PURPOSE Purpose of this study was to evaluate effect of two surface treatments, sandblasting and monomer treatment, on tensile bond strength between two long term resilient liners and poly (methyl methacrylate) denture base resin. MATERIALS AND METHODS Two resilient liners Super-Soft and Molloplast-B were selected.Sixty acrylic resin (Trevalon) specimens with cross sectional area of 10×10 mm ...

acrylic base resins are widely used in orthopedics and dental surgery. it is generally accepted that due to the incomplete conversion of methyl methacrylate (mma) monomer to the polymer form during polymerization of the resin, some mma monomers remain in the hardened material. mma monomer has been reported to cause abnormalities or lesions in several organs of animals. study of the literatures ...

INTRODUCTION Acrylic bone cements, used in arthroplasty, incorporates contrast media to make them radiopaque and visible on X-ray images. However, today’s particulate contrast media cause three disadvantages to the acrylic bone cement, namely; third body wear, decreased mechanical properties and reduced biocompatibility. Iohexol hexaacetate (IHA) is a new iodide based non-ionic contrast medium,...

The degree of polymerization of an acrylic resin repair material, as established by residual monomer estimation, was compared using three different polymerization methods, i.e. bench-cure, hydroflask-cure and microwave irradiation cure. The repair strength of a conventional heat-polymerized resin was then assessed following repairs using each of these three methods. The lowest level of residual...

Microparticles composed of (meth)acrylic acid, potassium (meth)acrylate, and trifunctional pentaerythritol were prepared using a thermally initiated free radical precipitation polymerization in ethyl acetate. The particle synthesis method was investigated, and the structure and morphology of the microparticles was evaluated using Fourier transform infrared spectroscopy and scanning electron mic...

In the simplest case, vinyl monomers are named by using the prefix poly in front of the monomer name, e.g. polyethylene. When a monomer name consists of more than one word, or if the name is preceded by a number or letter, the monomer name is placed in parentheses after the word poly, e.g. poly(acrylic acid) or poly(methyl methacrylate). In general, common names of monomers are used rather than...
