One of the reconstructive choices for the completely edentulous patient is the placement of multiple implants and the fabrication of a fixed implant-supported complete denture. These patients experience an improvement in masticatory performance over patients who wear complete dentures. The fixed-implant complete denture consists of a metal bar with acrylic resin and denture teeth connected to i...

PURPOSE The aim of this study was to clarify the effect of addition of glass fibers and titanium dioxide nanoparticles to the conventional acrylic resin. The tested parameters were monomer release, deflection at fracture, flexural strength, flexural modulus, and toughness. The modified acrylic resin groups were compared to the conventional unmodified and high impact types. The correlation betwe...

This articles is comprised of two parts: a) an experimental investigation on the behavior of an acrylic gel under DC electric field and b) a physico - mathematical description.a) Gel rods made of poly [acrylamide-co-bisacrylamide] were partially hydrolyzed to different extents at pH 12 by teteramethylethylene diamine. Equlibrium properties of the resulting gels rods (water content,...

objective: studies have demonstrates that physical properties of denture base affect patient satisfaction and acceptance. thermal conductivity is among the most important properties of denture base influencing the sense of taste and gingival health. the conventionally used acrylic resin has a low coefficient of thermal conductivity. this study aimed to improve the thermal conductivity of acryli...

degradation of acrylic water base color from synthetic wastewater by the fenton process was performed. experiments were conducted on the sample containing 100 and 400 mg/l of acrylic water base color. the study was performed for searching optimum values of feso4 and h2o2 concentration, ph and temperature. the h2o2 requirement seems to be related to initial cod of the sample. feso4/ h2o2 ratios ...

A pilot study has shown that there is usually but not invariably a fall in systemic arterial blood pressure within 90 seconds of implanting acrylic cement into the femoral shaft during hip arthroplasty. There is usually no change in arterial blood pressure on implanting acrylic cement into the acetabulum. The observed hypotension may be due to absorption of monomer or additives into the circula...

At Saint Louis University Health Sciences Center, bi-ventricular assist devices were placed in a patient after failure to wean from bypass. These acrylic devices are known to be used for post cardiotomy failure. Acrylics and other plastics are used in extracorporeal circuitry. Plastics have been known to crack when exposed to certain chemicals and conditions. This case describes the use of ultr...

BACKGROUND AND OBJECTIVE Chemical cleansing by denture cleansers is first choice for denture plaque control. The most common problems while using denture cleansers are hardening, porosity, odor sorption, water sorption, solubility, and colour change, bacterial and fungal growth. Chemical cleansing procedures have been found to have an effect on the physical and mechanical properties of denture ...
