上颌后牙区萎缩后牙槽骨高度小于5 mm时，传统的治疗方法是采用侧窗技术和延迟种植体植入进行上颌窦提升。本文介绍了一种经牙槽骨窗入路（TWA），用于替换萎缩后牙槽骨高度（RBH）为1 ~ 2 mm的缺失第一磨牙。进行了经筛窦提升和延迟种植体植入。上颌窦提升手术后，锥形束计算机断层扫描图像显示上颌窦假性囊肿消失。1年随访显示植入成功，Periotest值为-4.8。这种方法减少了患者的不适。RBH为1 - 2 mm的TWA是上颌窦提升的微创方法。
Sinus augmentation with a lateral window technique and delayed implant placement are the traditional treatment schedules when the residual alveolar bone height in atrophic posterior maxilla is less than 5 mm. This article presents a transcrestal window approach (TWA) to replace a missing first molar in an atrophic posterior maxillary ridge with 1 to 2 mm of residual bone height (RBH). Transcrestal sinus augmentation and delayed implant placement were performed. The antral pseudocyst that was located in the nasal wall of the maxillary sinus disappeared in the cone-beam computer tomography images taken after sinus elevation surgery. The 1-year follow-up visit showed that the implant was successful and the Periotest value was -4.8. This approach reduces discomfort to the patient. The TWA with an RBH of 1 to 2 mm is a minimally invasive method for maxillary sinus augmentation.
