Development of a new temporary luting agent consisting of PEMA and eugenol--residue ratio and bond strength of luting cements for abutment materials.
PEMA- and eugenol-based trial agents (PE 1.0, PE 1.6) possessed the requisite dental engineering properties that satisfied the requirements for temporary luting agents. To assess their clinical applicability, this study examined the following properties after the trial agents were removed: their residue ratios on the abutment surface and the bond strengths of resin-modified glass ionomer cement and resin cement for the abutment materials. The residue ratio of PE 1.0 on the abutment material after temporary restoration removal was lower than those of comparable temporary luting agents (polycarboxylate cement type, zinc oxide-eugenol cement type), and no residue was recognized for PE 1.6. On bond strength, those of the resin-modified glass ionomer cement and resin cement for the resin core and bovine dentin surface after the removal of trial agents tended to be the same or increase in comparison to commercial temporary luting agents. In conclusion, results of this study suggested that the trial agents were suitable for clinical use.
