Current status of pour type denture base resins

Evaluation of the mechanical properties of different materials for manufacturing occlusal splints

“…19 Because of the amount of residual monomer in self-curing resin, it facilitates the formation of pores and impairs the mechanical properties of this group. 20 The mean Ra value of 0.1 µm found in this study for milled PMMA samples was similar to that found in another study, which found a value of 0.192 µm for the same variable. 10 Because there is no standardization in polishing, the roughness variable is quite inconsistent in the literature, resulting in divergent mean values.…”

“…The mechanical properties of self-curing resin samples are worse in most analyses (hardness, flexural strength, and elastic modulus) because this material contains more residual monomer, which affects their mechanical properties. 20 The polymerization method of samples made with self-curing acrylic resin was one of the study's limitations. The manufacturer recommends that polymerization be performed in a pressure cooker with 20 pounds of compressed air for 20 min.…”

Evaluation of the properties of a new pour denture base material utilizing a modified technique and initiator system

“…The lutopolymerizing repair material Croform, and the pour type material Provac, showed significantly lower equilibrium water uptake values and higher diffusion coefficients (P<0-01) compared with the heat-cured material Trevalon. These results are in good agreement with those of Bates et al (1977). The previous results can be explained as postulated by Jagger (1975).…”

Porosity, water sorption and solubility of denture base acrylic resins polymerized conventionally or in microwave

“…Similarly, the lowest water sorption results observed in M3 and M5 groups can be associated with a low degree of conversion values. Moreover, the highest solubility values found in the M3 group can be due to a higher residual monomer content 20 because it has been related to higher levels of solubility of acrylic resins 3 , 5 .…”
