Improvements in the mechanical and optical properties of ceramic materials and the development of dentin adhesives have resulted in more successful results in anterior teeth restorations. Among them, porcelain laminate veneer (PLV) can achieve aesthetic improvement in a conservative way while minimizing tooth reduction. A female patient in her 20s visited for aesthetic improvement of the maxillary anterior teeth. The patient's chief complaint was aesthetic improvement of tooth discoloration after trauma and endodontic treatment, and a PLV restoration was decided to reflect the patient’s demand for minimal tooth reduction. IPS e.max Press, a lithium disilicate-based ceramic with high light transmittance and high strength, was chosen for porcelain laminate veneer. Inner surface of the veneer was treated with liner in order to block discoloration of the abutment teeth while maintaining translucency in the incisal edge. The patient was satisfied with the aesthetic result.
