Interventions
3D-printed ODYX-CR ceramic-filled resin
The ODYX-CR restorations will be fabricated using digital light processing (DLP) 3D printing; restorations will be adhesively cemented using preheated resin composite following the respective manufacturer's recommended surface-treatment protocols. Clinical performance will be evaluated at baseline (24 hours), 6, 12, months using Fédération Dentaire Internationale (FDI) clinical criteria, including functional, biological, and esthetic properties.
CAD/CAM-milled lithium disilicate ceramic
The comparator restorations will be fabricated by milling lithium disilicate CAD/CAM blocks. Both restorations will be adhesively cemented using preheated resin composite following the respective manufacturer's recommended surface-treatment protocols. Clinical performance will be evaluated at baseline (24 hours), 6, 12, months using Fédération Dentaire Internationale (FDI) clinical criteria, including functional, biological, and esthetic properties.
