Zygomatic implants are indicated for the rehabilitation of the severely atrophic maxilla. Similar to standard implant placement, gaining an optimal position of the zygomatic implants is essential for a predictable prosthetic-driven treatment outcome. Stereolithographic templates, either bone-supported or mucosa-supported, have been used to install zygomatic implants in the planned position based on computer-assisted planning. However, there is no effective mechanism to physically control the drilling trajectory for the zygomatic implants. Therefore, deviation between the actual and planned implant position is inevitable. A novel device designed to increase the precision of the guided surgical placement of zygomatic implants that guides the osteotomy from the entry point to the exit point, allowing optimal positioning, is presented herein.
颧骨种植体适用于严重萎缩上颌骨的修复。与标准种植体植入类似,获得颧骨种植体的最佳位置对于可预测的修复驱动治疗结果至关重要。基于计算机辅助规划,骨支持或黏膜支持的立体光刻模板已被用于将颧骨种植体安装在计划位置。然而,对于颧骨种植体,没有有效的机制来物理控制钻孔轨迹。因此,种植体实际位置与计划位置之间的偏差是不可避免的。本文介绍了一种新型装置,旨在提高颧骨种植体引导手术植入的精度,该装置可引导截骨术从入口点到出口点,实现最佳定位。
