Surgically facilitated orthodontic treatment is increasingly being used, especially for adults, to facilitate tooth movements and reduce the duration of orthodontic treatment. The present article reports on an innovative, safe, and minimally invasive technique to perform flapless corticotomies using a dedicated surgical guide produced with a complete digital intraoral and laboratory workflow.
A 51-year-old man presented with maxillary and mandibular anterior crowding. He required rapid treatment with limited use of braces. Corticotomies were planned for both arches before the use of orthodontic appliances. The matching of the stereolithographic files obtained from the digital prints of the full arches and the cone beam computed tomography images allowed for the positioning of the cutting planes for corticisions. The guide was printed with a transparent, biocompatible, and photopolymerizable resin, and cold sterilized. Minimally invasive corticotomies were performed using a piezoelectric instrument. The orthodontic treatment started immediately after surgery.
No adverse events were recorded during surgery. The piezoelectric instrument was guided accurately, and precise application of the corticisions prevented all the anatomical elements from being injured. The healing was uneventful and the patient experienced no pain.
The present report shows that a surgical guide specifically and digitally produced for corticotomies allowed for the performance of a minimally invasive flapless technique and accurate piezosurgery. The use of such a guide was easy to implement, made the procedure safer, and reduced postoperative pain.
手术辅助正畸治疗正越来越多地被使用,尤其是在成人中,以促进牙齿移动并缩短正畸治疗时间。本文报道了一种创新、安全且微创的技术,该技术使用通过完整的数字化口内和实验室工作流程制作的专用手术导板来进行无瓣皮质切开术。
一名51岁男性患者,上颌和下颌前部拥挤。他需要在有限使用托槽的情况下进行快速治疗。在使用正畸矫治器之前,计划对上下牙弓均进行皮质切开术。从全牙弓数字印模和锥形束计算机断层扫描图像获得的立体光刻文件的匹配,使得能够确定皮质切开术的切割平面位置。该导板采用透明、生物相容且可光聚合的树脂打印,并进行冷消毒。使用压电器械进行微创皮质切开术。术后立即开始正畸治疗。
手术期间未记录到不良事件。压电器械引导精确,皮质切开术的精确实施避免了所有解剖结构受到损伤。愈合过程顺利,患者无疼痛。
本报告表明,专门为皮质切开术数字化制作的手术导板能够实现微创无瓣技术和精确的压电手术。使用这种导板易于实施,使手术更安全,并减轻了术后疼痛。
