中文摘要 | 背景: 此實驗旨研究7種不同的黏合劑應用於牙科植體支持性牙套其固定力強度之評估與比較。 方法:56個鑄造好的牙套由7組不同的黏合劑來黏於56根植體支臺牙柱上。7組不同的黏合劑其中包括磷酸鋅黏合劑、樹脂黏合劑、樹脂加強型玻璃離子體黏合劑、聚羖酸鹽黏合劑、氧化鋅丁香油酚基底臨時性黏合劑、及丙烯酸脂臨時性黏合劑等。在應用咬合模擬機及溫度轉換機來模仿口腔環境及溫度後再測試黏合劑固位力之強度。One-way ANOVA 及Duncan’s Multiple Range Analysis用來評估與比較各黏合劑之固位力。 結果:每一組黏合劑固位力強度的平均值及標準差分別為:磷酸鋅黏合劑(Zinc phosphate):1.225 MPa (0.229);樹脂加強型玻璃離子體黏合劑(Advance);1.205 MPa (0.197);樹脂黏合劑(All Bond 2):1.752 MPa (0.211);樹脂黏合劑(Panavia F):1.679 MPa (0.176);聚羖酸鹽黏合劑(Durelon):0.535 MPa (0.161);氧化鋅丁香油酚基底臨時性黏合劑(Temp Bond):0.274 MPa (0.079);和丙烯酸脂臨時性黏合劑(ImProv):0.319 MPa (0.107)。 結論:樹脂黏合劑相較於其他具有最強的固位力而永久性黏合劑的固位力都比臨時性黏合劑要強。氧化鋅丁香油酚基底臨時性黏合劑具有最弱的固位力,即使它與丙烯酸脂臨時性黏合劑在統計沒有顯著性的差異。 |
英文摘要 | Background: This study was designed to evaluate the retentive strength of 7 different luting agents on cement-retained implant abutment/analog assemblies. Methods: Fifty-six Steri-Oss implant abutment/analog assemblies and cast superstructures were randomly divided into 7 groups: definitive cements included zinc phosphate cement, Advance, All-Bond 2, Panavia F, and Durelon, while provisional cements included Temp Bond and Improv. After the superstructures were cemented onto the implant abutments, the specimens were subjected to 100,000 cycles on a chewing machine (75N) and 1000 cycles on a thermo-cycling machine (0~55℃). A universal testing machine was used to test the cement failure load values for each specimen. One-way ANOVA and Duncan’s multiple-range analysis were used to determine the effects of luting agents on cement failure load values. Results: The following values for the mean and standard deviation of cement failure loads for each group were obtained: zinc phosphate, 1.225±0.229Mpa; Advance, 1.205±0.197Mpa; All Bond 2, 1.752±0.211Mpa; Panavia F, 1.679±0.176Mpa; Durelon, 0.535±0.161Mpa; Temp Bond, 0.274±0.079Mpa; and ImProv, 0.319±0.107Mpa. Conclusions: There were significant differences in cement failure loads among the various cements tested. Values significantly differed among 4 groups consisting of All-Bond 2 and Panavia F resin cements, zinc phosphate cement and Advance hybrid ionomer cement, Durelon carboxylate cement, and ImProv and Temp Bond provisional cements (p<0.0001). All-Bond 2 and Panavia F resin cements had statistically significantly higher values for cement failure loads compared to the other 5 types of cement. |
