Abstract: PURPOSE: To investigate clinical application, aesthetics, stability and bio-compatibility of zirconia all-ceramic crowns in prosthodontic patients. METHODS: Computer aided design and manufacturing techniques were used to make zirconia all ceramic crowns in 40 patients. They were divided into 2 groups according to the thickness of the gingival thickness. After 12 months of clinical observation, the aesthetics, stability, and bio-compatibility were evaluated by the crown color, crown edge fitness, losing ratio and gingival health. The data were analyzed using SPSS 13.0 software package. RESULTS: Slight marginal discrepancy was observed in 2 zirconia all ceramic crowns, no evidence of decay was observed at 1 year. CONCLUSIONS: Zirconia all ceramic crowns have a low fracture rate, good biological properties and excellent esthetic properties. It is ideal esthetic prosthesis.
