Measuring Quality of Life of Poly-amide Complete Dentures

July 27, 2017 updated by: Amr Magdy Ibrahim, Cairo University

Metal-reinforced Flexible Poly-amide Complete Denture Versus Heat-cured Poly-methyl Methacrylate in Terms of Oral Health Related Quality of Life; Randomized Clinical Trial

Polymethyl methacrylate have been used since 1937 as a gold standard for a denture base material because of its several advantages as; good esthetics, adequate strength, easy repair and simple processing techniques. As any material it has some problems as polymerization shrinkage, low impact and flexural properties and low fatigue resistance2. So polyamide was introduced into dentistry to be used as a denture base material in order to solve these problems. Polyamide denture base materials have some superior properties than PMMA as; High impact & flexural strength, excellent esthetics and less release of residual monomers4. Although being an advantage from the point of patient satisfaction, flexural property considered to be a contraindication for a denture base material.

The invistigators' trial is done in order to improve rigidity of a polyamide material as well as to improve oral health related quality of life in comparison to heat cured polymethyl methacrylate.
