我们的目的是前瞻性评估萎缩颌骨内嵌体髂嵴移植物四个月的吸收率，并确定影响它们的因素。 24 名患者在下颌骨和上颌骨的 30 个部位使用髂嵴高嵌移植物重建牙槽嵴。在增强后（V-1）和四个月重塑后（V-2）直接在锥形束计算机断层扫描（CT）数据集上测量增强体积。统计分析可以识别受体部位、移植物体积和患者吸烟行为的潜在影响。平均（范围）初始覆盖移植物体积 (Vi) 为 2.82（0.66 至 6.41）ml。四个月后，测量的平均高嵌体移植物体积 (V2) 为 2.39（0.47 至 6.21）ml。重塑四个月后平均髂嵴覆盖移植物体积吸收为 0.43 (-0.15 - 1.78) ml (15%)。我们发现不同受体部位（上颌骨和下颌骨）之间的髂嵴覆盖移植物的吸收率没有显着差异，或者与髂嵴移植物的体积无关。吸烟者的吸收率往往较高，但并不显着 (p = 0.056)。这项研究的结果表明，据我们所知，迄今为止已发表的髂嵴高嵌体移植物具有最有利的吸收率。 (C) 2016 年英国口腔颌面外科医师协会。由爱思唯尔有限公司出版。保留所有权利。
Our aim was to assess the four months' resorption rates of onlay iliac crest grafts in atrophic jaws prospectively, and to identify factors that influence them. Twenty-four patients had reconstructions of the alveolar ridge with iliac crest onlay grafts at 30 sites on the mandibles and maxillas. The augmentation volumes were measured on cone-beam computed tomographic (CT) data-sets directly after augmentation (V-1), and after four months' remodelling (V-2). Statistical analysis allowed identification of potential influences from the recipient sites, volume of the graft, and the patients' smoking behaviour. The mean (range) initial onlay graft volume (Vi) was 2.82 (0.66 to 6.41) ml. After four months, the mean measured onlay graft volume (V2) was 2.39 (0.47 to 6.21) ml. Mean iliac crest onlay graft volume resorption after four months of remodelling was 0.43 (-0.15 - 1.78) ml (15%). We found no significant differences in the resorption rates of iliac crest onlay grafts between different recipient sites (maxilla and mandible) or in dependence on the volume of iliac crest grafts. Smokers tended to have a higher rate of resorption, but not significantly so (p = 0.056). The results of this study indicate the most favourable resorption rates for iliac crest onlay grafts that we know have seen published to date.
