Assessment of Conventionally and Digitally Fabricated Complete Dentures: A Comprehensive Review

CAD/CAM technology is gaining popularity and replacing archaic conventional procedures for fabricating dentures. CAD/CAM supports using a digital workflow reduce the number of visits, chair time, and laboratory time, making it attractive to patients. This study aimed to provide a comparative review of complete dentures manufactured using CAD/CAM and conventional methods. The PubMed/Medline, Science Direct, Cochrane, and Google Scholar databases were searched for studies published in English within the last 11 years (from 2011 to 2021). The keywords used were computer-engineered complete dentures, CAD/CAM complete dentures, computer-aided engineering complete dentures, and digital complete dentures. The search yielded 102 articles. Eighteen relevant articles were included in this review. Overall, computer-engineered complete dentures have several advantages over conventional dentures. Patients reported greater satisfaction with computer-engineered complete dentures (CECDs) due to better fit, reduced chair time, shorter appointments, and fewer post-insertion visits. CAD/CAM allows for precision and reproducibility with fewer procedures compared to conventional dentures. Polymethyl methacrylate is used as the denture base material for conventional dentures. For CECDs, the resin can be modified and cross-linked to improve its mechanical properties. The advantages of CECDs include a reduced number of appointments, saving chairside time, a digital workflow allowing easy reproducibility and greater patient satisfaction with a better fit.

Automated summary

CAD/CAM technology is increasingly used in the fabrication of dentures, offering advantages such as better fit, reduced appointments, and improved patient satisfaction. Computer-engineered complete dentures (CECDs) have distinct material and manufacturing processes compared to conventional dentures. Patients reported higher satisfaction with CECDs, and CAD/CAM technology enables precision and reproducibility in the fabrication process.
