Abstract： 目的探讨颧种植体在上颌后牙区严重吸收和上颌骨缺损患者中的植入方法及其辅助定位.方法 5例患者共成功植入8枚颧种植体.所有患者术前颧骨、上颌骨均行三维CT重建,采用计算机辅助设计、辅助制作(CAD-CAM)技术制作1:1快速原模型,在三维CT和模型上测量颧骨和上颌骨的相关参数.按颧种植体植入的外科程序操作.结果 8枚颧种植体和11枚常规牙种植体植入方向和位置理想,骨结合良好;颧种植体的长度40～50 mm;应用解剖学模型和外科模板使种植体定位精确.结论颧种植体植入是上颌后牙区严重吸收和上颌骨缺损患者咀嚼功能重建的一种可行方法,三维CT、CAD-CAM技术的应用使颧种植体的植入更为精确,患者颧骨和上颌骨相关参数的测量有助于术前计划、适应证选择和术中颧种植体的植入.
