The sinus lift with lateral approach is a regenerative technique nowadays considered predictable to increase the height of bone in the atrophic posterior maxilla. Knowledge of sinus anatomy and evaluation of risk factors are the basis of regenerative and rehabilitative surgical success. The positioning and size of the lateral antrostomy represent critical factors in the execution of regenerative surgery, due to the difficulty in transferring radiological information to the lateral wall of the maxillary sinus even for skilled surgeons. The knowhow of guided implant surgery in recent years is also finding use in planning and precisely delineating the lateral access to the maxillary sinus using CBCT imaging and dimensional reconstruction software, through the realization of surgical guides with 3D printing, as shown in the presented case.
经外侧入路的窦提升术是一种再生技术，目前被认为可预测性地增加后上颌骨萎缩区的骨高度。窦腔解剖知识和危险因素评估是再生和修复性外科成功的基础。尽管对于熟练的外科医生来说，将放射影像学信息转移到上颌窦外侧壁也具有一定难度，但外侧牙槽嵴切开术的定位和大小仍是再生手术执行过程中的关键因素。近年来，引导种植手术技术也可用于使用 CBCT 成像和尺寸重建软件来规划和精确描绘上颌窦的外侧通路，通过使用 3D 打印技术实现手术导板，如所介绍的病例中所示。
