Comparative Analysis of the Mechanical Properties and Biocompatibility between CAD/CAM and Conventional Polymers Applied in Prosthetic Dentistry

Abstract

Modern media often portray CAD/CAM technology as widely utilized in the fabrication of dental prosthetics. This study presents a comparative analysis of the mechanical properties and biocompatibility of CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing) polymers and conventional polymers commonly utilized in prosthetic dentistry. With the increasing adoption of CAD/CAM technology in dental laboratories and practices, understanding the differences in material properties is crucial for informed decision-making in prosthodontic treatment planning. Through a narrative review of the literature and empirical data, this study evaluates the mechanical strength, durability, esthetics, and biocompatibility of CAD/CAM polymers in comparison to traditional polymers. Furthermore, it examines the implications of these findings on the clinical outcomes and long-term success of prosthetic restorations. The results provide valuable insights into the advantages and limitations of CAD/CAM polymers, informing clinicians and researchers about their suitability for various dental prosthetic applications. This study underscores the considerable advantages of CAD/CAM polymers over conventional ones in terms of mechanical properties, biocompatibility, and esthetics for prosthetic dentistry. CAD/CAM technology offers improved mechanical strength and durability, potentially enhancing the long-term performance of dental prosthetics, while the biocompatibility of these polymers makes them suitable for a broad patient demographic, reducing the risk of adverse reactions. The practical implications of these findings for dental technicians and dentists are significant, as understanding these material differences enables tailored treatment planning to meet individual patient needs and preferences. Integration of CAD/CAM technology into dental practices can lead to more predictable outcomes and heightened patient satisfaction with prosthetic restorations.

Fracture Resistance Analysis of 3D-Printed and Prefabricated Artificial Teeth for Removable Dentures

“…By continually refining the design and composition of denture teeth, manufacturers aim to address the persistent challenges associated with prosthodontic treatment, ultimately improving patient satisfaction and quality of life [20]. As research and technology progress, the evolution of denture teeth holds promise for revolutionizing the field of prosthodontics, paving the way for more resilient and functional dental prostheses.…”

In Vitro Study of the Surface Roughness, Hardness, and Absorption of an Injection-Molded Denture Base Polymer, Manufactured under Insufficient Mold Solidification

“…Several significant drawbacks associated with polyamide dentures include the propensity for plaque accumulation and substantial alveolar bone resorption in edentulous regions. These issues stem from the absence of a conventional removable partial denture design, which is a primary factor contributing to the limited duration of oral use for polyamide dentures [50]. Plaque buildup poses a concern for oral hygiene and can lead to various dental problems, while the high degree of alveolar bone resorption in areas lacking teeth compromises the structural integrity of the denture's foundation.…”
