摘要

在正畸学中,骨骼错颌的矫正一直是临床医生的一个挑战,特别是在非生长个体中,通常需要上颌或下颌骨骼基底的远端化。为了实现这一目标,研究人员采用了多种治疗方法,最近的一种是使用牙槽外骨螺钉,如颧下嵴(IZC)植入物。与拔牙和正颌手术等传统方法不同,该技术是边缘手术病例中可预测的全弓远端的有效和高效的治疗选择,不干扰根的运动,对患者依从性的依赖最小。为了实现身体控制的牙齿移位,必须仔细选择合适的方向和大小。因此,本病例报告试图测量上颌磨牙远端数量和模式,使用长臂颧下嵴(IZC)种植体作为一种可行的治疗选择,在18岁的女性患者骨骼II类模式,没有额外的微型种植体在前区侵入。

Maxillary total arch distalization with infra-zygomatic crest (IZC) bone screws for the correction of skeletal class II malocclusion: A case report
The correction of skeletal malocclusions in orthodontics has always been a contest for clinicians, especially in non-growing individuals, and often necessitates the distalization of maxillary or mandibular skeletal bases. To accomplish this, diverse treatment modalities have been employed by researchers, and the most recent one is the use of extra-alveolar bone screws such as Infra-zygomatic Crest (IZC) implants. Unlike conventional methods such as extraction and orthognathic surgery, this technique is an effective and efficient treatment alternative for predictable total arch distalization in borderline surgical cases, without interfering with the root movements and with minimal dependence on patient compliance. For achieving the displacement of teeth in a bodily controlled manner, an appropriate direction and magnitude of force must be carefully chosen. Therefore, this case report attempts to measure the amount and pattern of maxillary molar distalization using Infra-zygomatic Crest (IZC) implants with long power arms as a workable treatment option, in an 18-year-old female patient with a skeletal Class II pattern, with no extra mini-implants in the anterior region for intrusion.
