珊瑚／骨髓复合人工骨修复颌骨缺损的临床应用研究

目的：评价珊瑚／骨髓复合人工骨修复颌骨缺损的疗效。方法：将珊瑚／骨髓复合人工骨用于充填9例颌骨囊肿和3例造釉细胞术后贵留的骨腔，术后1周、1、6和12个月通过临床和X线检查以评价其骨修复效果。结果：10例伤口Ⅰ期愈合，术后1个月缺损区有新骨形成；6个月缺损区可见大量成熟的骨组织，部分珊瑚被降解吸收；12个月珊瑚完全被宿主骨取代，缺损区得到完全修复。另有2例因伤口袭开需去除珊瑚骨。结论：珊瑚／骨髓复合人工骨可促进颌骨缺损的修复，是较理想的骨移植替代材料，减少缝合时伤口的张力是植骨成功的关键。

A clinical study on osseous regeneration in the jaw defects using a composite of coral and bone marrow

Objectives:To evaluate the efficiency of packing jaw defects with a composite of coral and bone marrow. Methods:Twelve patients (9 with jaw cyst and 3 with ameloblastoma) underwent enucleation of jaw lesion and packing with a composite of coral and bone marrow.Repair of the bone defects was evaluated at 1 week,1,6 and 12 months postoperatively by clinical examination and X ray films. Results:Wound healing after the operations on 10 patients was uneventful,and definite ossification around the implanted material could be detected at 1 month postoperatively.A lot of bone formation and partial resorption of coral were observed at 6 months postoperatively.Complete resorption of coral and complete bone repair were obtained at 12 months postoperatively.Wound breakdown was observed on two other patients,and the composite had to be removed completely. Conclusions:A composite of coral and bone marrow may enhances bone healing in jaw defects after cyst or ameloblastoma removal.
