| Summary: | Background:
“By making entire denture fabrication more efficient and accurate, computer-aided design and manufacturing (CAD/CAM) technology has changed prosthodontics forever.” The purpose of this research was to compare the correctness of full denture bases made using CAD/CAM technology to those made using more traditional methods.
Materials and Methods:
Thirty edentulous patients were randomly selected and divided into two groups: Group A (conventional denture fabrication) and Group B (CAD/CAM-based denture fabrication). Standardized impressions and jaw relations were recorded for both groups. For Group A, denture bases were fabricated using traditional techniques involving wax patterns and processing with heat-cured acrylic resin. Denture bases for Group B were created with CAD software and manufactured with CAM machining. A computerized 3D scanner was used to measure adaptation and fit, and inconsistencies were analyzed at 10 predetermined sites to establish accuracy. A paired t-test was used for statistical analysis, and a significance level of P < 0.05 was selected.
Results:
The mean adaptation discrepancies were significantly lower in Group B (CAD/CAM) at 0.15 ± 0.02 mm compared with Group A (conventional) at 0.45 ± 0.05 mm (P < 0.001). In addition, the marginal fit was superior in the CAD/CAM group, with 90% of the samples showing discrepancies below 0.2 mm, compared with 65% in the conventional group. Patient satisfaction scores were also higher in Group B (mean: 8.5/10) versus Group A (mean: 6.8/10).
Conclusion:
CAD/CAM technology significantly enhances the accuracy and fit of complete denture bases compared with conventional fabrication techniques. The improved precision of CAD/CAM dentures may lead to better clinical outcomes and increased patient satisfaction. Incorporating CAD/CAM technology in denture fabrication is recommended for achieving optimal prosthodontic results. |
