This case report demonstrates an innovative technique involving concomitant correction of a traumatic extrusive luxated tooth, the mobility of which was being aggravated by anterior occlusal contacts, along with transverse rapid maxillary expansion to capitalize on the advantage of residual growth and simplify the need for comprehensive fixed orthodontic appliance. By incorporating a molar tube into the acrylic splint of the bonded Hyrax expander adjacent to the buccal surfaces and parallel to the buccal cusps of the maxillary first molars, effective intrusion of traumatically extruded upper incisor was achieved concomitantly using a modified intrusion arch during the passive stabilization period after expansion, thereby reducing treatment time. This enabled the immediate correction of extruded tooth and reduced the overall treatment duration and the complexity of post-expansion fixed mechanotherapy, improving compliance and uplifting the self-esteem of the patient. The modified bonded Hyrax assembly can serve as a versatile interim appliance for the simultaneous management of a variety of orthodontic problems such as crowding, spacing, and incisor proclination without compromising the basic integrity of the bonded assembly.
本病例报告展示了一种创新技术，该技术涉及同时矫正一颗因前牙咬合接触而加重松动的外伤性脱出性脱位牙，以及横向快速上颌扩弓，以利用剩余生长优势并简化对全面固定正畸矫治器的需求。通过在与上颌第一磨牙颊面相邻且平行于其颊尖的粘结式Hyrax扩弓器的丙烯酸夹板中纳入一个磨牙管，在扩弓后的被动稳定期使用改良的压低弓丝，实现了对外伤性脱出的上前牙的有效压低，从而缩短了治疗时间。这能够立即矫正脱出牙，减少了总体治疗时长以及扩弓后固定机械治疗的复杂性，提高了患者的依从性并提升了患者的自尊。改良的粘结式Hyrax组件可作为一种通用的临时矫治器，用于同时处理多种正畸问题，如牙列拥挤、牙间隙和切牙前倾，而不会损害粘结组件的基本完整性。
