背景/目的:牙周組織周圍的牙科樹脂黏固劑殘留是植體周圍炎的原因之一。嚴重病例可能導致植體鬆動或脫落。因此,本研究旨在對礦物三氧化物聚集體(MTA)進行改性,使其成為一種抗發炎的牙科植體冠黏固劑(ICC)。
材料與方法:本研究評估了去離子水溶液(Daq)、羥基磷灰石溶液(Haq)和氯化鈣溶液(Caq)對ICC凝固時間、抗壓強度、黏結強度和生物相容性的影響。以單因子變異數分析(ANOVA)檢定各實驗組間的差異( P < 0.05)。
結果:表面微觀結構分析表明,添加Haq和Caq有助於ICC顆粒間的結合。表面元素分析表明,添加Haq增加了Ca離子含量。凝固時間結果表明,與Daq相比,Caq和Haq分別使最終凝固時間縮短了46.5%和34.7%( P < 0.05)。 Caq的抗壓強度分別比Daq和Haq高35.1%和13.4%( P < 0.05)。三種ICC組的黏接強度結果表明,樹脂黏接劑的效果相同( P > 0.05)。生物相容性和清除活性測試表明,ICC優於樹脂黏接劑。
結論: ICC與Caq合併使用可縮短凝固時間、提高抗壓強度、增強生物相容性並降低發炎發生的可能性。因此,ICC與Caq聯合使用可作為牙科樹脂黏固劑的替代方案。
