Lee (2001) reported that chopped strands of fibers 3 mm sized added to the heat-polymerized acrylic resins
denture base more than 3% can significantly increase the modulus of elasticity.
* To evaluate and compare the marginal accuracy of provisional crowns fabricated using chemically polymerized Bis-GMA composite resin (two paste auto mix system), light polymerized UDMA composite resin (single paste system), and chemically polymerized PMMA acrylic resin
(powder-liquid system) by the direct technique.
Characterization of Acrylic Resins
. In order to evaluate the distribution status of Cloisite 30B on the resin, transmission electron microscope (TEM) images were recorded on a Philips CM-120, working at an accelerating voltage of 100 kV.
Key Words: Denture fracture, Acrylic resin
Different methods such as gas chromatography, infrared spectrometry and chemical detection have been described to evaluate the levels of residual MMA monomer.2-4 HPLC is popular in analytical chemistry as it is a nondestructive method that enables simultaneous analysis of various substances and provides correct estimates of the degree of residual monomer in acrylic resins
. 12 As far as the scientific data on the amount of unreacted residual monomer released from denture based polymers is concerned, there is limited date available on leaching of residual monomer after one hour time interval.
(2) To comparatively analyze the efficacy of the four different denture cleansers in removing tea stains from acrylic resins
Reitz, "The use of microwave energy for processing acrylic resins
," The Journal of Prosthetic Dentistry, vol.
Type of resins: Acrylic resins
; acrylicstyrene; alkyd resins; emulsions; epoxy hardeners; high-solid resins; polyester resins; silicone polyesters; TGIC resins; urethane/polyurethane resins; water-thinned resins
ADH exists stably in the prepared self-crosslinkable water-soluble acrylic resins
because of the inhibition of ammonia.
The storage medium had an effect on the micro-hardness of heat cure acrylic resins
. Group 4 showed the most reduction in the hardness value which was followed by Group 3.
In addition to alkyd and acrylic resins
, the company produces phenolic, melamine, polyurethane, and polyester resins; resinate; pitch-derived resins; and modified oils.
(5) Pastes containing chloroform cause increased wear due to chemical solubility of acrylic resin
