The Esthetic Outcomes of Different Dental Ceramic Systems:(Review Artical)
Abstract
Background: The need for aesthetically pleasing prostho-dontic restorations has led to the advancement of all-ceramic materials as a viable alternative to porcelain-fused-to-metal systems. Aim of Work: This article critically examines the existing body of research on modern all-ceramic materials and systems, with a specific emphasis on their chemical composition and qualities. Additionally, it offers practical clinical guidelines for their use. Methods: The methods used in this study involve a com-prehensive review and analysis of the existing literature. Results: The study highlight the presence of glass-matrix ceramics, polycrystalline ceramics, and newly developed ma-chinable materials such as all-zirconia and resin-matrix ceram-ics. The unique characteristics of zirconia, such as its ability to toughen via transformation, its ability to stabilize the crys-talline structure, its susceptibility to disintegration at low tem-peratures, and the variables that influence its aging process, are highlighted. Conclusion: This article also discusses the advantageous qualities of resin-matrix ceramics, including a modulus of elas-ticity comparable to dentin, shock-absorbing capabilities, and great durability and fracture resistance.
