Purpose: To perform a systematic review that provides an overview of the current literature on the most efficient surface treatment method for repairing three-dimensional (3D) printed dentures compared to conventional dentures and computer-aided design/computer-aided manufacturing (CAD/CAM) milled dentures.
Materials and methods: The review followed the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) guidelines. Electronic searches were done via Ovid, PubMed, ScienceDirect, Scopus, and Web of Science for studies reporting on denture base repair with surface treatment. Inclusion criteria were the English language with full text and studies that included surface treatment. Exclusion criteria were studies that did not assess the performance of surface treatment in denture repair. A quality assessment and selection of full-text articles were performed according to Consolidated Standards of Reporting Trials (CONSORT).
Results: A total of 531 articles were initially identified and screened. After applying inclusion and exclusion criteria, 14 articles were selected for the final analysis. Around 10 of the included studies utilized three-point flexural bending tests to test the flexural strength (FS) of the repaired samples. Four studies used the shear test. Around 12 studies used conventional resins and two studies used 3D-printed denture base resin specimens. Nearly 11 studies performed posttest analysis.
Conclusion: Studies have shown various promising enhancements in repair strength with both mechanical and chemical surface treatment. However, more research is required specifically on 3D printed and CAD/CAM dentures and to compare mechanical and chemical surface treatments or combinations of both, for it to become a more established treatment option.
