説明
To evaluate fracture toughness of adhesive resin cements, Notchless Triangular Prism Fracture Toughness Test (NTP) was applied and examined whether Adhesive prism and its adhesive gap conditions correspond to the evaluation method of fracture toughness test. Adhesive prism was composed of the adhesive material sandwiched between two metal triangular prisms at three kinds of gap (0.5, 1.0, 2.0 mm). Superbond C& B (SB) and Panavia Fluoro Cement (PV) were used as an adhesive material. Fracture phenomenon of adhesive surface was investigated using fractographical analysis, stress-strain curve analysis and maximum fracture strength. Results were as follows. 1. NTP using adhesive prism showed proper fracture toughness values (K1c) of dental adhesive resin cements. 2. The different fracture phenomena were shown: 2.0 mm gap was cohesive fracture and 0.5 mm gap was adhesive fracture. 3. Zero point five mm gap showed the adhesive fracture and its K1c did not show significant difference between SB and PV. 4. There was no significant difference of K1c between PV20 (2.0 mm gap) and PVP (NTP prism made with PV).
