Abstract:
Background:In the field of oral and maxillofacial prosthetics, implant-supported or tooth-supported prostheses have been proven to be an effective treatment option for patients with partial edentulism. However, complete dentures remain the sole treatment option for fully edentulous patients. Over the past decade, the use of CAD/CAM technology for fabricating complete dentures has increased substantially, leading to a growing number of studies comparing conventional complete dentures with those produced using CAD/CAM. In our country, however, there is a scarcity of research comparing the retention of maxillary complete dentures fabricated by conventional and CAD/CAM methods.
Aim:To compare the retention of maxillary complete dentures fabricated by CAD/CAM and conventional methods.
Materials and Methods:This study was conducted using a clinical trial design. The research was carried out at the Department of Prosthodontics, School of Dentistry, Mongolian National University of Medical Sciences (MNUMS), utilizing the Digital Technology Laboratory. The retention of 15 maxillary complete dentures fabricated by CAD/CAM and conventional methods was measured using a force gauge (AMF500). Statistical analysis was performed using SPSS version 26.0, and differences were considered statistically significant at p<0.05.
Result:The mean retention of maxillary complete dentures fabricated by the conventional method (8.85±9.10N) was higher than that of dentures fabricated by the CAD/CAM method (4.95±2.57N). To assess the difference between the two fabrication methods, the Wilcoxon Signed Ranks Test was performed. The results showed Z=-2.045, p=0.041 (p<0.05), indicating that the retention of conventional dentures was statistically significantly higher than that of CAD/CAM dentures.
Conclusion:The retention of maxillary complete dentures fabricated by the conventional method was statistically significantly higher than that of dentures fabricated by the CAD/CAM method.
