After periods of observation from 3 to 36 months, biopsies were obtained from 22 patients in whom porous block and particulate hydroxylapatite ceramic (Interpore 200) had been used for augmentation procedures and in two patients in whom nonporous particulate hydroxylapatite (Calcitite) had been used. Histologic examination of serial sections of decalcified specimens revealed vital bone formation in relation to the blocks, whereas the particulate was encapsulated in fibrous tissue. The differences in biological behavior are discussed.
经过3至36个月的观察期后，从22例使用多孔块状和颗粒状羟基磷灰石陶瓷（Interpore 200）进行增强手术的患者以及2例使用无孔颗粒状羟基磷灰石（Calcitite）的患者身上获取了活检样本。对脱钙标本连续切片的组织学检查显示，与块状物相关的有活性骨形成，而颗粒则被包裹在纤维组织中。讨论了生物学行为的差异。
