Abstract
Background: The clinical effectiveness of dental restorations is greatly influenced by the materials used in them. The advent of CAD-CAM (Computer-Aided Design and Computer-Aided Manufacturing) technology has revolutionized the world of dental materials and created new avenues for prosthetic and restorative dentistry.
Objective: This systematic study evaluates CAD-CAM dental materials in terms of their clinical uses and mechanical characteristics. It aims to assess how these characteristics affect prosthetic and restorative dentistry performance.
Method: A thorough literature search was carried out utilizing the Cochrane Library, PubMed, Scopus, and Web of Knowledge databases. The main emphasis of the inclusion criteria for CAD-CAM dental materials was on studies that addressed clinical indications, mechanical qualities (such as flexural strength, hardness, and elastic modulus), material composition, and optical properties. This specific focus ensured that the selected studies were directly relevant to the field. Systematic and narrative evaluations, as well as in vitro and in vivo investigations, were considered. Out of the initial 564 recognized papers, 63 were found appropriate for analysis using a selection method that adhered to the PRISMA principles.
Result: The review revealed that CAD-CAM materials demonstrate diverse mechanical properties, contributing to their adaptability in clinical applications. Approximately 60% of studies highlighted the continued use of traditional materials like feldspathic ceramics, while around 40% indicated a growing adoption of newer materials, such as resin block composites, for permanent restorations. Mechanical properties such as strength and durability were critical, with over 70% of materials providing suitable for various dental procedures, including inlays, onlays, crowns, and veneers. The extracted data was arranged using reference management software (e.g., EndNote, Zotero).
Conclusion: Within the limitations of this systematic review, CAD-CAM materials offer significant advantages in restorative and prosthetic dentistry due to their superior mechanical properties. These materials enhance the quality and longevity of dental restorations and expand the range of clinical applications.
