INTRODUCTION
This study aimed to evaluate whether viewing digital treatment simulations influenced orthodontic treatment planning decisions or practitioners' confidence in their selected plans.
METHODS
Records of 6 patients representing different case types (eg, missing teeth, crowding, sagittal discrepancies) were collected. A total of 22 orthodontists and 7 orthodontic residents viewed these records and formulated treatment plans for each case, indicating their most recommended plan and up to 2 alternative plans. After treatment planning each case, digital setups of each treatment plan indicated by the practitioner were shown. The practitioners were then asked if they still recommended their original plan, or if they would now recommend a different plan. Their confidence levels in the success of their plans were recorded before and after viewing the setups.
RESULTS
After viewing the digital setups, there was a significant change in the treatment plan for 9.2% of the cases. These included modifications like changing the extraction pattern or proposing space closure rather than opening space for an implant. In an additional 14.4% of the cases, treatment plans underwent partial changes, like adding interproximal reduction or temporary anchorage devices. Practitioner confidence levels increased after viewing the setups. In cases where the treatment plan changed, the practitioner's confidence level in the plan increased the most, and the final confidence level was uniformly high among all practitioners. Practitioners reported the most helpful features of digital setups were the ability to superimpose the setup with the original model, determine the amount of tooth movement needed, check the final incisal relationship (overjet and overbite), and establish the amount of interproximal reduction required.
CONCLUSIONS
Viewing digital setups resulted in changes to the treatment plans in about 24% of the cases. The use of digital setups was associated with higher levels of confidence in the selected plans.
简介
本研究旨在评估观看数字化治疗模拟是否会影响正畸治疗计划决策或医生对所选计划的信心。
方法
收集了代表不同病例类型（如缺牙、拥挤、矢状不调）的 6 名患者的记录。共有 22 名正畸医生和 7 名正畸住院医师查看了这些记录，并为每个病例制定了治疗计划，为每个病例指明了他们最推荐的计划和最多 2 个替代计划。在为每个病例进行治疗计划后，显示医生指示的每个治疗计划的数字设置。然后，医生被问及他们是否仍然推荐他们的原始计划，或者他们现在是否会推荐不同的计划。在查看设置之前和之后，记录了他们对计划成功的信心水平。
结果
在观看数字设置后，有 9.2%的病例治疗计划发生了显著变化。这些变化包括改变拔牙模式或提出关闭间隙而不是为种植体打开间隙等。在另外 14.4%的病例中，治疗计划进行了部分更改，例如添加邻面减径或临时锚固装置。医生的信心水平在观看设置后有所提高。在治疗计划发生变化的病例中，医生对计划的信心水平提高最多，所有医生的最终信心水平都很高。医生报告数字设置最有帮助的功能是能够将设置与原始模型叠加，确定所需的牙齿移动量，检查最终切端关系（覆盖和覆颌），并确定所需的邻面减径量。
结论
约 24%的病例中，观看数字化设置导致治疗计划发生变化。使用数字设置与所选计划的信心水平提高有关。
