This study evaluated whether finishing of crown preparations influences the marginal and internal adaptation of lithium disilicate-based
ceramic crowns fabricated with the Cerec system.
Conclusion: There is a significant variance in the dimension of metal and metal
ceramic crowns fabricated in the laboratories than the dimensions recommended in literature.

After the anamnesis, as well as the X-rays, photographs and upper and lower arches' evaluation (Figure 2), the case was prepared and an aesthetic rehabilitation treatment was proposed, consisting of a
ceramic crown, with zirconia infrastructure in element 15 and laminated veneers, with feldspathic ceramics in elements 11, 12, 13, 14, 21, 22, 23, 24, and 25.
