Abstract
Objective:To investigate the effect of FiltekTMZ250 and Solitaire 2 two different composite resins on the curing depth and bond strength of dental implant.Method:The factorial design with three factors, such as resin (2 levels),irradiation distance (3 levels),irradiation time (3 levels),and so on,144 curing depth specimens were prepared,and 18 combinations were made,the curing depth was measured.The design of the compatibility group was made by two factors of resin and irradiation angle,144 bond strength specimens were prepared and divided into 6 groups,dentin microtensile bond strengths were measured.Result:Two kinds of composite resin,three kinds of irradiation distance,three irradiation time curing depth of the comparison,the differences were statistically significant(P<0.001),all the interactions between the three factors were statistically significant(P<0.001).The bond strength between the two kinds of composite resin,the three light angle,the differences were statistically significant(P<0.001),the interaction between the two factors also had statistical significance (P<0.001).The bond strength of Solitaire 2 was greater than FiltekTMZ250,and the difference was statistically significant(F=104.62,P<0.01).Conclusion:The properties of different light curing composite resin for cure depths and bond strengths of dentin are different,and it should be combined with the factors such as irradiation distance, irradiation angle and irradiation time, so as to obtain good repair effect.关键词
