Bonded porcelain restorations are a predictable and durable treatment option with which not only esthetic appearance but also the strength and function of teeth can be re-established. One of the most important issues of today's dentistry is the preservation of sound enamel. Following biomimetic principles, employing minimally invasive applications and adhesive technologies are of paramount importance for successful restorations. The mock-up technique is advised for delicate removal of the required space for thin porcelain veneers minimally. Besides minimally invasive preparation, long-term success is determined by the adhesive quality of the laminate veneers. This case presentation demonstrates restoration of anterior dentition where the wear of incisal edges posed a negative effect on the smile of the patient. Before bonded porcelain veneers were adhesively cemented, incisal lengthening with direct resin composite and gingival contouring was performed. By using the mock-up technique, minimal preparations were made with the outline ending in enamel only. For cementation of these restorations, step-by-step adhesive procedures are presented.
