[Esthetic evaluation of Cerec 3D anterior crowns].
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.


CONCLUSIONS
Cerec 3D anterior crowns may achieve favorable short-term esthetic effects.
