dc.description.abstract | 相較於傳統填料,奈米粒子能夠賦予複合材料更高的機械強度,更高的透光性,而填補樹脂必須同時具備美觀與強度的特性,因此將奈米粒子應用於牙科填補複合樹脂的製作成為了一個新趨勢。 本研究 以Hydroxypivalaldehyde modified trimethylolpropane diacrylate (HTPDA)、Tricycylodecanedimethanol diacrylate (TCDDA)以及Ethoxylated(2) Bisphenol A dimethacryalate (EO(2)BDMA)三種壓克力的混合物做為基質,以矽烷偶合劑改質之兩種不同粒徑的二氧化矽奈米粒子作為填料,來製備可見光聚合之有機無機複合材料。藉由熱分析,吸水性測試,以及機械性質測試,與五種市售牙科填補複合樹脂進行比較,評估其作為牙科填補複合樹脂之可行性。 由測試結果發現,本材料與其他市售材料相比具有最低之熱膨脹係數,最低之吸水性,細胞毒性也與生物相容性較高之市售材料相近的,微硬度值為87.06Hv高於大多數的市售材料,聚合收縮度也在可接受的範圍,微硬度值在照光聚合四十秒後可達穩定,符合牙醫師臨床操作上的要求,因此本材料只要能夠再提高直徑拉伸強度,便可成為良好之牙科填補複合材料。 | zh_TW |
dc.description.abstract | Compare to traditional filler, nanoparticles give composite materials higher mechanical properties and transparency. On the other hand, dental restorative resins should fulfill the requirements of aesthetic and strength, So the use of nanoparticles in formulation of dental restorative composite resin has been a new trend. In this research, photocurable organic-inorganic hybrid was made of two different sizes of nanoparticles treated by silane coupling agent, and an acrylate matrix, which consisted of hydroxypivalaldehyde modified trimethylolpropane diacrylate (HTPDA), tricycylodecane dimethanol diacrylate (TCDDA), and ethoxylated(2) bisphenol A dimethacryalate (EO(2)BDMA). The developed nanocomposite was compared with five commercial material using thermal analysis, water absorption test, and mechanical test to evaluate the feasibility for application on dental restoration. As compared with commercial materials, the best formulation (F-80) had the lowest coefficient of thermal expansion, the lowest water absorption, comparable cytotoxicity with better bio-compatible commercial resins, high microhardness of 87.06Hv(higher than most commercial resins), and acceptable polymerization shrinkage . The value of microhardness became stable after light curing for 40 seconds. This met the requirement of dental clinic. If the diametal tensile strength can be improved, this developed material will be very suitable for restorative material in dental clinic. | en |
