These investigations were undertaken to evaluate durapatite, a particulate, ceramic, nonresorbable bone-grafting material for augmentation of deficient alveolar ridges. A total of 207 augmentations were reported among 198 patients over 24 months. Subjective and objective data showed that durapatite alone 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 usually began 4 to 6 weeks after surgery and these dentures remained stable, retentive, and esthetically pleasing throughout the study. Other than transiently altered sensations resulting from mental nerve manipulation during surgery, no other important procedural complications were noted. No infection or bone resorption beneath the implant was observed throughout these studies. Durapatite used in an outpatient setting provides a less costly and more permanent method for alveolar ridge augmentation than do augmentation procedures using autogenous or banked bone.
开展这些研究是为了评估磷酸三钙，一种颗粒状、陶瓷质、不可吸收的骨移植材料，用于增高不足的牙槽嵴。在24个月内，198名患者共进行了207次增高手术。主观和客观数据表明，单独使用磷酸三钙对所有增高的各类牙槽嵴均取得成功；高度、体积、外形和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性。假牙印模通常在术后4至6周开始制取，在整个研究过程中，这些假牙保持稳定、固位良好且美观。除了手术过程中因颏神经操作导致的短暂感觉改变外，未发现其他重要的手术并发症。在这些研究中，未观察到种植体下方有感染或骨吸收情况。在门诊环境中使用磷酸三钙比使用自体骨或储存骨的增高手术提供了一种成本更低且更持久的牙槽嵴增高方法。
