Objective. The aim of this study was to assess the ability of Er:YAG laser to remove by excision torus mandibularis and to smooth torus palatinus exostosis. Materials and Methods. Torus mandibularis (TM) and torus palatinus (TP) were surgically eliminated via the Er:YAG laser using the following parameters: TM: output power ranging from 500 to 1000 mJ, frequency from 20 to 30 Hz, sapphire tips (diameter 0.8 mm), air-water spray (ratio 5/5), pulse duration 150 μsec, fluence ranging from 99592 J/cm(2) to 199044,586 J/cm(2). TP: a peeling technique was used to eliminate TP, as excision by slicing being impossible here. Results. TM: excision was obtained after 12730 pulses. TP: smoothing technique took more time compared with excision. Once peeling was considered to be accomplished, the use of a surgical rasp was necessary to eliminate bone spicules that could delay the wound to heal in good conditions. Conclusion. Er:YAG excision (TM) or Er:YAG peeling (TP) are safe clinical techniques easy to practice even if the time required for excision or surface smoothing is more than the time required with bony burs and high speed instruments.
目的。本研究的目的是评估铒钇铝石榴石（Er:YAG）激光切除下颌隆突以及使腭隆突骨赘平滑的能力。材料与方法。使用以下参数通过Er:YAG激光手术切除下颌隆突（TM）和腭隆突（TP）：TM：输出功率范围为500至1000 mJ，频率为20至30 Hz，蓝宝石尖端（直径0.8 mm），空气 - 水喷雾（比例5/5），脉冲持续时间150 μsec，能量密度范围为99592 J/cm²至199044586 J/cm²。TP：采用剥离技术切除TP，因为此处无法通过切片切除。结果。TM：12730次脉冲后完成切除。TP：与切除相比，平滑技术耗时更长。一旦认为剥离完成，就需要使用手术锉来去除可能延迟伤口良好愈合的骨碎片。结论。Er:YAG切除（TM）或Er:YAG剥离（TP）是安全的临床技术，即使切除或表面平滑所需的时间比使用骨钻和高速器械所需的时间长，也易于操作。
