摘　　要：目的:比较β-磷酸三钙(β-tricalcium phosphat e,β-TCP)、珊瑚转化型羟基磷灰石生物陶瓷(cor al-hydr oxyapatite,CHA)两种人工骨材料在引导骨再生中成骨质量的差别,为临床应用提供指导。方法:拔除Begeal犬的下颌双测第二三四前磨牙,并植入种植体,在种植体颈部颊侧植被缺损,并以不同人工骨材料修复。结果:种植体均未脱落,缺损区粘膜愈合良好。A组:1、4个月时新骨生成率分别为23.00%±0.82%、58.00%±1.83%,种植体颈缘到颊侧骨缺损底部的距离为1.05±0.13mm、1.09±0.10mm。B组:1、4个月时的新骨生成率分别为23.75%±0.96%、57.75%±1.89%,种植体颈缘到颊侧骨缺损底部的距离分别为1.09±0.10mm、1.13±0.10mm。C组:1个月和4个月时的新骨生成率分别为4.25%±0.96%、16.50%±1.91%,种植体颈缘到颊侧骨缺损底部的距离分别为4.38±0.17mm、3.75±0.13mm。结论:CHA及β-TCP都具有良好的骨引导作用,可用于即刻牙种植骨缺损的修复。Objective: To observe the different effects on the quantity of new generated bone between β-TCP and CHA under the role of ADM diomembrane in alveolar augmentation operation of immediately implant in a dog model.Methods: Plant Branmark implants into the mandible immediately after pulling out premolar teeth,and bone defects of 3mm×4mm×5mm were prepared in the cheek side of alveolar bone.Results: None implant failed,defect decayed area mucous membranes accrete well,and no soft tissue splits.The generation rate of involucrum in 1 month and 4 months: Group A: 23.00%±0.82%,58.00%±1.83%.Group B: 23.75%±0.96%,57.75%±1.89%.Group C: 4.25%±0.96%、16.50%±1.91%.The distance from neck margin of the implant to the defect level: Group A: 1.05±0.13mm,1.09±0.10mm;Group B: 1.09±0.10mm,1.13±0.10mm;Group C: 4.38±0.17mm、3.75±0.13mm.Conclusion: ADM biomembrane and β-TCP both can aim osteanagenesis,they both can be used to repair bone defect in immediately dental implant.
