A Micro-Computed Tomography Analysis of Internal and Marginal Fit of Fixed Partial Dentures: Effect of Preparation Finish Line Designs on Monolithic Zirconia and Heat-Pressed Zirconia Reinforced Lithium Disilicate.

The internal and marginal fit of the ceramic fixed partial dentures can be affected by the finish line design and ceramic type. The feather-edge finish line had a negative impact on the marginal and internal fit of ceramic fixed partial dentures at certain measurement points. Regarding the effect of finish line design on abutment teeth, the difference in fit was only detected at the finish line area of the anterior abutment (canine) with the feather-edge finish line This article is protected by copyright.
