Introduction: Lithium disilicate-based ceramics are extensively used in restorative dentistry, considering these materials combines adequate mechanical and optical properties, which, associated with dentin bonding by resin luting cement, makes them suitable for load-bearing posterior regions. This case report aims to describe the clinical and laboratory steps of a ceramic crown restoration. Case Report: A 30-year-old female patient had the second right maxillary premolar restored with lithium disilicate. The tooth was conditioned with phosphoric acid 37, followed by washing with water and drying with air jet. After this stage, the adhesive was applied to the surface and blasted with air. The prosthetic part was prepared with 10% hydrofluoric acid on the internal surface, washed with water, application of silane and adhesive. For definitive cementation, resinous cementing agent was used on the internal surface, the excess was removed and photopolymerization was performed. Conclusion: This case report represents a successful esthetic treatment and shows resistant ceramic restorations that can be placed over minimally invasive tooth preparations.
