Abstract
目前臨床應用檢測植體與齒槽骨間之癒合程度與穩固程度的共振頻率原理有以諧振響應法HRM的Osstell? (Integration Diagnostics, Sweden)系統以及以激振衝擊法IFM的Implomates? (BioTech One, Inc., Taipei, Taiwan)系統兩者。但是尚未有關於兩者量測結果之間差異性探討以及相關性的研究。本研究即以激振衝擊法Implomates?系統與諧振響應法Osstell?系統植體穩固度監測儀器進行一系列的試驗。體外的模擬試驗在改變各種可能影響植體穩固度的參數條件下,探討此兩種系統儀器其所得到結果的操作差異與相關性。此外本研究以動物模型進行牙科植體治療,並且於12週的骨癒合期間進行量測,同時以放射線X光進行骨-植體邊界的觀察。另外收集臨床上接受牙科植體(3i,Inc. FL, USA)治療的患者臨床診斷資料,在其植入牙科植體時,以及之後的第2、4、8、12週接受IFM量測植體穩固度的量值進行分析。在體外實驗結果發現,隨著穩固度增加,兩系統量測到的穩固度數值均同樣增加,結果也存在一線性關係趨勢以及高度正相關(y = 0.31x -11.62,R = 0.98,p<0.05)。以動物模型進行兩者線性轉換方程式的校正,我們可以訂出兩系統量測值ISQ與kHz轉換方程式為kHz = 0.3 ISQ - 8.0。而分析臨床植體穩固度資訊,可以依照植體初始穩固度區分為三種癒合型態:RF值大於10.0kHz則可以接受立即負載,RF值介於4.0至10.0kHz之間者則需要等待骨整合完成,低於4.0kHz者建議需要更保守的治療。此結果表現出IFM法的確可以用來表現植體穩固度,而其量測數值與HRM之ISQ值間具有相關性及可轉換性。而且依照初始穩固度的量測可以提供臨床醫師進行後續治療的資訊,值得再進一步探討研究穩固度量值與植體骨整合的變化。
