Abstract
Objective The new type of zirconia materials and dentin was bondTM d with different adhesive systems, using different types of LED curing lights. By comparing the shear strength, to provide certain theoretical reference for the choice of clinical indications, adhesives systems and curing lights of the new type of restoration. Methods According to the unified standard, maxillary incisors in vitro were selected as experimental samples. Prepared and scanned post space, new type of zirconia post was made by CAD/CAM. Randomly divided into 6 groups, post was respectively bondTM d using 3 kinds of adhesive systems (Panavia F, Multilink N, NX3-Nexus) and 2 kinds of LED lights (ordinary, VALO). Then the samples were horizontally cut into a 1 mm slice. The slices were released in the universal mechanical test machine, the shear strength of each group was analyzed by SPSS 17.0. Results The shear strength of Panavia F was better than that of Multilink N and NX3-Nexus, using the ordinary LED curing light (P ＜ 0.05). Panavia F also had higher shear strength than the other two adhesive systems, using VALO LED curing light (P ＜ 0.05). There was no significant difference in shear strength between the ordinary and VALO light, using the same adhesive systems (P＞ 0.05). Conclusion The adhesion strength of Panavia F is better than those of Multilink N and NX3-Nexus, using different types of LED curing lights. There is no significant difference in adhesion strength between VALO and ordinary LED curing light, the VALO LED curing light can significantly reduced the operating time by the side of the chair.关键词
