This study evaluates prosthodontists' satisfaction and efficiency of custom tray fabrication methods in completely edentulous mandibular jaw patients. A digital workflow was established, incorporating 3D scanning for preliminary impressions, CAD for designing border extensions and ensuring uniform 3D space, and 3D printing for tray fabrication. Three methods were compared: CAD/3D printing, light-cured resin, and impression compound trimming. Prosthodontist satisfaction was assessed using a visual analog scale, and manual fabrication time was analyzed. Dislocation tests were performed to evaluate tray retention. The CAD/3D printing method achieved the highest satisfaction across most parameters (P＜0.05) , the best stability and retention (P＜0.05), and significantly reduced manual fabrication time (P＜0.05). The light-cured resin method showed moderate performance, while the impression compound trimming method scored lowest. The CAD/3D printing technique enhances satisfaction, precision, and efficiency, demonstrating significant potential for optimizing prosthodontic workflows. Further exploration in broader clinical applications is recommended.This study investigated a digital custom tray fabrication method using 3D scanning for preliminary impression data acquisition, CAD technology for designing border extensions and uniform 3D space, and 3D printing for tray production. Prosthodontist satisfaction and fabrication time were evaluated to compare this method with conventional techniques, aiming to develop an accurate, time-efficient, and labour-saving approach for custom tray fabrication for complete dentures.
