CAD–CAM Complete Dentures Manufactured Using Additive and Subtractive Manufacturing Techniques: A Feasible Clinical Approach for Managing Geriatric Patients With Advanced Residual Ridge Resorption

Edentulous geriatric patients represent a challenging clinical scenario for complete denture therapy. Factors including atrophic alveolar ridges, cognitive impairments, and anxiety are common and can complicate complete denture therapy. Computer-aided design and computer-aided manufacturing (CAD-CAM) technologies offer different workflows for fabricating complete dentures. This clinical case report series describes two digital workflows used for the fabrication of digital complete dentures. These procedures reduced the number of appointments and expedited manufacturing and delivery. The techniques presented require three to four appointments, fewer appointments compared to the traditional protocol used for complete dentures.
