摘要

摘要: 目的义齿基托材料的亲水性和力学特性都会对义齿基托的修复效果造成影响，本次主要研究添加不同量丝胶粉对义齿基托树脂表面亲水性及力学特性的影响。方法将不同粉末和单体组成4种组合，A组：D-300-甲基丙烯酸甲酯(MMA); B组：D-250ML-甲基丙烯酸异丁酯(iBMA); C组：D-100M-甲基丙烯酸异辛酯(EHMA)+甲基丙烯酸2-羟基乙酯(HEMA); D组：D-250E-EHMA+MMA。各组添加不同量丝胶粉(0%、1%、3%、5%)得到16种材料。测定材料浸泡0、60、120、240、300、360 d的表面接触角，计算抗折性能、弹性模量。结果 (1) 各组不同丝胶粉添加量样本的接触角、抗折强度、弹性模量的差异有统计学意义(均P < 0.05)。(2)各组无添加样本接触角高于添加3%丝胶粉样本(均P < 0.05)。各组添加3%丝胶粉样本浸泡180~360 d时间段的接触角呈降低趋势。C组浸泡360 d、添加3%丝胶粉样本的接触角最低(58.31±5.42)°。(3)未添加丝胶粉样本中，A组抗折强度高于其他3组(均P < 0.05)。A组和D组中添加3%丝胶粉样本浸泡360 d的抗折强度较高，为(122.31±9.73)MPa和(117.47±8.99)MPa。(4)B组中添加1%、3%、5%丝胶粉样本的弹性模量高于无添加样本(均P < 0.05)。A组添加5%丝胶粉、B组添加1%丝胶粉和D组添加3%丝胶粉样本的弹性模量较高。结论添加不同量丝胶粉可增加义齿基托表面的亲水性，但抗折强度及弹性模量也会受到一定影响。

Abstract: Objective The hydrophilic and mechanical properties of the denture base material will affect the repair effect of the denture base. This study mainly investigates the influence of adding different amounts of silk glue powder on the hydrophilic and mechanical properties of the denture base resin surface. Methods Powders and monomers were prepared into 4 combinations: D-300-MMA (Group A), D-250ML-iBMA (Group B), D-100M-EHMA+HEMA (Group C) and D-250E-EHMA+MMA (Group D). Each group was added with different amounts of sericin powder (0%, 1%, 3%, 5%) to obtain 16 kinds of materials. The surface contact angle of the material soaked for 0, 60, 120, 240, 300 and 360 d was measured, and flexural resistance and elastic modulus were calculated. Results (1) Statistically significant differences were found in the contact angle, flexural strength and elastic modulus of samples in each group added with different amounts of sericin powder (P < 0.05). (2) The contact angle of the samples without 3% sericin powder in each group was higher than that of the samples added with 3% sericin powder (P < 0.05). The contact angle of the samples in each group added with 3% sericin powder immersed for 180-360 d showed a decreasing trend. The contact angle of group C soaked for 360 d and added with 3% sericin powder was the lowest (58.31°±5.42°). (3) Among the samples without sericin powder, the flexural strength of group A was higher than that of the three other groups (P < 0.05). The flexural strengths of the samples in groups A and D added with 3% sericin powder soaked for 360 days were higher, with values of (122.31±9.73) and (117.47±8.99) MPa, respectively. (4) The elastic modulus of the samples added with 1%, 3% and 5% sericin powder in group B was higher than that of the samples without the powder (P < 0.05). The samples with 5% sericin powder added in group A, 1% sericin powder in group B and 3% sericin powder in group D had higher elastic moduli. Conclusion Adding different amounts of sericin powder can increase the hydrophilicity of the denture base surface, however, the flexural strength and elastic modulus will also be affected to a certain extent.
