Statement of problem: Use of all-ceramic prostheses fabricated with CAD/CAM systems is increasing in the dentistry. Marginal fidelity in produc-tion of all-ceramic restoration has important clinical implications and is a key consideration issue in CAD/CAM production as well.

Purpose: Theobjective of this study was to analyse marginal fidelities of Procera Allceram Crown.

Material and methods: On 56 patients treated with Procerasystem Allceram Crown at Dankook Dental Hospital, marginal discrepancies of 101 abutments were measured by stereomicroscope at coping and fi-nal restoration stages. Paired t-test and one-way analysis of variance on marginal discrepancy data were conducted to determine the presence of sig-nificant differences between measurement and measuring point stages.

Results: Marginal discrepancies of final restoration (45.82 ¡¾30.84 §­) werelower than alumina coping (53.84 ¡¾ 38.83 §­). Furthermore, the differences were found to be statistically significant at 95% confidence level.Anterior marginal discrepancies were lower than posterior marginal discrepancies, but they were not statistically significant. Lingual marginal dis-crepancies were higher than other measurement sites, and the differences were found to be statistically significant at 95% confidence level.

Conclusion: Within the conditions of this study, marginal fidelities of Procera Allceram Crown were acceptable, and after porcelain build-up, mar-ginal fitness improved over alumina coping. More careful scanning is needed for better results.
