Digital workflow in complete removable dentures: an integrative literature review

Abstract

Digital dentistry has been transforming clinical practice, especially in the
fabrication of complete removable dentures using CAD/CAM technology. This study,
through an integrative literature review, analyzed the advantages and disadvantages of
digital complete dentures compared to conventional ones. The digital workflow stages were examined — including intraoral scanning, computer-aided design, and fabrication
through milling or 3D printing — along with an assessment of the benefits and
limitations of each phase. The research was conducted using the PubMed, BVS, and
ResearchGate databases, covering publications from 2017 to 2024. After applying
inclusion and exclusion criteria, 30 articles were selected for the final sample. The
review concluded that digital dentures offer greater accuracy, improved patient comfort,
reduced clinical appointments, and the ability to store data digitally. Digital scanning
simplifies the workflow, although technical challenges still need to be addressed. The
choice between milling and 3D printing depends on the specific requirements of each
clinical case, as both techniques have their own advantages and limitations.
