A surgical procedure for the rehabilitation of severely resorbed maxillae is described. Twenty-five patients, made up of a development group of 5 and a routine group of 20, were treated with Le Fort I osteotomy using interpositional bone grafts from the iliac crest and, in a second stage, titanium implants. Altogether, 181 Brånemark implants were placed, and the patients were followed for up to 5 years. The implant survival rate for the development group was 60.0% after 5 years. Life table analysis for the routine group showed a 5-year survival rate of 85.6%. Twenty-two patients received fixed prostheses and 2 received overdentures. One patient lost all implants and was rehabilitated with a prong denture.
本文描述了一种用于严重吸收上颌骨修复的外科手术方法。25例患者分为5例的实验组和20例的常规组，采用Le Fort I截骨术，术中植入取自髂嵴的骨块，二期植入钛种植体。共植入181枚Brånemark种植体，对患者进行了长达5年的随访。实验组5年后种植体存留率为60.0%。常规组的生命表分析显示5年存留率为85.6%。22例患者接受了固定义齿修复，2例患者接受了覆盖义齿修复。1例患者所有种植体均脱落，采用叉形义齿进行修复。
