Abstract :
Objective: The rise in aesthetic expectations and technological progress has significantly improved communication between dental technicians and dentists. The clinician's choice of color is vital for aesthetic success in restorations, as tooth color results from light interacting with dentin and enamel. Ceramic materials used in restorations must mimic these tissues to ensure color harmony. Adequate porcelain thickness is crucial for both aesthetic appeal, by matching the natural tooth color, and clinical durability. Studies recommend a minimum thickness of 1.5 mm for metal-supported porcelain restorations to meet aesthetic and functional requirements.
Materials and Methods: This study analyzed A2-colored restorations processed in the same furnace and returned from clinics to ensure standardization. Measurements from the buccal and occlusal surfaces provided average values. Porcelain thickness was measured using an HW-300S thickness gauge, with statistical analysis conducted via SPSS 20.0.
Results: The study included 26 anterior, 26 premolar, and 27 posterior crowns. Anterior buccal thickness averaged 1083.07 μm, premolar 1413.46 μm, and molar 1496.48 μm, showing a trend of increasing thickness from the front to the back of the mouth. However, molar thickness was less than expected, highlighting a potential discrepancy in aesthetic and functional design.
Conclusion: While porcelain thickness generally increased from anterior to posterior regions, unexpected variations suggest the need for careful consideration of both aesthetic and clinical factors in restoration design..
