摘要： 目的    分析基于锥形束CT（cone beam CT，CBCT）的改良牙槽骨骨量测量方法的稳定性和准确性。方法    选取2023年2—10月在空军军医大学第三附属医院口腔外科行牙拔除术的70例患者的临床和影像学资料行回顾性分析，将术中牙拔除后的牙槽窝深度测量结果记为实测组。基于70例患者术后即刻CBCT影像资料，由3名医生分别采用3种方法对牙槽骨高度和宽度进行测量，分别记为研究组（改良CBCT测量法）、传统A组（Ivanova测量法）、传统B组（Pickert测量法）；其中，研究组还对牙槽窝深度进行测量，并与实测组比较。通过组内相关系数（intraclass correlation coefficient，ICC）一致性检验和方差分析比较研究组、传统A组、传统B组组内3名医生的牙槽骨高度和宽度测量结果差异。结果    组内一致性评价结果显示，研究组、传统A组和传统B组牙槽骨高度的ICC依次为0.972、0.961、0.908，牙槽骨宽度ICC依次为0.984、0.927、0.901，测量一致性均较好（均P < 0.001）。研究组3名医生的牙槽骨高度和宽度测量结果比较，差异均无统计学意义（F值分别为0.769、0.187，均P > 0.05）；传统A组和传统B组组内3名医生的牙槽骨高度和宽度测量结果比较，差异均有统计学意义（均P < 0.05）。研究组牙槽窝深度为（12.64 ± 2.52）mm，与实测组［（12.42 ± 2.27）mm］比较，差异无统计学意义（t = 1.536，P = 0.129）。结论    改良CBCT测量法具有较佳的牙槽骨骨量测量稳定性和准确性，建议在临床中推广应用。

Abstract: Objective    To analyze the stability and accuracy of improved alveolar bone mass measurement method based on cone beam CT. Methods    From February to October 2023，a retrospective analysis was conducted on clinical and radiographic data of 70 patients undergoing tooth extraction surgery in the Department of Oral Surgery，the Third Affiliated Hospital of Air Force Medical University. The measurements of alveolar socket depth after tooth extraction were recorded as the measured group. Based on immediate postoperative CBCT images of the 70 patients，three methods were used by three doctors to measure alveolar bone height and  alveolar bone width，respectively. These methods were labeled as the study group（improved CBCT measurement method），traditional group A（Ivanova′s measurement method），and traditional group B（Pickert′s measurement method）. In addition，the study group measured the alveolar depth and compared it with the measured group. Intraclass correlation coefficient（ICC）and analysis of variance were used to compare the differences of the three doctors in alveolar bone height and width measurements within each group. Results    As for intraclass consistency evaluation，the ICC values for alveolar bone height were 0.972，0.961，and 0.908 for the study group，traditional group A，and traditional group B，respectively，while for alveolar bone width，the ICC values were 0.984，0.927，and 0.901，respectively，demonstrating good measurement consistency（all P < 0.001）. There was no statistical significance in the measurement results of alveolar bone height and width among 3 doctors in the study group（F value was 0.769 and 0.187，respectively，P > 0.05）. There was statistical significance in the measurement results of alveolar bone height and width between the three doctors in the traditional group A and the traditional group B（P < 0.05）. The alveolar depth of the study group was（12.64 ± 2.52）mm，and there was no statistical significance compared with the measured group ［（12.42 ± 2.27）mm］（t =1.536，P = 0.129）. Conclusion    The modified CBCT measurement method demonstrates superior stability and accuracy in alveolar bone mass measurement. It is recommended for wider clinical application.
