o bjectives: heat-polymerized acrylic resin has been the most commonly used denture base material for over 60 years. however, the mechanical strength of acrylic resin is not adequate for long-term clinical performance of dentures. consequently, fracture is a com- mon clinical occurrence, which often occurs in the midline of denture base.this study aimed to evaluate the efficacy of cold cure and...

rutting in asphalt concrete is a very common form of distress in asphalt concrete pavement which unfortunately has been incurable to date. one of the prime reasons of rutting is attributed to the behaviour of asphalt binder at elevated temperature. this study has investigated the performance of polypropylene fibres modified asphalt concrete mix against rutting. two types of asphalt concrete sam...

OBJECTIVE The purpose of this study was to compare the effects of mechanical polishing (MP) and chemical polishing (CP) on the average surface roughness (Ra) of heat-cured (HC) and light-cured (LC) denture base acrylic resins. METHODS A total of 120 specimens (30 × 15 × 3 mm) were prepared from one HC and one LC acrylic resin. To remove nodules and gross surface irregularities, all specimens ...

Water based inorganic alkali silicate binder of zinc rich primer was modified by adding acrylic resin derivatives. Several series of primer coatings were formulated by adding 5, 10 and 15 wt of acrylic and acrylic/styrene copolymer to potassium silicate binder and used as binder in zinc rich coatings. The formulated primers were applied on low carbon steel plates and the corrosion protection pr...

We evaluated the microstructure of the edges of currently available foldable intraocular lenses (IOLs). The methodology used assisted an IOL manufacturer (Hoya, Japan) to optimise the edge profile of its lenses. Ten designs of hydrophobic acrylic, six designs of silicone and 24 designs of hydrophilic acrylic IOLs were imaged under scanning electron microscopy (SEM), and the photographs were imp...

STUDY DESIGN: An experimental pilot study using an acrylic interbody cage in a dog cervical spine fusion model. OBJECTIVE: To compare bony fusion in autologous bone grafting with a novel acrylic cage in terms of preservation of disc height, biomechanical properties, and histologic characteristics. SUMMARY OF BACKGROUND DATA: Degenerative diseases of cervical intervertebral discs are commonly tr...

Global increase in patients seeking orthodontic treatment creates a demand for the use of acrylic resins in removable appliances and retainers. Orthodontic removable appliance wearers have a higher risk of oral infections that are caused by the formation of bacterial and fungal biofilms on the appliance surface. Here, we present the synthetic route for an antibacterial and antifungal organicall...

Quaternary ammonium methacryloxy silicate (QAMS)-containing acrylic resin demonstrated contact-killing antimicrobial ability in vitro after three months of water storage. The objective of the present double-blind randomised clinical trial was to determine the in vivo antimicrobial efficacy of QAMS-containing orthodontic acrylic by using custom-made removable retainers that were worn intraorally...

The purpose of this study was to develop an acrylic resin with antifungal properties by leveraging the photocatalytic activity of apatite-coated titanium dioxide (Ap-TiO2). Candida albicans was used for antifungal activity assay of the specimen plates under ultraviolet A (UVA) with a black light source. Statistically significant decreases in cell viability in acrylic resins containing 5 wt% and...

Acrylic-based coatings are produced in formulations to suit all the major markets within the coatings industry. Industrial, decorative, printing inks, powder, and wall coverings are some of the market areas where acrylic-based coatings are widely used. Water emulsion and film-forming acrylic-based coatings are of particular importance due to their relative high performance and extremely low vol...
