 3D anterior crowns.All restorations were stained before cementation.The evaluation started 1 week after luting.The restorations were examined in accordance with the modified US Public Health Service (USPHS) criteria at baseline and every 6 - 12 months.Results The observation period of 31 Cerec 3D anterior crowns varied from 8 to 33 months.The mean observation period was 22 months.All restorations scored A or B by modified USPHS standard.And 22 out of 31 restorations scored A for all criteria while 8 restorations scored B in color matching.Slight differences of translucency and chroma could be observed.Between baseline and follow-up examinations,insignificant shift from A-to B-rating occurred.Conclusion Cerec 3D anterior crowns may achieve favorable short-term esthetic effects.
