چکیده

This study aimed to comprehensively evaluate the next-generation complete denture manufacturing systems that include the material engineering properties, printing procedures, and their effects on the mechanical properties, surface properties, and biological behaviors. An in vitro experimental study was conducted. The conventional heat-polymerized polymethyl methacrylate (PMMA), CAD/CAM-milled polymethyl methacrylate (PMMA), and additively manufactured denture resins were used in making full dentures. The characterization of the materials was carried out with respect to mechanical (flexural strength and fracture resistance), surface (surface roughness and microscopic morphology), and physicochemical (stability) tests. Biological performance was measured by the analysis of protein adsorption as well as microbial adhesion. Statistical analysis was performed to determine significant differences between manufacturing techniques. Computer-aided design and computer-aided machining (CAD/CAM) dentures showed significantly (p < 0.05) increased flexural strength (112.7 ± 7.5 MPa) and fracture resistance (1560 ± 110 N) compared to the conventional PMMA denture. CAD/CAM fabricated dentures had significantly lower surface roughness (0.28 ± 0.05 µm) than PMMA. Furthermore, there was a decrease in protein adsorption and bacterial adhesion in CAD/CAM dentures, indicating improved biological compatibility. The next-generation complete denture manufacturing systems are improved to the conventional fabrication techniques, in terms of material properties, surface finish and biological responses. The combination of new material engineering with digital manufacturing is a new trend towards more predictable and reliable performance, better durability and potentially better clinical outcome in complete denture restoration.
