Abstract
- Lithium disilicate gradation block that have been recently introduced and used in dental clinics have superior light transmittance compared to zirconia-based restorations, so that when applied to anterior restorations, better esthetic results are expected. In addition, it has the advantage that the flexural strength is sufficient and chemical bonding with resin cement is possible. However, high transparency could be a disadvantage in the restoration of abutment teeth with severe discoloration, and various methods have been tried to compensate for this. In this study, in the restoration of central incisors with severe discoloration of the abutment, the inner surface of the crown made of lithium disilicate-based polychromatic blocks was treated with a liner to block the discoloration, and thus aesthetically satisfactory results were obtained.
