Abstract
The purpose of this study was to develop a temporary luting agent with excellent handling and with suitable bond strength which, in addition, would leave less of a remnant after the removal of a temporary restoration from the abutment. The basic composition of the experimental material (PEE) was polyethylmethacrylate (PEMA) powder and eugenol oil. The powder/liquid ratio varied from 1.0 to 1.6. The controls used were commercial temporary luting cements. The follwing results were obtained; PEE 1.6 had high consistency, high film thickness and low water solubility compared with PEE 1.0〜1.4. No sighnificant difference was observed in bond strength between self-curing resin crown and stainless die abutment when comparing PEE 1.6 and the control after the thermal cycling test. Observations of the interface of the adhesion specimen showed that PEE 1.6 did not remain on the die abutment. From the results, it was concluded that PEE 1.6 was suitable for clinical use.
