Abstract
All-ceramic systems represent an excellent restorative alternative for fixed dental prostheses, single crowns, and veneers in the anterior dentition. With respect to improved mechanical properties, lithium disilicate ceramic material provide a broad range of indications, and extended veneers can serve as an alternative to full crowns. Although ceramic veneers represent a more conservative approach compared to crowns, the correct indication is essential to achieving the ideal outcome. The following case reports describe two types of fixed restorations of the anterior dentition: extended lithium disilicate ceramic veneers and lithium disilicate full crowns. Factors influencing treatment selection for each type of restorations are presented.
Highlights
All-ceramic systems represent an excellent restorative alternative for fixed dental prostheses, single crowns, and veneers in the anterior dentition.[1,2]Full-coverage crowns offer predictable treatment options, but a certain amount of tooth material must be removed to allow space for the required thickness of the restorative material
Silica-based all-ceramics have been proven effective in numerous long-term clinical studies as an appropriate material for esthetic restorations.[6,7,8]
The light-cured composite cement in neutral shade (Variolink Esthetic LC neutral, Ivoclar Vivadent) was applied onto prepared internal surface of each ceramic veneer that were gently seated with finger pressure
Summary
All-ceramic systems represent an excellent restorative alternative for fixed dental prostheses, single crowns, and veneers in the anterior dentition.[1,2]. Radiographic examination revealed extended composite restorations; no carious lesions and endodontically treated tooth number 13 with no findings of periapical pathology. Based on examination (age, enamel thickness, no dentin exposure, no attrition of the palatal surfaces, and possibility to place the preparation margins on enamel) extended ceramic veneers were planned to restore the teeth number 13, 12, 11, 21, and 22. The first phase of the veneer preparation involved the use of round-end diamond bur with 1.0 mm diameter (Edenta AG) to create three facial reduction grooves. The light-cured composite cement in neutral shade (Variolink Esthetic LC neutral, Ivoclar Vivadent) was applied onto prepared internal surface of each ceramic veneer that were gently seated with finger pressure. The crown preparation involved the use of a round-end diamond bur (Edenta AG) to create three facial reduction grooves respecting the axial inclinations of the tooth. The follow-up was performed 1 month after cementation and annually ( Figs. 11, 12 and 13)
