摘要
目的:观察无机填料的含量对纳米羟基磷灰石(n-HA)复合树脂双键转化率的影响.方法:将经过硅烷偶联剂KH-570表面处理后的n-HA作为无机填料与配制好的光固化树脂基体共混,制备成复合树脂材料,并根据n-HA在复合材料中所占的比例将其分为A(45 wt％)、B(55 wt％)、C(65 wt％)、D(75 wt％)4组,同时取卡瑞斯玛光固化复合树脂作为对照(E组).然后将5组复合树脂各制作5个试件,并分别测定各组试件的红外吸收光谱(IR),同时计算其双键转化率.结果:复合树脂材料中n-HA所占比例对其双键转化率具有一定影响,所占比例为45 wt％、55 wt％及75 wt％时,双键转化率均低于对照组及65 wt％组(P＜0.05);65 wt％组与对照组双键转化率分别为(48.56±1.54)％和(45.72±0.91)％(P＞0.05).结论:纳米羟基磷灰石填料的含量可影响复合树脂的双键转化率,当n-HA含量为65 wt％时,其双键转化率最高.
Abstract
AIM:To study the effects of inorganic filler content on the double bonds conversion of nano hydrxyapatite (n-HA) composite resin.METHODS:The composite materials were composed of a visible light-curing monomer mixture as a matrix and n-HA as an inorganic filler.The surface of the n-HA particles was modified by a silane coupling agent KH-570.The quality proportion of n-HA in the composite materials was 45 wt％ (group A),55 wt％ (group B),65 wt％ (group C) and 75 wt％ (group D) respectively (n =5),CHARISMA was served as the control group (E).The infra-red (IR) spectra of composite resins was determined and the degree of double bonds conversion was calculated.Data were subjected to variance analysis.RESULTS:The double bonds conversion rate of group A,B and D was lower than that of group C and E (P ＜ 0.05).The double bonds conversion rate of group C and E was (48.56 ± 1.54) ％ and (45.72 ± 0.91) ％ respectively (P ＞ 0.05).CONCLUSION:The content of inorganic fillers has a certain influence on the double bonds conversion of n-HA composite resin,n-HA at 65 wt％ may produce the highest double bonds conversion of n-HA composite resin.
