Book Description
From almost the time dentistry achieved a professional status, there has been a constant search to obtain a denture base material of life like appearance, one that would not deteriorate in service. The introduction and use of acrylic resin as a denture base material since 1937 has revolutionized the dentistry in a big way. Since then no other material has been found that matches the appearance of the oral soft tissues with as great fidelity as acrylic resin. Heat cured acrylic resins are the most commonly used materials for denture base processing. It has fine esthetic properties, excellent color stability and can be used with a simple technique for the construction of dentures. Inspite of having all these advantages, dimensional inaccuracies have been a critical component in assessing in vivo performances of these materials. These changes have profound effect on Complete Denture Occlusion. Even minor changes can lead to severe discrepancies. Dimensional inaccuracies is still a major challenge for the Prosthodontist which need to be corrected for better results. The aim of this study is to search for such a Denture Base material which shows minimal inaccuracies.

Book Description
Poor adaptations of acrylic resin denture bases to the supporting tissues markedly decrease denture retention. Several denture base resin and processing techniques have been introduced to the profession, each claiming to produce a more accurate base. Microwave processing techniques has been introduced claims to minimize the dimensional changes.This purpose of this study was to compare the dimensional accuracy of three denture base resins when processed both by conventional water bath method and by use of microwave energy. Three Poly (MethylMethacrylate) heat cure resins selected for this study. These resins were processed by conventional water bath technique for 1 1/2 hours at 75 degree & half hour at 100 degree and by microwave energy for 3 mins at 500W. The measurements of acrylic resin denture base specimens were compared with the measurements of master metal die dimension keeping it as a standard measurement. The mean values of the difference in the points compared were calculated, & compared to each other to determine if there was a statistically significant difference between them at the 0.05 probability level using the students' independent test for pooled variances

Book Description
Denture bases are commonly made from acrylic resins, which were introduced by Dr. Walter Wright back in 1937. Among these, polymethyl methacrylate (PMMA) is the most commonly used. PMMA material is mostly processed by wet heat and compression molding techniques, which deliver dentures with acceptable mechanical properties. However, certain dimensional changes are known to occur in acrylic resin during or after its processing. These changes hold clinical significance because for better adaptation to oral tissues, denture base material must have dimensional accuracy during and after its processing. However, inaccuracies tend to occur due to unavoidable changes during fabrication such as thermal expansion on heating, contraction on cooling and polymerization shrinkage. The purported significance of this study is to find out the most suitable cooling procedure for achieving maximum dimensional accuracy following a standard heating cycle. This will lead to the fabrication of a denture which will have better retention, support, stability.
