Evaluation of Chewing Efficiency of Conventional Complete Denture in Comparison to Reinforced Poly Amide Denture

Not Applicable

• Conditions: Mouth, Edentulous
• Interventions: Other: polyamide; Other: heat cured acrylic resin

• Registration Number: NCT03391063
• Lead Sponsor: Cairo University

Brief Summary

the trial is done in order to reinforce polyamide to improve its modulus of elasticity to be able to use it as a denture base material in all clinical cases
