All-ceramic restorations have gained patient acceptance and are increasingly utilized in aesthetic appearance-related restorations. This case report describes the utilization of a leucite-reinforced porcelain to fabricate all-porcelain crowns for maxillary anterior restorations for functional and aesthetic improvement. This particular porcelain system was selected for its high tensile strength, fracture resistance, and excellent marginal adaptation. The new generation adhesive agents combined with highly filled resin luting cements allow the clinicians to create an integral unit between the restoration and the natural tooth. This bond provides high compressive strength and low microleakage. The preparation procedure, the fabrication of tooth-colored wax crowns, the wax try-in procedure, and the laboratory technique of all-porcelain crown fabrication are discussed in detail, using intraoral photographs of the case to illustrate each applicable procedure. The learning objective of this article is to share the knowledge of all-porcelain restoration principles and application and to provide a detailed description and illustration of each clinical procedure.
