【摘要】：目的:通过对Constic自粘接流动树脂、FiltekTM Supreme Ultra树脂及Spectrum TPH3树脂三种材料的拉伸强度、抗压强度、挠曲强度以及剪切粘接强度进行比较,为Constic树脂的临床应用提供理论依据。方法:首先制备Constic自粘接流动树脂(A组)、FiltekTM Supreme Ultra树脂(B组)及Spectrum TPH3树脂(C组)试件,使用电子式万能试验机测试三组材料的拉伸强度、抗压强度以及挠曲强度值。其次制备Constic自粘接流动树脂(A组)、Constic自粘接流动树脂加粘接剂(B组)、FiltekTM Supreme Ultra树脂(C组)、Spectrum TPH3树脂(D组)试件,使用电子式万能试验机测试四组的剪切粘接强度值,在显微镜下观察试件的断裂面破坏形式。对数据进行统计学分析,统计描述使用(SX?),组间比较使用方差分析,进一步两两比较使用多个样本均数间多重比较的SNK(Student-Newman-Keuls)法检验,检验水准为α=0.05(双侧),P0.05有统计学意义。结果:Constic树脂(A组)、FiltekTM Supreme Ultra树脂(B组)及Spectrum TPH3树脂(C组)三组的拉伸强度值分别为31.10±8.35MPa,35.10±6.65MPa,30.00±7.08MPa,A组的强度值与B组、C组相近,三组间无统计学差异(P0.05)。抗压强度,A、B、C组结果分别为287.53±22.99MPa,358.85±32.67MPa,355.72±43.18MPa,A组的抗压强度值显著低于B组和C组,与B、C两组间有统计学差异(P0.05)。挠曲强度,A、B、C组结果分别为101.09±18.18MPa,115.05±19.08MPa,109.94±28.23MPa,A、B、C三组间无统计学差异(P0.05)。剪切粘接强度,Constic树脂(A组),Constic树脂加粘接剂(B组),FiltekTM Supreme Ultra树脂(C组),Spectrum TPH3树脂(D组)的强度值分别为19.48±1.58MPa,24.22±3.00MPa,20.42±3.09MPa,17.80±2.07MPa,A、C及D组间无统计学差异(P0.05),B组剪切粘接强度值显著大于其他三组,B组与A、C、D组间有统计学差异(P0.05)。在显微镜下,观察到的试件断裂面的破坏形式主要为粘接界面断裂,少部分为混合断裂。结论:本研究结果显示Constic自粘接流动树脂的拉伸强度、挠曲强度、剪切粘接强度值与其它两种在临床中已广泛应用的树脂相接近。虽然Constic自粘接流动树脂的抗压强度略低于其他两种树脂,但仍能满足口腔充填材料的要求,因此可以在临床中推广应用。
[Abstract]:Objective: to compare the tensile strength, compressive strength, flexural strength and shear bonding strength of Constic self-adhesive flowing resin FiltekTM Supreme Ultra resin and Spectrum TPH3 resin in order to provide theoretical basis for clinical application of Constic resin. Methods: the Constic self-adhesive flow resin (group A) and the Spectrum TPH3 resin (group C) were prepared. The tensile strength, compressive strength and flexural strength of the three groups were tested by electronic universal testing machine. Secondly, the Constic self-adhesive flow resin (group A) was prepared, and the shear bonding strength of the four groups was tested by using electronic universal testing machine, which was made of Constic self-adhesive flow resin plus adhesive agent (group B) and FiltekTM Supreme Ultra resin (group C) and TPH3 resin (group D). The failure form of fracture surface was observed under microscope. The data were analyzed statistically, SX? was used, ANOVA was used in the comparison between groups, and SNK (Student-Newman-Keuls) method was used to test the multiple comparisons between the mean numbers of multiple samples. The test level was 伪 0. 05 (both sides) (P0.05) with statistical significance. Results the tensile strength of group A and group B were 31.10 卤8.35 MPA and 35.10 卤6.65 MPA / min, respectively. The tensile strength of group A was similar to that of group B (P 0.05). The tensile strength of group A was similar to that of group B (group A). There was no statistical difference among the three groups (P0.05). The tensile strength of group A was significantly higher than that of group B (P 0.05). The tensile strength of group A was similar to that of group B (30.00 卤7.08MPA) (P 0.05). The compressive strength of group A was significantly lower than that of group B and group C (287.53 卤22.99 MPA, 358.85 卤32.67 MPA, 355.72 卤43.18 MPA, P0.05). There was no statistical difference among the three groups (101.09 卤18.18 MPA, 115.05 卤19.08 MPA, 109.94 卤28.23 MPA, P 0.05). The shear strength of Supreme Ultra resin (group C) was 19.48 卤1.58 MPA (24.22 卤3.00 MPA) and 20.42 卤3.09 MPA (17.80 卤2.07 MPa AHG) respectively. There was no statistical difference between group A and D (P0.05). The shear bond strength of group B was significantly higher than that of group B (P 0.05). The shear strength of group B was significantly higher than that of group B (P 0.05), and that of group D was significantly higher than that of group B (group D). (P0.05) the shear bond strength of group B was significantly higher than that of group B (P 0.05), and that of group B was significantly higher than that of group B (P 0.05). There was a significant difference between the two groups (P0.05). Under the microscope, the fracture surface of the specimen is mainly composed of bonding interface fracture, and a small part of the fracture surface is mixed fracture. Conclusion: the results show that the tensile strength, flexural strength and shear bonding strength of Constic self-adhesive flow resin are close to those of the other two kinds of resins which have been widely used in clinic. Although the compressive strength of Constic self-adhesive flow resin is slightly lower than that of the other two kinds of resin, it can still meet the requirements of oral filling material, so it can be popularized and applied in clinic.
