Abstract
傳統全口活動義齒基底,大都採用硬式樹脂材料為基底,以提供較佳時間上
之穩固度。然少數牙床不理想之患者,較無法忍受及適應硬式基底之全口活動義
齒,因此相關學者建議此類患者改用軟式材料作為義齒基底,來增加患者舒適度
和配戴之成功率。然而軟式材料使用上,仍因部份問題有待克服,而沒有廣泛被
應用在全口義齒基底。因此,本研究為探討目前新型高強度高分子之活動義齒基
底材料之特性,係藉由掃描式電子顯微鏡、接觸角分析儀、拉伸與壓縮材料測試
機等設備進行成型溫度對新型高強度高分子牙材之機械性質影響;且依據ISO
10993-5規範進行細胞毒性之分析。分析結果顯示;經不同溫度成型之高分子基
底材具有相對高於市售活動義齒基底材料(最大拉伸力量32.2 kgf與最大壓縮力
量640.5kgf)之最大抗拉力量與最大壓縮力量約為125.6 kgf與1763.1 kgf。而細胞毒性測試中亦發現,經不同溫度成型之高分子基底材皆具有良好之生物相容性,故此新型高強度高分子可發展成一潛力之全口活動義齒基底材料。
