Background: Traditionally for decades most oral maxillofacial prosthesis were fabricated using heat cured acrylic resin with or without Co-Cr metal base, however, recently polyamide materials that are processed thermally not chemically have been widely promoted for use as the perfect alternative to conventional hard acrylic dentures. The aim of this study was to assess the reaction of human mes...

AIMS Present study aimed at evaluating the colour stability and flexural strength of flexible denture base materials (Valplast) and Polymethyl methacrylate (PMMA) denture base material (Meliodent) processed by two different methods (Injection moulding and compression moulding) after immersing them in three different denture cleansers with acidic, basic and neutral PH. METHODS AND MATERIALS To...

UNLABELLED Complete dentures often fracture during normal masticatory function. The reason could be due to the shape of the palate, i.e. deep, medium or shallow palatal vault. This in vitro study was performed to determine the relationship of palatal vault depth and flexural strength of two different permanent denture base resins. Edentulous maxillary casts of patients were collected from the d...

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...

Six thermoplastic resins and conventional acrylic resin were examined to characterize their mechanical and physical properties, water sorption, solubility, flexural strength, modulus of elasticity, tensile strength and color stability. Thermoplastic resins for non-metal clasp dentures exhibiting low water sorption and solubility offer hygienic advantages. Since they have a low modulus of elasti...

PURPOSE The bond strength of soft denture liner to a recently introduced denture base resin after thermocycling has not been compared to traditional denture base materials. The objective of this study was to investigate the effects of thermocycling on the tensile bond strength of soft denture liners to two chemically different denture base resins, polymethyl methacrylate (PMMA) and urethane dim...

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...
