Objective  To study the clinical efficiency of making inlay

veneer

and crown with CEREC3D computer-aided design computer-aided manufacture (CAD/CAM) system.     Methods  Ceramic restorations including 65 inlays

46 veneers

and 21 crowns were made with CEREC3D system for 86 patients in our department. Their processing time was recoded

and the clinical effects were analyzed with modified USPHS criteria in 6 and 12 months later.    Results  The average processing time was about 15 min. No fracture

loosen

split

lose of the restoration

or secondary caries of tooth was seen

except 1 onlay and 1 crown were broken off and partial lingual teeth of 1 inlay was fractured. Restorations reached almost standard of  A grade in each item according to modified USPHS criteria. Evaluation showed that there was no statistically significance between the items in 6 and 12 months (P＞0.05).    Conclusion  CEREC3D system has notable short-term clinical outcomes in ceramic restoration with shorter processing time in clinic

and may be used as a practical approach in clinical restoration.
