Abstract
Introduction: During orthodontic treatment, temporary anchoring devices (TADs) are used to restrain tooth movement. They are a relatively recent addition to the dental toolkit.
Aim: As TADs have limitations, Dr. Eric Lieu of Taiwan developed Infra Zygomatic Crest (IZC) screws which are placed between the maxillary second premolar at the bony crest.
Treatment planning: The goal of this case study is to emphasize the value of anatomy, site selection, and IZC retrieval in the event of an accident. Cone beam computed tomography was used as a diagnostic tool for the precise location of the displaced IZC and immediate surgical retrieval was done under local anesthesia from the infratemporal space to prevent further complications.
Takeaway lessons: Orthodontists knowledge of soft tissue and hard tissue anatomy and precise positioning is crucial for successful TAD implantation.
介绍：在正畸治疗过程中，临时固定装置（TAD）被用来限制牙齿的移动。目的：由于临时固定装置存在局限性，台湾的 Eric Lieu 医生开发了颧骨嵴内螺钉（IZC），将其放置在骨嵴处的上颌第二前磨牙之间：本病例研究的目的是强调解剖、部位选择和意外情况下 IZC 取出的价值。锥形束计算机断层扫描被用作诊断工具，以确定移位的IZC的准确位置，并在局部麻醉下立即从颞下间隙进行手术取出，以防止进一步的并发症：启示：正畸医生对软组织和硬组织解剖的了解以及精确定位是成功植入 TAD 的关键。
