Comparison of Mechanical Properties, Physical Properties, and Biocompatibility of Four Different Denture Base Resins:...

Four new dental replacement base tars were evaluated in vitro to determine their mechanical qualities, authentic properties, and biocompatibility.

In this experiment, we employed SR Triplet HOT (a fiber-developed heat fix tar), Sunflex (a multipurpose force fix sap), Trevalon-Hello (a high-impact heat fix tar), DPI (a digital pigment imaging system), and a variety of other pigments and inks (normal power fix tar). For these models, the ISO specification 1567 for dental substitute base gums called for testing of flexural strength, hardness, impact strength, water sorption and dissolvability, and cytotoxicity.

All the strength and mechanical properties tested had a statistically significant difference when intergroup analysis was performed.

The exceptional physical and mechanical capabilities of the Sunflex denture base resin, together with its biocompatibility with oral tissues, make it a good candidate for use as a denture base material in routine clinical practice.
