Abstract Aim: to evaluate and compare the retention as well as dentist and patient satisfaction of maxillary 3D-printed dentures fabricated from thermoplastic tray impressions to those made using conventional final impressions. Methodology: Eleven completely edentulous patients were recruited for this double-blind, randomized, crossover clinical trial. Participants were randomly assigned to receive dentures fabricated from either thermoplastic tray impression or traditional tray impression for two weeks before switching to the other pair. The investigators and participants were both blind to the group allocation. Outcomes assessed were maxillary denture retention patient and dentist satisfaction with dentures. The outcomes were measured at baseline, and 2 weeks after denture insertion. After crossover, a similar protocol was implemented. For statistical analysis, a paired sample t-test with α=0.05 was used. Results: The trial was successfully completed by all participants. No significant difference in peak retention values was measured between the two groups at baseline (p = 0.27) and 2-weeks after denture insertion (p = 0.55). However, after two weeks of denture insertion, there was a statistically significant increase in retention values for both the conventional tray impression technique (p = 0.016) and the thermoplastic impression technique (p = 0.022). According to the paired sample t-test, there was a statistically significant difference in overall patient satisfaction favoring dentures fabricated from the thermoplastic tray, recording 3.40 ±1.23 (p = 0.001). Additionally, there was no significant difference in overall dentist satisfaction with the denture in both studied groups. (p = 0.67) Conclusion: A simplified approach for maxillary denture fabrication using thermoplastic trays could have comparable outcomes with dentures made from conventional trays.
