title: Evaluation of the Elastic Properties of Thirteen Silicone Interocclusal Recording Materials.
abstract: Background.Addition silicones are popular as dental impression materials and are used in bite registration procedures.Objective.This study aimed to compare the postsetting elasticities and other mechanical properties of thirteen addition silicone interocclusal recording materials.Materials and Methods.The following materials were investigated: Colorbite D, Futar D, Genie Bite, Jet Blue Bite fast, Memoreg 2, O-Bite, Occlufast Rock, Omni-Bite Plus, Regidur i, Registrado X-tra, Regofix transparent, StoneBite, and Variotime Bite. Thirty specimens of each material were tested. The elasticities and strengths of the materials were measured with a universal testing machine, and computer software was used to determine theE-moduli, ultimate tensile strengths, and ultimate elongations of the specimens.Results.The results were subjected to statistical analysis using the Kruskal-Wallis test (p≤ 0.05). The statistics revealed that the meanE-modulus values varied significantly across the materials (p= 0.000) and were highest for the StoneBite and Registrado X-tra and lowest for the Regofix transparent. The ultimate tensile strengths were highest for the Regofix transparent and Registrado X-tra (p= 0.000) and lowest for the Jet Blue Bite fast and Memoreg 2 (p= 0.000). The elongation percentages at the point of breaking varied significantly across the materials (p= 0.000); the lowest value was observed for the StoneBite, whereas the Regofix transparent nearly doubled original length.Conclusions.The authors concluded that materials with the highE-moduli and great ultimate tensile strengths may be most useful clinically. Registrado X-tra and StoneBite best met these criteria.
