简要总结
the aim of this crossover randomized controlled clinical trial is comparing retention of 3D printed maxillary complete dentures produced from thermoplastic impression trays and conventional acrylic impression trays.
The research hypothesis is that there is no difference in patient satisfaction and retention of dentures constructed from definitive impression using the conventional tray and the prefabricated thermoplastic tray

研究组 & 干预措施
Thermoplastic tray definitive impression
干预措施: complete denture (Device)
Conventional tray definitive impression
干预措施: complete denture (Device)
结局指标
主要结局
Maxillary complete denture base retention
时间窗: 2 weeks after denture insertion
A loop will be attached to each denture base at the position of geographic center using self cure acrylic resin and the retention will be measured by applying the forces perpendicular to the denture using Digital Force Meter Each base will be tested 3 times and the average will be calculated.
次要结局
- Patient satisfaction(2 weeks)
