摘要
目的和背景:众所周知,四螺旋矫治器能够治疗上颌缺损儿童的后交叉咬合。一些学者通过对矫治器进行改良,也将其用于治疗单侧上颌缺损引起的单侧交叉咬合。本研究的目的是使用新改良的四螺旋矫治器治疗单侧交叉咬合:一名 8 岁的女性患者因上颌牙弓不对称导致多颗牙齿缺失和单侧后交叉咬合。使用一种独特的方法在石膏上测量了单侧不对称的程度。为治疗单侧后交叉咬合,粘接了一个改良的四螺旋体,30 天后就得到了矫正。粘接的南斯腭弓可作为空间维持器和固位矫治器:结论:使用改良四螺旋成功治疗了单侧后交叉咬合:本文重点介绍了一种用于治疗单侧后方交叉咬合的四螺旋新改良方法,以及一种测量上颌不对称的新方法。该改良设计被称为 "双螺旋",因为它从经典的四螺旋设计中取消了两个螺旋:D'souza OK, Chalakkal P, de Noronha de Ataide I. 四螺旋的改良:"双螺旋"。Int J Clin Pediatr Dent 2024;17(7):822-825.
Aim and background: The quad helix is well known for its ability to treat posterior crossbites in children with maxillary deficiency. A few authors have also used it for the treatment of unilateral crossbite due to unilateral maxillary deficiency by incorporating modifications in the appliance. The aim was to treat a unilateral crossbite using a newly modified quad helix.
Case description: An 8-year-old female patient had presented with multiple missing teeth and a unilateral posterior crossbite due to an asymmetric maxillary arch. The amount of unilateral asymmetry was measured using a unique method over the cast. A modified quad helix was cemented to treat the unilateral posterior crossbite, and correction was obtained in 30 days. A Nance palatal arch was cemented which functioned as a space maintainer and a retention appliance.
Conclusion: The posterior unilateral crossbite was treated successfully with the modified quad helix.
Clinical significance: This article highlights a new modification of the quad helix for treating unilateral posterior crossbite and a new method of measuring maxillary asymmetry. The modification has been termed as a "bi helix" since it eliminates two helices from the classic quad helix design.
