STATEMENT OF PROBLEM Two potential problems commonly identified with a denture base incorporating a resilient liner are failure of the bond between acrylic resin and soft liner material, and loss of resiliency of the soft liner over time. Since patients may drink different beverages, it is important to evaluate their effects on physical properties of soft lining materials. PURPOSE The objecti...

The image provided by Tomoya Takada and colleagues shows a cross-sectional SEM micrograph of acrylic denture base resin impregnated with nanodiamond (ND). This study aimed to evaluate the effect ND impregnation on thermal conductivity commercially available resins. It was found that maximum when small amount NDs. colors ND-impregnated resins were also compared using spectrophotometric measureme...

Objective. To investigate the influence of reproduction of different thickness and palatal rugae materials on complete dentures speech using Computerized Speech Lab (CSL) (spectrogram). Materials and Methods. Three completely edentulous male patients (aged 50-60 years) were selected for reading a paragraph. Twelve upper dentures were constructed, four for each patient. The patients' speech grou...

Despite the large number of studies addressing the effect of microwave polymerization on the properties of acrylic resin, this method has received limited clinical acceptance. This study evaluated the influence of microwave polymerization on the flexural strength of a denture base resin. A conventional heat-polymerized (Clássico), a microwave-polymerized (Onda-Cryl) and a autopolymerizing acryl...
