Përdorimi i teknologjisë CAD/CAM në punimin e urave nga zirkoni

The aim of this case report was to demonstrate the clinical and laboratory workflow for the fabrication of a zirconia-ceramic bridge in the anterior region of the maxilla using CAD/CAM technology (KaVo Everest system). The patient had lost a central incisor due to a vertical root fracture, and after analyzing various treatment options, the fabrication of an all-ceramic bridge was selected. The clinical procedure included precise tooth preparation according to the principles of periodontal preservation and structural stability, application of the double-cord technique for optimal gingival retraction, and corrective impression-taking using addition silicones. The laboratory procedures involved the fabrication of a scanned working model, virtual design of the bridge framework in 3D CAD software and milling of the framework from a soft zirconia-oxide block. Additional coloration and sintering were performed to achieve a high level of esthetic quality. The final prosthetic restoration was completed with veneering ceramic layering, with shade determination using a combination of a classical shade guide and a digital Spectroshade device. It was concluded that the use of CAD/CAM technology enables high precision, material biocompatibility, and superior esthetic outcomes while significantly reducing laboratory processing time, highlighting the importance of integrating digital technologies into contemporary prosthodontic practice.
