The present case series demonstrates the efficacy of an 810 nm diode laser for the surgical management of oral soft tissues related to orthodontic treatment. Three orthodontic patients aged 16-23 years underwent operculectomy, ablation of soft-tissue overgrowth over orthodontic appliance and gingivectomy along with gingival recontouring procedures, respectively, using the 810 nm diode laser. In each case, an initiated laser fibre tip was utilised to ablate the tissue at the treatment site by making a light contact with the tissue (average power output = 1-1.6 W, continuous wave emission mode, fibre diameter = 400 µm, spot size = 0.0013 cm, energy density = 124.9-199.9 J/cm, irradiance = 796-1273 W/cm, total energy dose = 300-480 J). The maximum total length of treatment was 300 s (5 min). None of the patients reported any instantaneous or delayed postoperative complications over six months. Utilisation of the 810 nm diode laser for surgical management of oral soft tissues related to orthodontic treatments can be considered safe, effective and justifiable over the conventional scalpel technique; however, it must be performed by trained and experienced clinicians only.
本病例系列展示了 810nm 二极管激光在正畸治疗相关口腔软组织手术管理中的疗效。3 名年龄在 16-23 岁的正畸患者分别接受了 810nm 二极管激光的腭切除术、正畸器械上软组织过度生长的消融术和牙龈切除术以及牙龈整形术。在每种情况下，使用启动的激光光纤尖端通过与组织轻触来消融治疗部位的组织（平均功率输出=1-1.6W，连续波发射模式，光纤直径=400μm，光斑大小=0.0013cm，能量密度=124.9-199.9J/cm，辐照度=796-1273W/cm，总能量剂量=300-480J）。治疗的最长总时间为 300s（5 分钟）。在 6 个月内，没有患者报告任何即刻或延迟的术后并发症。与传统手术刀技术相比，810nm 二极管激光用于正畸治疗相关口腔软组织的手术管理可被认为是安全、有效和合理的；然而，它只能由经过培训和经验丰富的临床医生进行操作。
