Treatment of severe maxillary atrophy with implants has achieved important successes in recent years. The limit of implant insertion is related to inadequate bone quantity (i.e. height and width). Alveolar bone grafting, sinus lifting and major grafting via Le Fort I osteotomy have used in the past to restore bone volume prior of implant insertion. However successes do not always occur and a second stage surgery is necessary in most cases. Immediate loading cannot be performed in all grafted bone. In recent years a new treatment approach has been proposed by using zygomatic implants. This new technique can provide a better stability to the prosthesis and less morbidity for patient. Here a cases series of eighteen patients rehabilitated with zygomatic together with standard implants and immediate loading is reported.
近年来，采用种植体治疗严重上颌骨萎缩取得了重要进展。种植体植入的限制与骨量不足（即高度和宽度）有关。过去曾采用牙槽骨移植、上颌窦提升术以及通过Le Fort I截骨术进行大型植骨术，以便在植入种植体之前恢复骨量。然而，并非总能成功，在大多数情况下需要进行二期手术。并非所有植骨部位都能进行即刻负重。近年来，有人提出了一种使用颧骨种植体的新治疗方法。这种新技术可为假体提供更好的稳定性，且对患者而言发病率更低。本文报告了一组18例采用颧骨种植体联合标准种植体并进行即刻负重修复的病例。
