部分或全部失牙患者严重上颌牙槽嵴萎缩和(或)上颌窦腔增大的处理一直是口腔外科医生和修复科医生的难题。常规手术改善义齿固位有限,欲采用骨内种植体则因容纳种植体的骨量不足而无法进行。作者采用一种新的方法,在植入螺纹型骨内种植体的同时将取自下颌骨的自体骨移值固定于上颌骨,达到再造严重萎缩的上颌骨的目的。 Treatment of some or all of the missing patients with severe maxillary alveolar ridge atrophy and / or maxillary sinus enlargement has been a challenge for oral surgeons and rehabilitative surgeons. Conventional surgery to improve the retention of dentures is limited, the use of intraosseous implants due to insufficient bone volume to accommodate the implants and can not be carried out. The authors adopted a new method to fix the maxillary bone to the maxillary bone in order to reconstruct the severely atrophied maxillary bone while implanting the screwed bone implant while fixing the autologous bone graft from the mandible.
