An In-Vitro Study to Assess the Effect on Flexural Strength of Two Different Ceramic-Veneered Sub-Structures with Four Variable Thickness

Abstract

Background:  Esthetic dentistry combines technical skill and artistic creativity to produce dental prostheses that restore function and enhance smiles. Over the years, dental materials have evolved from amalgams and gold alloys to advanced ceramics like zirconia, which offer superior aesthetics and strength. Porcelain-Fused-to-Metal (PFM) restorations, used since 1965, are durable but can compromise aesthetics due to light transmission issues. Zirconia ceramics, ideal for anterior and posterior restorations, combine strength and translucency similar to natural teeth. Advances in CAD/CAM and laser sintering technologies have improved the precision and durability of zirconia crowns. Understanding flexural strength, a material’s resistance to deformation, is crucial for durable and aesthetically pleasing restorations.
