本实验用块状生物活性玻璃陶瓷复合钛网及部分脱矿异体骨（置于玻璃陶瓷的近牙龈端表面）修复犬下颌骨４～５ｃｍ长的节段性缺损（６例），并与单纯用块状生物活性玻璃陶瓷移植修复（６例）相比较。分别在术后１月、３月、６月对材料表面（牙龈端）及骨与材料的结合界面进行组织学观察。实验结果表明：部分脱矿异体骨有较强的诱导骨形成的能力，材料表面早期即可有自体骨覆盖，且骨可以长人材料孔隙内，长入的深度在观察期内随时间的延长而加深，而单纯陶瓷组６月时，材料表面仅有少量骨形成，骨向材料内生长不明显。界面骨长入材料孔隙的深度在观察期内亦随时间的延长而加深，且复合组优于单纯陶瓷组
In this study, segmental defects of 4 to 5 cm in length of the mandible (6 cases) were repaired with massive bioactive glass ceramic composite titanium mesh and part of demineralized allograft bone (placed near the surface of the gingival end of the glass ceramic) The use of massive bioactive glass ceramic graft repair (6 cases) compared. Histological observation was performed on the interface of the material (gingival end) and the interface of bone and material at January, March and June respectively. The experimental results show that part of demineralized allograft has a strong ability of inducing bone formation. Autologous bone can be covered early in the surface of the material, and the length of the bone in the long material can increase with the passage of time And deepened, while the simple ceramic group in June, the surface of the material only a small amount of bone formation, bone growth to the material is not obvious. The depth of the interface bones into the material pores deepened with the extension of time during the observation period, and the composite group was better than the pure ceramic group
