Alveolar bone coverage can be diagnosed through cone beam computed tomography (CBCT) and this information can prevent orthodontic tooth movement beyond the biological limit.
This study evaluated the impact of the bone coverage (BC) diagnosis by CBCT in the orthodontists' planning.
One hundred fifty-nine Brazilian orthodontists suggested treatment plans for six patients at two different times, using two sequential questionnaires. The first questionnaire consisted of extra and intra-oral photographs, one panoramic radiograph; one lateral cephalometric radiograph with Steiner and Tweed analysis, and the patient chief complaint. The second questionnaire included the same presentations of cases with tomographic images and the radiologist's report. The McNemar test assessed the difference between the first and the second treatment plans.
In all six cases, most participants changed the treatment plan after evaluating the CBCT images and the radiologist's report (93.7% in case 5, 78.6% in case 4, 74.2% in case 3, 69.8% in case 6, 66% in case 2 and 61% in case 1; p≤0.01).
The evaluation of bone coverage through CBCT images has a substantial impact on the orthodontic diagnosis and planning of the Brazilian orthodontists.
牙槽骨覆盖可以通过锥形束 CT（CBCT）进行诊断，这些信息可以防止正畸牙齿移动超出生物学极限。
本研究评估了 CBCT 对骨覆盖（BC）的诊断对正畸医生的治疗计划的影响。
159 名巴西正畸医生在两次不同的时间使用两个连续的问卷为六名患者制定治疗计划。第一个问卷包括口外和口内照片、一张全景片、一张带有 Steiner 和 Tweed 分析的侧位头颅侧位片，以及患者的主要诉求。第二个问卷包括相同的病例呈现方式，外加断层扫描图像和放射科医生的报告。McNemar 检验评估了第一次和第二次治疗计划之间的差异。
在所有六例中，大多数参与者在评估 CBCT 图像和放射科医生的报告后改变了治疗计划（病例 5 中为 93.7%，病例 4 中为 78.6%，病例 3 中为 74.2%，病例 6 中为 69.8%，病例 2 中为 66%，病例 1 中为 61%；p≤0.01）。
通过 CBCT 图像评估骨覆盖对巴西正畸医生的正畸诊断和治疗计划有重大影响。
