Accuracy of 3D Printed Complete Dentures Using Two Impression Techniques: RCT

Cairo University11 enrolled

Overview

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

Outcomes

Primary Outcomes

Maxillary complete denture base retention

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.

Time frame: 2 weeks after denture insertion

Secondary Outcomes

Patient satisfaction

patient satisfaction data will be collected through questionnaire and graded by Visual analogue scale for both study arms

Time frame: 2 weeks
