BioDent,OsteoProbe®利用參考點壓痕量測技術(shù)檢測活體內(nèi)骨骼組織之機械性質(zhì)！
BioDent? 骨等組織參考點壓痕測試分析系統(tǒng)可以測量骨和其他組織的力學(xué)特性，具有離體測量和在體測量兩種模式，可以直接在活體動物上在體測試分析骨等組織等力學(xué)特性；能獲得以前無法獲得的臨床數(shù)據(jù)，如骨和其他組織的材料性質(zhì)，對骨等組織尤為適用。 OsteoProbe® RUO為便攜式在體/離體骨組織測量儀為BioDent? 骨等組織參考點壓痕測試分析系統(tǒng)手持版本
BioDent使用設(shè)計獨特的微探針在微米水平上對組織施壓。探針處于一個小套管內(nèi)部(圖2 A)，套管可在組織上或組織內(nèi)部建立參考點，然后便可測量軟、硬材料和生物材料的凹陷距離、相對剛度和能量耗散，從而**地檢測材料力學(xué)性質(zhì)(圖2 B)。在恒力工作模式下，BioDent測量探針相對于參考點移動的距離，作為在此壓力下材料發(fā)生的形變。在恒定距離工作模式（即將推出）下，BioDent測量使材料發(fā)生此種程度的形變時需要的力。
BioDent可臨床測量材料性質(zhì)作為健康或病變組織的指標(biāo)。這些組織通常由不同的軟硬組織在微米尺度上組合形成（圖3），BioDent可在微米和毫米尺度上進行測量，以用于不同的生物材料。
OsteoProbe® RUO是在體測量骨組織材料性質(zhì)的**儀器，是實驗室和臨床研究中測量骨質(zhì)量的有力工具。OsteoProbe® RUO是一種便攜式單手操作微壓痕儀，與測量骨密度的放射性方法（X射線、DXA和CT）具有不同的原理，它使用參考點壓痕技術(shù)來檢測材料對局部壓力的抵抗性。
OsteoProbe® RUO使用特別設(shè)計的探針來進行皮下測量，無須切開組織。探針刺空軟組織達到骨表面建立一個參考點，當(dāng)探針受力達到一個預(yù)先設(shè)定的閾值后會自動觸發(fā)更大的力進行測量。軟件會記錄下來凹陷深度和力之間的函數(shù)關(guān)系，然后用聚甲基丙烯酸甲酯作為參照材料進行校準(zhǔn)來獲得BMSi（材料強度指數(shù)）。
