摘　　要：目的研究锥形束CT(cone beam CT,CBCT)在牙槽突裂植骨修复术前预测植骨量的准确性。方法选择14例单侧牙槽突裂患者为研究对象,术前通过CBCT扫描获取患者上颌骨影像数据并导入Mimics软件,用该软件测量牙槽突裂骨缺损体积。在术中通过5 mL注射器测量植入牙槽突裂隙中的松质骨骨量,获得牙槽突裂骨缺损的实际体积,并与术前测量结果进行对比分析。结果 14例患者接受了牙槽突裂植骨术,手术均顺利完成,术前用CBCT和Mimics软件测量得到的牙槽突裂骨缺损体积为(2.78±0.70)mL,术中实际测量得到的牙槽突裂骨缺损体积为(2.88±0.70)mL,差异无统计学意义(P>0.05),术前CBCT预测牙槽突裂骨缺损体积准确率为(95.09±2.56)%。结论术前CBCT结合Mimics软件可精确计算牙槽突裂骨缺损体积。Objective To evaluate the accuracy of cone beam CT （ CBCT） in calculating the volume of the bone de-fect in alveolar cleft. Methods 14 patients with unilateral alveolar cleft were included in this study. Their image data were collected by CBCT scan and imported in the Mimics 10. 01 software. The volume of the bone defect in alveolar cleft was calculated by Mimics 10. 01 software. The real bone volumes transplanted during operation were measured by sterile syringes and were compared with preoperative CBCT data. Results The volume of bone defect from CBCT calculation was （ 2. 78 ± 0. 70） mL, while the real volume obtained in operation was （ 2. 88 ± 0. 70） mL. There was no significant difference between the CBCT data and the real bone defect （ P〉0. 05） . The accuracy of CBCT in predicting bone defect volume was （ 95. 09 ± 2. 56）%. Conclusion The combination of CBCT data and Mimics software can evaluate the bone defect volume in alveolar cleft accurately.
