Ceramic veneers are permanent prosthetic restorations covering vestibular surfaces of teeth in the anterior and anterolateral segment of the dental arch. Thanks to the development of new ceramic materials and new technologies of laboratory workmanship, they can be ultra-thin, with a thickness of 0.2 to 0.5 mm depending on the materials used, and then they do not require tooth preparation (“no-prep”) or minimum preparation (up to 5%) within the enamel. They are a good alternative to conventional veneers, direct composite reconstruction or prosthetic crowns. The article presents indications, contraindications, pros and cons of “no-prep” and minimally invasive veneers. Alternative treatments have been described. Types of disorders regarding the size and shape of teeth, reasons for occurrence and incidence are described, with particular reference to conically shaped teeth. The article presents the clinical case of using “no-prep” veneers to improve the aesthetics of coneshaped maxillary lateral incisors with particular focus on detailed anamnesis, physical and radiological examination as well as photographic documentation to plan the treatment. After designing the veneers in the DSD system and on gypsum models with diagnostic waxing (wax-up), oral simulation using composite materials (mockup) was performed. After accepting the shape and proportion of the teeth, impressions were taken, the occlusion was recorded, and veneers were made. The cementation procedure was described. The patient whose case was presented was satisfied with the results of the treatment.
