目的:探讨锥形束CT(CBCT)在牙槽突裂植骨治疗中的应用价值。方法:对实验组15例牙槽突裂患者进行术前CBCT检测以确定牙槽突裂隙骨缺损量,术中按照所测定骨缺损量取髂骨松质骨并植骨;25例对照组患者直接根据术中评估取骨并植骨。所有患者术后6个月均进行CBCT检测,比较植骨效果。结果:术前应用CBCT指导植骨的病例组Image-J软件测量的术后移植成骨量与牙槽突裂隙骨缺失量比值为(0.935±0.16),对照组术后比值为(0.742±0.37),病例组植骨效果明显高于对照组,组间比较,差异具有统计学意义(P<0.05)。结论:CBCT可以准确检测牙槽突裂植骨修复效果,术前应用CBCT精确检测指导植骨量能够提高牙槽突裂植骨效果。
Objective: To investigate the value of cone beam computed tomography (CBCT) in alveolar cleft grafting. Methods: Fifteen cases of alveolar cleft in the experimental group were examined by preoperative CBCT to determine the amount of alveolar cleft defects. According to the measured bone defect volume, iliac cancellous bone and bone graft were obtained during the operation. Twenty-five patients in the control group Directly based on intraoperative assessment of bone and bone graft. All patients were tested CBCT 6 months after surgery to compare the effect of bone graft. Results: The ratio of postoperative bone graft to alveolar cleft bone loss measured by Image-J software before surgery was (0.935 ± 0.16) in control group and (0.742 ± 0.37) in control group ). The effect of bone graft in case group was significantly higher than that in control group. The difference between the two groups was statistically significant (P <0.05). Conclusion: CBCT can accurately detect the effect of alveolar cleft grafting, and preoperative application of CBCT to accurately detect the amount of bone graft can improve the effect of alveolar cleft grafting.
