摘要

评估半自动三维数字设置过程在预测唇侧固定矫治器矫治效果方面的准确性。25 名患有 I 类错牙合畸形和中度牙齿拥挤的成年患者(18 至 24 岁)被纳入前瞻性研究,并通过直丝技术接受了双颌矫治。治疗开始前,通过 Orthoanalyzer 软件(3Shape®,丹麦哥本哈根)对每位患者进行了预测治疗结果的半自动数字模拟设置,以获得预测模型。通过三维叠加方法将其与最终结果模型进行比较。度量变量和彩色编码距离图检查用于检测数字设置预测实际治疗结果的准确程度。预测模型和最终模型的叠加牙弓之间的平均绝对距离(MAD)分别为叠加到上颚后为 0.77 ± 0.13 毫米,叠加到上颌牙弓后为 0.52 ± 0.06 毫米,叠加到下颌牙弓后为 0.55 ± 0.15 毫米。腭侧参照区的 MAD 为 0.09 ± 0.04 mm。彩色编码距离图的可视化显示,数字设置在少数病例中准确预测了最终的牙齿位置。近一半病例的上下牙弓向后加宽,前牙位于腭/舌侧或倾斜,而其余病例的误差仍在 2-3 毫米以内,分布于整个牙弓,没有明显的规律。对于中度拥挤的 I 类病例,半自动预测唇侧固定矫治器治疗结果的准确性还不够。虽然平均测量结果显示偏差小于 1 毫米,但对单个彩色编码距离图的检查显示,模拟结果与实际结果之间存在显著差异。

Digital setup accuracy for moderate crowding correction with fixed orthodontic appliances: a prospective study
To evaluate the accuracy of a semi-automatic 3D digital setup process in predicting the orthodontic treatment outcome achieved by labial fixed appliances. Twenty-five adult patients (18 to 24 years old) with class I malocclusion and moderate crowding were prospectively enrolled and received treatment on both jaws through the straight-wire technique. Prior to treatment commencement, a semi-automatic digital setup simulating the predicted treatment outcome was performed for each patient through Orthoanalyzer software (3Shape®, Copenhagen, Denmark) to obtain the prediction model. This was compared to the final outcome model through 3D superimposition methods. Metric variables and inspection of color-coded distance maps were used to detect how accurately the digital setup predicts the actual treatment outcome. The mean absolute distances (MAD) between the superimposed dental arches of the predicted and the final models were: 0.77 ± 0.13 mm following superimposition on the palate, 0.52 ± 0.06 mm following superimposition on the maxillary dental arch, and 0.55 ± 0.15 mm following superimposition on the mandibular dental arch. The MAD at the palatal reference area was 0.09 ± 0.04 mm. Visualization of color-coded distance maps indicated that the digital setup accurately predicted the final teeth position in a few cases. Almost half of the cases had posteriorly wider upper and lower dental arches and palatally/lingually positioned or inclined anterior teeth, whereas the rest still showed errors within 2–3 mm, distributed over the entire dental arches with no distinct pattern. The accuracy of semi-automatic prediction of the labial fixed appliance treatment outcome in Class I cases with moderate crowding is not yet sufficient. While average measures showed deviations less than 1 mm, examination of individual color-coded distance maps revealed significant disparities between the simulated and the actual results.

期刊介绍: Progress in Orthodontics is a fully open access, international journal owned by the Italian Society of Orthodontics and published under the brand SpringerOpen. The Society is currently covering all publication costs so there are no article processing charges for authors. It is a premier journal of international scope that fosters orthodontic research, including both basic research and development of innovative clinical techniques, with an emphasis on the following areas: • Mechanisms to improve orthodontics • Clinical studies and control animal studies • Orthodontics and genetics, genomics • Temporomandibular joint (TMJ) control clinical trials • Efficacy of orthodontic appliances and animal models • Systematic reviews and meta analyses • Mechanisms to speed orthodontic treatment Progress in Orthodontics will consider for publication only meritorious and original contributions. These may be: • Original articles reporting the findings of clinical trials, clinically relevant basic scientific investigations, or novel therapeutic or diagnostic systems • Review articles on current topics • Articles on novel techniques and clinical tools • Articles of contemporary interest
