Adaptation Accuracy of Two Different Denture Base Materials for the Completely Edentulous Maxillary Arch: An in Vitro Study

Background. In recent years, complete denture construction has been revolutionized using computer-aided designing and computer-aided manufacturing (CAD-CAM) technology. This clinical study compared the retention and denture base adaptation of 3D-printed complete dentures fabricated using dimethacrylate-based resins with a photoinitiator versus conventional complete dentures. Methods. Ten completely edentulous patients were nominated for this study. Each patient received two complete dentures. One complete denture was conventionally fabricated, while the other was digitally fabricated through 3D printing of dimethacrylate-based resins with a photoinitiator. Denture base adaptation for both dentures was evaluated using surface matching software. Denture retention was also evaluated using a digital force meter at the time of complete denture insertion (T0 ), after three months (T3 ) and six months (T6 ) of denture use. Results. Regarding adaptation (mean misfit values), a statistically insignificant difference was detected between the two differently fabricated complete dentures. In addition, comparable satisfactory retention values were observed for both conventionally fabricated and 3D-printed dentures; however, there was an insignificant increase in retention over time. Conclusion. 3D-printed complete dentures fabricated using dimethacrylate-based resins could be a promising alternative to conventionally fabricated complete dentures with satisfactory denture base adaptation and retention.

Background/aim The masticatory problem of removable complete dentures had been introduced by many researchers to be assisted by many recent technologies. Solving such issues advances self-patient satisfaction, confidence, and motivation. This study aimed to evaluate masticatory performance and patient satisfaction of metal-reinforced and CAD/CAM-fabricated acrylic resin mandibular complete dentures. Patients and methods Sixteen completely edentulous patients were divided randomly following a 1 : 1 allocation ratio into two groups; group I received maxillary and mandibular complete dentures constructed from acrylic resin reinforced with chrome cobalt framework and group II received maxillary and mandibular rapid prototype complete dentures (3D-printed) using the CAD/CAM technique. At baseline, 2, and 4 weeks, masticatory performance using the masticatory efficiency index and patient satisfaction using Borerrigter’s method of assessing patient satisfaction were evaluated at each interval for further statistical analysis using one-way analysis of variance test followed by Tukey’s post-hoc test for multiple comparisons and Pearson’s correlation coefficient between different variables. Results Regarding masticatory performance for each group, one-way analysis of variance revealed a significant difference between different intervals as a P value less than 0.05 with higher masticatory values for group II, while for patient satisfaction, it showed an insignificant difference for all satisfaction domains as a P value more than 0.05. The correlation between masticatory performance and overall patient satisfaction was calculated using Pearson’s correlation coefficient and revealed a moderate to strong, positive, significant correlation in both groups. Conclusion The masticatory performance and patient satisfaction of mandibular complete dentures constructed by the 3D-printed CAD/CAM method were higher than acrylic resin denture bases reinforced with chrome cobalt framework, denoting that the 3D-printed CAD/CAM method can be the primary clinical treatment option for completely edentulous patients despite its overall level of satisfaction, which requires additional follow-up investigations to pronounce the positive effect of CAD/CAM dentures.
