这篇研究的目的是为了呈现一种全新的动态导航技术以获得最小入路洞型预备,并评估它在上下磨牙中定位模拟高难钙化根管的3维(3D)准确性。

研究获得了3种相同标准设置的上下颌3D打印颌骨模型,包含84颗牙齿,并且在其解剖部位中设置了模拟钙化根管(N = 138 canals),置于牙科实习模型内。采用Navident dynamic navigation system (ClaroNav, Toronto, Ontario, Canada)由一名委员会认证的牙髓病科医师设计并通过高速钻头随机实施入路预备。采用叠加CBCT影像扫描数字化检测设计和实际髓腔预备之间2维(2D)和3D水平、垂直和角度差异。通过Analysis of covariance models评估牙齿类型和颌骨之间的联系和相互作用,以及设计和实际入路窝洞之间的根管口深度和差异。显著性水平设置为.05。

结果显示,距离根管口的平均2D偏差为0.9 mm,并且上颌牙偏差显著高于下颌牙(P < .05)。距离根管口的平均3D偏差为1.3 mm,它在上颌牙齿的边缘高于下颌牙齿(P ≥ .05)。平均3D角度偏差为1.7度,磨牙显著高于前磨牙(P < .05)。3D和2D的偏差不依赖于根管口的深度(P > .05)。平均钻磨时间为57.8秒,显著依赖于根管口的深度、牙齿类型和颌骨(P < .05)。

结论:这篇研究表明,动态3D导航技术配合高速钻头对于保存根管消失牙齿更多牙齿结构和准确定位根管具有很大潜力。
