Objective: To compare in vitro the marginal adaptation and microleakage from 60 ceromer overlay indirect restoration using shoulder and bevel finish line. Materials and methods: There were two groups in this investigation: Group A, 30 ceromer restorations with shoulder finish line; and Group B, 30 ceromer restoration with bevel finish line. Both groups were prepared by a Bio Art milling machine using tungsteno burns. Only group B had a diferent preparation with bevel finish line. After the impressions were done, they were used for making the definitive restoration. They were cemented with an adhesive resin cement 3M ESPE Relyx™ U200 and selective etching sistem. The marginal adaptation was assessed with Greenough Leica S8APO estereomicroscope. Marginal microleakage was assessed with methylene blue and the same instrument. Means and standard deviations of the main variables were obtained according to groups and analyzed by T. Student. Results: The marginal adaptation (μm) in group A was 99.64 μm ± 14.64, and 73.57 μm ± 15.95 for group B. The marginal microleakage (μm) in group A was 172.28 μm ± 7.47 and 93.95 μm ± 10.86 for group B. The T-Student test founded statistics difference between group A and group B in the marginal adaptation and the microleakage results (p <0.0001). Conclusions: The bevel finish line presents greater marginal adaptation and less marginal microleakage compared to the shoulder finish line.
