In straight wire preadjusted appliances, all the information required to position the teeth in three planes is included in the brackets placed at the midpoint of the facial axis of the clinical crown, defined by facial axis point (FA). Central to this technique is the bracket placement.Preadjusted orthodontic appliances cannot get the right tooth position with a straight wire because of the inaccuracy of bracket placement. Horizontal, axis, vertical, and base are the most common bracket placement errors.The aim of this paper was to describe a bracket positioner to fix the brackets accurately (Q) on FA point (FAQ.FIX®) in direct or indirect bonding.
After the development of a prototype, a FAQ.FIX® along with a Bracket Placement Clinical Chart was developed and thus described.
FAQ.FIX® along with the Bracket Placement Clinical Chart may facilitate the accuracy in bracket placement on FA point avoiding the most common bracket placement errors regardless the operator skill, even in particular or difficult case.
FAQ.FIX®may represent a significant improvement in the bracket placement compared to the bracket eye and the traditional gauges positioning. Further studies will be needed to verify the clinical efficacy.
在直丝弓预成矫治器中,将牙齿在三个平面上定位所需的所有信息都包含在放置于临床牙冠面轴中点(由面轴点(FA)定义)的托槽中。该技术的核心是托槽定位。由于托槽定位不准确,预成正畸矫治器无法通过直丝获得正确的牙齿位置。水平、轴、垂直和基底是最常见的托槽定位错误。本文的目的是描述一种托槽定位器,用于在直接或间接粘接时将托槽准确地固定在FA点(FAQ.FIX®)上。
在开发出原型后,开发并描述了一种FAQ.FIX®以及一份托槽定位临床图表。
FAQ.FIX®与托槽定位临床图表一起,可能有助于在FA点准确放置托槽,避免最常见的托槽定位错误,无论操作者的技术如何,即使在特殊或困难的病例中也是如此。
与托槽定位孔和传统测量仪定位相比,FAQ.FIX®可能在托槽定位方面有显著改进。需要进一步研究来验证其临床疗效。
