From six months to four years after alveolar ridge augmentation was performed, the vertical ridge heights of 74 Class III and Class IV alveolar ridge deficiency patients, who had undergone augmentation with hydroxylapatite with or without autogenous cancellous bone, were measured using panoramic radiographs adjusted for magnification errors. No statistically significant decreases in vertical ridge heights were seen when only hydroxylapatite was used, nor were there significant differences between the two types of hydroxylapatite particles used. Unlike other bone onlay procedures, the use of autogenous bone and HA together did not result in significant decreases in vertical ridge height.
在牙槽嵴增高术后6个月至4年期间，对74例III类和IV类牙槽嵴缺损患者进行了垂直嵴高度测量，这些患者接受了羟基磷灰石联合或不联合自体松质骨的增高术，测量采用了针对放大误差进行调整的全景X线片。仅使用羟基磷灰石时，垂直嵴高度未见统计学显著降低，所使用的两种类型的羟基磷灰石颗粒之间也无显著差异。与其他骨覆盖手术不同，自体骨和羟基磷灰石联合使用并未导致垂直嵴高度显著降低。
