After the mandibular third molars, the maxillary canines are the most displaced or impacted teeth in permanent dentition. Surgical-orthodontic disimpaction of impacted canines, followed by aesthetic reconstructions, can be a successful treatment choice.
The aim of this case report was to describe the smile restoration through simultaneous surgical disimpaction of the two upper permanent canines in a 13-year-old patient who also presented with agenesis of the right upper lateral incisor and a conoid-shaped left upper lateral incisor.
The present case report followed the Care Checklist For Case Reports. After having completed the multibrackets fixed orthodontic therapy phase necessary for the preparation of the anchorage, avulsions of the upper deciduous canines were carried out, followed by the making of surgical full thickness palatal flap in order to perform traction of the permanent canines, and an orthodontic eyelet with passive metal looped ligatures was applied. One week after the surgery, traction was started with Crescini-double arch technique. Subsequently, the avulsion of elements 2.2 and 5.2 were executed. At the end of orthodontic treatment, in order to optimise the aesthetics and function of the canines, a restorative treatment was carried out.
After the surgical creation of a palatal flap, the disimpaction of the two upper canines, using the double arch technique, allowed the teeth to be moved into the desired position on the upper arch.
在下颌第三磨牙之后,上颌尖牙是恒牙列中移位或阻生最常见的牙齿。对阻生尖牙进行外科正畸牵引,随后进行美学修复,可能是一种成功的治疗选择。
本病例报告的目的是描述一名13岁患者同时外科牵引两颗上颌恒牙尖牙的微笑修复过程,该患者还伴有右上侧切牙先天缺失和左上侧切牙呈锥形。
本病例报告遵循病例报告护理清单。在完成制备支抗所需的多托槽固定正畸治疗阶段后,拔除上颌乳尖牙,然后制作腭部全厚瓣以牵引恒牙尖牙,并应用带有被动金属环扎丝的正畸带环。术后一周,采用Crescini双弓技术开始牵引。随后,拔除2.2和5.2牙位的牙齿。正畸治疗结束后,为了优化尖牙的美学和功能,进行了修复治疗。
在外科制作腭瓣后,使用双弓技术牵引两颗上颌尖牙,使牙齿能够移动到上颌弓的理想位置。
