3D打印磷酸三鈣TCP：德國INNOTERE生物材料應(yīng)用發(fā)表文獻(xiàn)
閱讀：1501 發(fā)布時間：2020-4-30INNOTERE Paste-CPC旨在填補(bǔ)創(chuàng)傷，重建或矯正干預(yù)后未感染的骨缺損。它是世界上di一種可注射的磷酸鈣基骨水泥糊劑，可作為即用型植入材料提供。一項(xiàng)新穎的，受專li保護(hù)的技術(shù)取代了對詳盡，耗時的術(shù)中骨替代水泥的制備，混合和轉(zhuǎn)移的需求。INNOTERE Paste-CPC可以直接使用，可以直接從注射器中使用，也可以通過使用套管將其粘貼到骨骼中。由于INNOTERE Paste-CPC僅在與水性液體接觸后才凝固，而不是在注射器中凝固，因此外科醫(yī)生在施工過程中沒有時間限制。自2015年初以來，INNOTERE Paste-CPC即可在歐盟用于臨床應(yīng)用。

INNOTERE 3D支架是一種合成的，多孔的，生物相容的且具有生物可吸收性的骨替代材料，用于填充或重建不承重的骨缺損或用于填充骨缺損，這些骨缺損已通過適當(dāng)?shù)姆绞竭M(jìn)行了充分穩(wěn)定。與傳統(tǒng)的預(yù)制骨替代品相比，INNOTERE 3D支架的特點(diǎn)是：
互連孔隙
使用全合成原材料的骨狀礦物相
可通過骨骼重塑過程吸收
INNOTERE 3D支架的創(chuàng)新功能來自使用INNOTERE創(chuàng)新的磷酸鈣骨水泥漿的新3D打印技術(shù)。該方法允許精確地調(diào)節(jié)所得支架的互連孔系統(tǒng)的孔隙率。所用的磷酸鈣糊劑在印刷過程之后通過特定的固化程序進(jìn)行固化，無需任何燒結(jié)步驟。這樣可以避免晶體生長，并導(dǎo)致支架主要由天然骨骼的礦相微晶羥基磷灰石組成。
INNOTERE 3D支架的特定應(yīng)用領(lǐng)域是：
干defect端骨折，例如脛骨，radius骨和肱骨骨折
良性腫瘤和囊腫切除后的骨缺損
口腔頜面外科的骨缺損
填充脊髓籠
