Shear Bond Strength of Two Chemically Different Denture Base Polymers to Reline Materials

Abstract

The two chemically different denture base polymers showed different shear bond strength values to corresponding reline materials.

In Vitro Comparison of the Cytotoxicity and Water Sorption of Two Different Denture Base Systems

“…Since polymethyl methacrylate (PMMA) was introduced to dentistry in 1930s, it has been successfully used for fabricating removable dentures due to its low cost, adequate esthetic properties, and ease of manipulation . Nevertheless, contact allergies caused by released residual methyl methacrylate monomers and weak mechanical properties such as low impact strength and low fatigue resistance are disadvantages of the PMMA denture base . Furthermore, the lack of dimensional stability is an important deficiency of acrylic resins .…”

Clinical performance of a light-cured denture base material compared to polymethylmethacrylate—a randomized clinical study

“…A significant difference between the two denture resins VLCR and PMMA was shown with regard to the plaque coating. Though in this study only one VLCR material and one PMMA material was investigated, it is assumed that the results obtained are also valid for other materials of the same type, especially as all VLCR materials available rely on the same basic chemistry [12,15,16].…”

Shear Bond Strength of Denture Teeth to Two Chemically Different Denture Base Resins after Various Surface Treatments

“…However, in addition to the low impact strength and low fatigue resistance of PMMA, patient allergic responses to methyl methacrylate monomer (MMA) have led to efforts to produce new materials with better mechanical properties than PMMA . Thus, in the early 1980s, light‐activated urethane dimethacrylate (UDMA) resin was developed to eliminate contact allergies with its simple application …”
