Lasers are a relatively new addition to the orthodontist's armamentarium. This article reviews the fundamental basic science of available soft-tissue lasers, with an emphasis on diode lasers, and discusses various adjunct applications of the diode laser for soft-tissue orthodontic procedures. Diode lasers function by cutting with an initiated hot tip and produce minimal to no interaction with healthy dental hard tissue, making them suitable for soft-tissue procedures. The contact cutting mode provides enhanced bloodless site visibility and facility to perform delicate soft tissue procedures, which is important in areas with difficult access. Such adjunctive uses include laser gingivectomy to improve oral hygiene or bracket positioning, esthetic laser gingival recontouring, and laser exposure of superficially impacted teeth. Selected cases treated with a 940-nm indium-gallium-arsenide-phosphide (InGaAsP) diode laser will be presented.
激光是正畸医生治疗手段中相对较新的一项。本文回顾了现有软组织激光的基础科学知识，重点介绍二极管激光，并讨论了二极管激光在软组织正畸手术中的各种辅助应用。二极管激光通过启动热尖端进行切割，与健康的牙齿硬组织产生的相互作用极小或没有，这使其适用于软组织手术。接触切割模式可提高无血手术部位的可视性，并便于进行精细的软组织手术，这在难以操作的区域非常重要。此类辅助用途包括激光牙龈切除术以改善口腔卫生或进行托槽定位、美学激光牙龈重塑以及浅表埋伏牙的激光暴露。本文将展示使用940纳米铟镓砷磷（InGaAsP）二极管激光治疗的选定病例。
