Statement Of Problem:
Computer-aided manufacturing and computer-aided design (CAD-CAM) has been implemented less in complete removable prosthodontics because various factors affect the results and quality of complete dentures. Some clinical studies and systematic reviews have compared digitally fabricated complete dentures (DCDs) with conventional complete dentures (CCDs), but few have focused on the complications and number of postinsertion visits.
Purpose:
The purpose of this systematic review was to compare CCDs and DCDs in terms of complications and postinsertion visits by evaluating outcomes that included occlusion, retention, and patient discomfort. The goal was to provide insights into the clinical implications of using digital versus conventional techniques for denture fabrication.
Material And Methods:
Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), the question: "Is there a difference in complications and postinsertion visits when CCDs are compared with digitally printed complete dentures?" was addressed. Two independent electronic searches up to March 2024 were done in the PubMed, Google Scholar, and Embase databases. The risk of bias in each study was assessed by using the Cochrane risk of bias tool and the Newcastle-Ottawa scale.
Results:
Of 63 articles, 11 were included. Outcomes were grouped into different kinds of complications: occlusion, retention or stability, pain, and number of postinsertion visits. In terms of all 4 complications, some statistically significant differences were reported.
Conclusions:
The manufacturing technique for complete dentures influenced the number and type of complications. The digital technique showed a similar or greater number of follow-up visits, depending on the method used and the study design.
