J Endod:评估不同技术充填三维打印树脂牙齿的模拟C型根管效果

2017-08-04 MedSci MedSci原创

这篇研究的目的是通过三维(3D)打印技术模拟C1型根管解剖形态,比较不同根管充填方法充填C型根管的效果。

这篇研究的目的是通过三维(3D)打印技术模拟C1型根管解剖形态,比较不同根管充填方法充填C型根管的效果。研究通过锥束CT(CBCT)成像技术扫描下颌磨牙,并从CBCT成像结果中选取一颗具有C1型根管形态的下颌磨牙。使用ProTaper通用旋转器械(Dentsply Maillefer, Ballaigues, Switzerland)和手用锉进行根管成形。根管成形后,通过micro-CT成像技术扫描牙齿,并使用3D打印技术复制出80颗牙齿副本。将牙齿副本分为4组(n = 20),并按照下列技术分别充填:核载体系统(GuttaCore [GC]; Dentsply Tulsa Dental Specialties, Tulsa, OK),连续波充填系统(Elements Free [CW]; Kerr/SybronEndo, Orange, CA),冷侧压技术(CLC),或者注射冷充填(GuttaFlow Bioseal [GFB]; Coltène/Whaledent AG, Altstatten, Switzerland)。所有样本距离根尖2, 4, 6, 8和10 mm处水平切开。
