Digital restorative dentistry and prosthodontics (12)--Restoration of wedge-shaped defect by CAD/CAM all ceramic inlay (case report)

Objective:The clinical effects were observed on the restoration of wedge-shaped defect teeth by using two lithium silicate inlay by (computer aided design/computer aided manufacturing,CAD/CAM). Method:The clinical case was a patient who had a wedge-shaped defect teeth reached deep below free gingival margin, which was going to restore with all ceramic inlay by CAD/CAM. The clinical effect assessment was made after 6 and 12 months respectively, according to modified USPHS standard. Result:The results in each review stage showed that there were no undesirable effects such as fall off, fracture and cleav-age occurred on inlay. The clinical indexes had up to A class. Conclusion:Better clinical effect can be achieved in treating teeth with wedge-shaped defect using two lithium silicate inlay by CAD/CAM, but the long-term follow-up result still had to be fur-ther observed.
