Brief Summary

In this study we are going to compare dimensional accuracy of maxillary complete denture base fabricated by using rapid prototyping method and conventional method. We hypothesize that both techniques do not significantly differ from each other

Study Arms (2)

Group R

EXPERIMENTAL

Rapid Prototyping method of fabrication of complete denture: the master casts will be scanned using DENTAL WINGS eco-scan 3, using laser technology for scanning, after spraying the stainless steel pins with scanning spray to be recorded into the denture base. Virtual model will be obtained for fabrication of denture bases. Denture base will be designed and modified on the virtual model, then it will be printed using ZENITH-3D Printer using Urethane acrylate oligomer based photo-polymerized resin.

Device: Rapid Prototyping method of fabrication of complete denture

Group C

ACTIVE COMPARATOR

Conventional method of fabrication of complete denture: Self-cured acrylic resin trial denture bases will be constructed on the obtained master casts, then processing of the final denture bases by conventional clamping method cured by long curing cycle (74º C for 8 hours) using heat-cured poly-methyl methacrylate (PMMA) resin material. The position of the pins will be recorded into the denture bases so that the linear changes could be measured.
