研究目的是从组织学及血液学来研究多孔磷酸三钙陶瓷作为一种加大牙槽嵴的生物材料。作者用十条成年的杂种狗进行实验,在戊巴比妥钠麻醉下,先拔除下颌右侧所有后牙,并作了牙槽嵴修整。在两个月伤口愈合期后,作外科手术形成骨膜下通道,用多孔的磷酸三钙陶瓷加大牙槽嵴,陶瓷块大小约15×5×5mm,材料为多孔性的,其中孔占50%,每孔直径为400—500μm。在7、
The aim of the study was to study porous tricalcium phosphate ceramics as a biomaterial augmented by alveolar ridges from histology and hematology. The author experimented with ten adult mongrel dogs, and under anesthesia with sodium pentobarbital, all the posterior teeth on the right side of the mandible were removed and the alveolar crest trimmed. After two months of wound healing, the subperiosteal channel was surgically created and the alveolar ridge was expanded with porous tricalcium phosphate. The size of the ceramic block was about 15 × 5 × 5 mm and the material was porous with pores accounting for 50% , Each hole diameter 400-500μm. At 7,
