Investigations were undertaken to evaluate nonresorbable, particulate ceramic hydroxylapatite (durapatite) for augmentation of deficient alveolar ridges. One hundred and fifteen augmentations in both jaws were reported for 110 patients over a 33-month postoperative period. Subjective and objective data show that the implant was successful for all classes of ridges augmented; height, bulk, contour, and ridge form generally improved, and soft tissue overlying the augmented ridges was firm and immobile. Impressions for dentures were usually obtained four to six weeks after surgery, and the dentures were more stable, retentive, and esthetically pleasing than the preoperative prostheses and required fewer relinings. Other than transiently altered sensations resulting from mental nerve manipulation during surgery, patients had few complications. No infection or bone resorption beneath the implant was observed throughout these studies. It was concluded that hydroxylapatite particles placed through a subperiosteal tunnel offer a highly successful method of ridge augmentation and eliminate the most serious problems associated with the use of autogenous or banked bone, namely, morbidity, risk, costliness, and poor results.
开展了相关研究，以评估不可吸收的颗粒状陶瓷羟基磷灰石（致密磷灰石）用于增高不足牙槽嵴的效果。在术后33个月的时间里，对110例患者上下颌共115处增高术进行了报告。主观和客观数据表明，对于所有增高的各类牙槽嵴，植入均获成功；高度、体积、外形及牙槽嵴形态总体上得到改善，增高牙槽嵴上方的软组织坚实且无移动。通常在术后四至六周取义齿印模，义齿比术前假体更稳定、固位性更好且美观，所需重衬更少。除手术期间因颏神经操作导致感觉短暂改变外，患者几乎没有并发症。在整个这些研究中，未观察到植入物下方有感染或骨吸收情况。得出的结论是，通过骨膜下隧道植入羟基磷灰石颗粒提供了一种非常成功的牙槽嵴增高方法，且消除了与使用自体骨或储存骨相关的最严重问题，即发病率、风险、成本高昂及效果不佳。
