**课程名称：** 牙齿正畸中的托槽定位技术 **课程概述：** 直丝弓预成型正畸托槽通过牙齿的面轴点（FA）将托槽放置于临床牙冠面轴点（FACC）的中点，从而在三维空间中定位牙齿。自1972年Andrews推广此技术以来，它已成为广泛应用的方法，目标是用直丝弓实现理想的近远中倾斜（Tip）和唇舌倾斜（Torque）。然而，托槽的精确放置至关重要。水平、轴向、垂直和基底定位的错误可能导致牙齿排列不齐，并因需要额外的弓丝调试而增加治疗时间。 尽管预成型托槽技术不断进步，但由于错颌畸形、操作失误或牙齿结构差异，在初次粘接时实现理想的托槽放置仍然充满挑战。研究表明，这种偏差需要额外的“细节调整”来纠正牙冠和牙根的排列。 间接粘接技术提供了一种解决方案，它允许更好的三维可视化和更精确的托槽放置。这种方法在实验室进行，通过定制的转移盘转移到患者口内，从而减少了就诊时间、弓丝调试的需要，以及对正畸医生和患者的身心压力。Hodge等，Koo等以及Aguirre等人的研究证实了间接粘接在高度、近远中位置和角度等方面的更高精确度。 尽管间接粘接存在耗时的实验室工作和额外成本等缺点，但其优势使其日益普及。各种改进也在不断涌现，以优化该技术及其临床效果。对于经验丰富的和初学正畸医生来说，熟练掌握托槽放置技巧对于避免治疗失败至关重要。本课程提供克服托槽定位误差的五大步骤，旨在缩短治疗时长、提升治疗效果并减少弓丝弯曲的需求。课程内容包括Damon托槽系统、MBT诊断图表的运用，以及通过口内扫描和3D建模设计的间接粘接、定制弓丝和托槽的优势。 This course provides a comprehensive approach to mastering bracket positioning, a critical factor in achieving successful orthodontic treatment with straight wire preadjusted appliances. It addresses common challenges faced during direct bonding and highlights the advantages of indirect bonding techniques, supported by scientific evidence. Learners will gain practical knowledge on improving accuracy, reducing treatment time, and minimizing the need for complex wire adjustments, making it valuable for both experienced professionals and those new to the field.
In straight wire preadjusted orthodontic appliances, brackets are designed to position teeth in three planes and are placed at the midpoint of the facial axis of the clinical crown (FACC), identified by the facial axis point (FA). Introduced by Andrews in 1972, this technique is now widely used, aiming to achieve excellent mesiodistal inclination (tip) and faciolingual inclination (torque) with a straight wire. However, precise bracket placement is crucial; errors in horizontal, axis, vertical, and base positioning can lead to misaligned teeth and increased treatment time due to necessary arch wire adjustments.Despite advancements in preadjusted appliances, achieving ideal bracket placement during initial bonding is often challenging due to malocclusion, operator error, or tooth structure variation. Studies have shown that these inaccuracies necessitate additional detailing to correct the alignment of crowns and roots.Indirect bonding techniques offer a solution, allowing better three-dimensional visualization and more accurate bracket placement. This method, performed in a laboratory and transferred to the patient's mouth using custom trays, reduces chair time, the need for wire adjustments, and physical and mental stress for both the orthodontist and the patient. Research by Hodge et al., Koo et al., and Aguirre et al. confirms the enhanced precision of indirect bonding in various aspects, such as height, mesiodistal position, and angulation.While indirect bonding has drawbacks, including time-consuming lab work and extra costs, its benefits have made it increasingly popular. Various modifications aim to improve the technique and its clinical outcomes. For orthodontists, both experienced and novice, mastering bracket placement is essential to avoid treatment failures. This course offers five steps to overcome bracket positioning errors, reduce treatment duration, enhance outcomes, and minimize the need for wire bending. It includes training on the Damon bracket system, MBT chart usage, and the benefits of indirect bonding and custom-made wires and brackets designed through intraoral scanning and 3D modeling.Summary:Straight wire preadjusted orthodontic appliances rely on precise bracket placement for proper tooth alignment. Introduced by Andrews in 1972, this method includes brackets placed at the midpoint of the facial axis of the clinical crown (FACC). Despite advancements, accurate bracket placement remains challenging, leading to misalignment and increased treatment times. Indirect bonding, performed in a lab and transferred with custom trays, offers more precision and reduces chair time, stress, and wire adjustments. Although it involves extra costs and lab work, its benefits have increased its popularity. Mastering bracket placement through courses can improve treatment outcomes and reduce treatment duration.
