Orthodontic management of anterior open bites is a demanding task for orthodontists. Molar intrusion as a primary means of open bite correction entails the need for appropriate anchorage. Orthodontic mini implants can provide the required mechanical support. The suggested procedure aims to reduce the risk of complications such as root damage or soft tissue irritations while minimizing overall complexity.
Three female patients aged 14, 18 and 19 years who decided against a surgical correction were treated with a device consisting of mini implants in the palatal slope, a palatal bar and intrusion cantilevers.
In all three patients, an open bite reduction of more than a millimeter occurred within four months. An anterior overbite of 2 mm or more could be established within 6 to 9 months.
The method presented in this article enables the practitioner to use mini implants in an easily accessible insertion site. A lab-side procedure is optional but not required.
正畸前牙开合的治疗是正畸医生面临的一项艰巨任务。磨牙内倾作为前牙开合矫正的主要手段，需要有适当的支抗。正畸迷你种植体可以提供所需的机械支撑。建议的治疗方案旨在降低并发症的风险，如牙根损伤或软组织刺激，同时尽量减少整体复杂性。
对 3 名年龄分别为 14、18 和 19 岁的女性患者采用一种装置进行治疗，该装置由腭斜坡上的迷你种植体、腭杆和内倾曲臂组成。
所有 3 名患者在 4 个月内实现了超过 1 毫米的前牙开合减少。6-9 个月内可建立 2 毫米或更多的前牙覆盖。
本文介绍的方法使医生能够在易于插入的部位使用迷你种植体。实验室侧的处理是可选的，但不是必需的。
