The purpose of this study was to quantitatively evaluate the effect of staining solutions by spectrophotometric method on color stability of the commercially available acrylic denture base resins polymerized by different methods of cure, materials, and immersion periods. Commercially available heat cure resin (Travelon) and self cure resin (RR repair material) were selected for the study. In ca...

BACKGROUND Acrylic teeth have long been used in the treatment of a complete denture. One of the primary advantages of acrylic teeth is their ability to adhesively bond to the denture base resins. Although the bonding seems satisfactory, however, bond failures at the acrylic teeth and denture base resin interface are still a common clinical problem in prosthodontics. The purpose of this study wa...

Abstract—Solar water heating is a thermodynamic process of heating water using sunlight with the help of solar water heater. Thus, solar water heater is a device used to harness solar energy. In this paper, a modified solar water heating system (MSWHS) has been proposed over flat plate collector (FPC) and Evacuated tube collector (ETC). The modifications include selection of materials other tha...

Alkyd resins are amongst the most important and widely used resins in coating sectors. In this communication we report on preparation of alkyd resins emulsified by grafted acrylic resins on their fatty acid moieties. Both high-shear mechanical homogenizer and ultra-sonic sonicator were used step-wise to disperse the alkyd resin and acrylic based monomers in aqueous media. The resins are of nano...

BACKGROUND/AIM Acrylic-based resins are intensively used in dentistry practice as restorative or denture-base materials. The purpose of this study was to analyze the surface structure of denture base resins and the amount of released potentially toxic substances (PTS) immediately upon polymerization and incubation in different types of artificial saliva. METHODS Storage of acrylic samples in ...

OBJECTIVES The aim of this study was to compare the color stability of three acrylic based hard liners (Ufi gel hard, Dura-Liner II, Tokuso Rebase) and two silicone based soft liners (Ufi gel permanent, Molloplast B) by using the colorimeter. METHODS Sixty disc-shaped samples, with uniform size of 10 mm diameter and 2 mm in thickness were fabricated for each material. Thirty samples were made...

Objectives; This study was carried out to compare the posterior palatal base distortion of denture bases processed with ProBase Hot to those processed by conventional heat cure acrylic resin (Acrostone) before and after water immersion. Study design; Twenty waxed denture bases were prepared for U-shaped palatine arch form, ten for each denture base material. Waxed denture bases were flasked, pa...
