“…Replicating natural teeth is challenging for clinicians working in the aesthetic area. Achieving optical, biological, and anatomical outcomes that mimic the natural dentition and satisfy patient demands is hindered by current restorative materials and color-matching techniques [32][33][34]. Color matching is a complex process that begins with selecting the appropriate tooth shade, which can be achieved through either visual assessment or with digital devices [35,36].…”

Ultra-Translucent Zirconia Laminate Veneers: The Influence of Restoration Thickness and Stump Tooth-Shade

This in vitro study aimed to evaluate the final shade of translucent zirconia laminate veneers with varying thicknesses over teeth with different shades. Seventy-five chairside computer-aided design/computer-aided manufacturing (CAD/CAM) shade A1 third-generation zirconia dental veneers, with thicknesses of 0.50 mm, 0.75 mm, and 1.00 mm, were placed on resin composite teeth with shades ranging from A1 to A4. The laminate veneers were divided into groups based on thickness and background shade. All restorations were evaluated with a color imaging spectrophotometer, to map the veneer surface from A1 to D4. Regardless of the thickness or background shade, all dental veneers showed color alteration from the original shade. Veneers with 0.5 mm thickness tended to display the B1 shade, while veneers with 0.75 mm and 1.0 mm thickness primarily exhibited the B2 shade. The thickness of the laminate veneer and background shade significantly modified the original shade of the zirconia veneer. One-way analysis of variance was performed and a Kruskal–Wallis test was used to determine the significance between the three veneer thicknesses groups. The results indicated that the thinner restorations showed higher values with the color imaging spectrophotometer, suggesting that thinner veneers may result in more consistent color matching. This study underscores the importance of carefully considering thickness and background shade when selecting zirconia laminate veneers, to ensure optimal color matching and overall aesthetic outcomes.

“…This approach allowed for effective communication of the prosthetically planned gingival architecture with the surgeon performing the procedure. A technique describing how to fabricate a 3D-printed overlay template to aid the placement of two implants in an edentulous mandible has been presented in the literature [ 28 ], and 3D-printed overlay tooth reduction guides have been advocated to minimize unnecessary reduction of flare-out or rotated teeth during veneer preparations [ 29 , 30 , 31 ].…”

3D-Printed Overlay Template for Diagnosis and Planning Complete Arch Implant Prostheses

et al. 2023

Dental implants are a reliable alternative to treating edentulism. In clinical situations where the dentition has been severely affected by partial edentulism, advanced wear, or periodontal disease, establishing important occlusal elements such as the occlusal plane, incisal guidance, and esthetics can be hard to visualize at the diagnostic stage without extracting teeth. Contemporary data-acquisition technologies such as 3D scanners and CAD/CAM systems permit the precise manufacture of highly complex devices applicable to any stage of restorative treatment. The present clinical report presents an alternative technique for evaluating the projected artificial tooth relationships, vertical dimension, and occlusal plane in patients with severely weakened dentition by using a 3D-printed overlay template.

“…Clinicians have a variety of ceramics to choose from when fabricating labial LVs, including lithium disilicate, feldspathic porcelain, leucite, zirconia, and combinations of these materials ( Afrashtehfar et al, 2015 , Jurado et al, 2021 , Jurado et al, 2022a , Jurado et al, 2022b ). Zirconia, due to its high mechanical properties and good esthetic results for crowns, is currently being used for LV restorations ( Alikhasi et al, 2022 , Lawson et al, 2019 ).…”
