Specimens were mounted and loaded at a crosshead rate of 1 mm/min (0.5 mm/min for FT) with a universal testing machine until failure occurred. One-Way ANOVA was used to analyze data for statistical significance.Results: There was a statistical significance between the mechanical properties of the cements when comparing between the dispensing method. See table for results.Conclusions: Changing the dispensing method may alter the mechanical properties of resin-based cements. Easier is not always better. Clinical significance of these results are yet to be based cements. Easier is not always better. Clinical significance of these results are yet to be determined.Table(s):RelyXUnicem(Handmix)RelyXUnicem 2(Automix)Variolink II(Handmix)VariolinkEsthetic(Automix)PANAVIASA(Handmix)PANAVIASA(Automix)G-CEMCapsule(Automix)G-CEMLinkAce(Automix)FT (MPa.m1/2)0.780.811.05*0.70.80.760.441.03*CS (MPa)133160*202*169154196*124159*Disclosure Statement:The submitter must disclose the names of the organizations with which any author have a relationship, the nature of the relationship, and the clinical or research area involved.
