“…Low ablation rates known from other laser systems have often prolonged laser-assisted surgical interventions in such a way that a clinical application is not practical due to the massive time loss [33] . This drawback could now be overcome by fast and contact-free Er:YAG laser osteotomy, although laser cutting speed was highly dependent on the depth of the cut and the experience of the surgeon.…”

Background: The purpose of this retrospective study was to evaluate the surgical performance, clinical usability and outcome of a new variable square pulsed (VSP) Er:YAG laser for bone cutting in oral and maxillofacial surgery. Materials and Methods: In 40 patients an Er:YAG laser with pulse energy of 1,000 mJ, pulse duration of 300 μs and a frequency of 12 Hz was used for different intraoral osteotomies. The spot size was 0.9 mm, and the handpiece was kept at a distance of 10 mm from the bone surface. Additionally, histological analyses of the fresh osteotomy rims of lasered bone were performed. Results: Er:YAG laser osteotomy revealed a remarkable cutting efficiency without any visible, negative, thermal side effects. There was no damage of adjacent soft tissue structures. However, depth control was limited to visual inspection. Histologically, a 5- to 10-μm-wide zone of a characteristic laser fingerprint appeared on the cut edges. However, there was no sign of thermal tissue damage to the underlying bone structures. Conclusions: VSP Er:YAG laser osteotomy is clinically practicable without any signs of charred tissue and wound healing disturbances. However, the lack of depth control and the necessity for careful handling are still technical limitations to be overcome.

“…17 As for the Er:YAG laser, one of the main advantages of ultraviolet (UV) light-induced ablation by the excimer laser is the exact bone removal without any thermal adverse effects. 18 However, there are several limiting factors for the application of the excimer laser in bone surgery.…”

“…Additional water cooling does not disturb the ablation process. Therefore, photoablation is more or less an athermal ablation process which would offer ideal conditions for bone cutting 83,84. However, extremely low ablation rates per pulse and difficult handling of excimer lasers reduce their scale of clinical usability.…”

The erbium-doped yttrium aluminium garnet (Er:YAG) laser has emerged as a possible alternative to conventional methods of bone ablation because of its wavelength of 2.94 μm, which coincides with the absorption peak of water. Over the last decades in several experimental and clinical studies, the widespread initial assumption that light amplification for stimulated emission of radiation (laser) osteotomy inevitably provokes profound tissue damage and delayed wound healing has been refuted. In addition, the supposed disadvantage of prolonged osteotomy times could be overcome by modern short-pulsed Er:YAG laser systems. Currently, the limiting factors for a routine application of lasers for bone ablation are mainly technical drawbacks such as missing depth control and a difficult and safe guidance of the laser beam. This article gives a short overview of the development process and current possibilities of noncontact Er:YAG laser osteotomy in oral and implant surgery.
