Artifacts from metal restorations can make it challenging or impossible to accurately orient a digital dental cast to cone beam computed tomography (CBCT) scan data for virtual implant planning. A dual scan technique is described that uses an alginate impression with fiducial markers in a stock tray to create a digital dental cast that is precisely oriented to the scan in the same patient coordinate system for surgical guide design.

为虚拟种植体规划创建精确牙齿表面的双扫描方法:一种牙科技术

来自金属修复体的伪影使得将数字牙科模型准确定位到锥形束计算机断层扫描 (CBCT) 扫描数据以进行虚拟种植体规划变得具有挑战性或不可能。描述了一种双扫描技术,该技术使用带有基准标记的藻酸盐印模在托盘中创建数字牙科模型,该模型在同一患者坐标系中精确定向到用于手术导板设计的扫描。
