Case Report on Full-Ceramic Lithium Disilicate Crowns Using a Customized Preparation Technique with Modified Chamfer on the Vestibular Surface and Vertical-Prep on the Oral Surface Across Multiple Teeth

This case report details the clinical use of layered lithium disilicate crowns, employing a customized technique that combines a modified chamfer on the vestibular surface with Vertical-Prep on the lingual surface. This concept was applied on six mandibular anterior teeth (4. 1, 4. 2, 4. 3, 3. 1, 3. 2, 3. 3) trying to achieve mechanical advantage of the vertical preparations alongside the aesthetic accomplishment of the modified chamfer technique. The lithium disilicate material used was characterized by high strength and biologic characteristics of the material made it possible to achieve highly satisfactory esthetic result with the color near to the patient’s original teeth. In terms of function, the restorations provided good stability and comfort to the patients and none of the patients complained any discomfort in the six-year follow up period. Both the crowns were proved to have long term sturdiness with out any fractures or wearing and thus this treatment modality can be held as successful outcome. This case also supports the concept of having a well-developed mode of preparation in tandem with using high quality ceramics in the creation of durable, esthetical dental restorations.
