Factors that contribute to the successful fabrication of CAD-CAM complete dentures

Complete denture (CD) fabrication has changed dramatically with the introduction of computer-aided design and computer-aided manufacture (CAD-CAM) technologies. These techniques provide benefits including shorter chair times, better material qualities, and cost effectiveness. This systematic study assessed the variables that affect the successful manufacture of CAD-CAM CDs and examined the results and difficulties that follow. Using a thorough approach based on the patient population, intervention, comparison, and outcome framework, manual mining and citation mining were added to electronic searches performed on Google Scholar and PubMed. Studies and clinical reports assessing the clinical outcomes of CAD-CAM CDs were included. Several factors that might affect the performance of CAD-CAM CDs were examined: bond strength, precision, CAD-CAM polymers, and comparisons between digital and traditional dentures. Also examined were issues and mistakes related to clinical performance, time management, denture tooth features, surface qualities, digital workflow, cleaning processes, burs effects, impression techniques, strength, tissue adaptability, patient satisfaction, and retention. The results showed that, albeit with certain drawbacks, CAD-CAM dentures are stronger, more true to size, and fit better than three dimensionally printed options. Overall, digital dentures, as a potential treatment option, are clinically effective, require fewer visits, and improve patient information management. However, problems including speech problems, medical complications, and cosmetic flaws still exist. Before digital dentures become widely accepted, it is imperative to address these limitations. This study highlights the potential of CAD-CAM CDs and identifies areas for further development in clinical practice, offering insightful information about the present status of the technology.
