研究概览
简要总结
The purposes of this study are to compare the denture tooth movement, the amount of occlusal adjustment needed and the chairside time required for CAD-CAM and conventional dentures.
PICOT Format:
P: completely edentulous patients. I: Complete denture fabricated by digital light processing method. C: Complete denture fabricated by the conventional method.
O:
Primary Outcome: Denture tooth movement
Secondary outcomes:
- Amount of occlusal adjustments needed
- Chairside time T: Three months with a wash-up period of 2 weeks

研究组 & 干预措施
Conventional CD
A conventional Complete denture will be constructed and the amount of denture tooth movement will be measured
干预措施: Complete Denture (Other)
Rapid Prototyped Denture
A digital light processed denture will be constructed and the amount of tooth movement will be measured
干预措施: Rapid prototyped denture (Other)
结局指标
主要结局
The amount of tooth movement
时间窗: 8 months
The amount of tooth movement will be measured immediately after denture construction using the Geomagic surface matching software (Geomagic Control 2014; 3D Systems Inc.) Laser scan images of the denture obtained both after trial setup of teeth and of the final denture after being hydrated for 24 hours. Those images will be transferred into STL files that will then be superimposed using the global registration function of the software by finding 10,000 points in common between both pre and pot processing STL files. Measurements will be made at different points using the software and colour surface maps will be created using the 3D comparison function to display the amount and direction of tooth movement
