“…Even if the system in contrast, for example, to a current computerassisted CO 2 laser system is much more implementable and usable in a clinical environment [31], the manual guidance in some anatomical situations is not adequate and more sophisticated guidance is necessary. Therefore, the original design of the pilot study with harvesting bone grafts from the ramus region had to be changed.…”

The bone ablation technique using a (VSP) Er:YAG laser yielded superior clinical results without impairment of wound healing and in comparison to other laser systems, no significant time loss occurred. Yet, the missing depth control and the necessity of carefully handling the laser beam position and its angulation limit the use of a (VSP) Er:YAG laser to regions where a safe and fixed guidance of the laser beam is feasible.

“…Ultimately, a short-pulsed CO 2 -laser osteotome in a multipass mode using a computer-controlled galvanic beam scanner and an assisting water spray showed convincing results. 114,115 An altered superficial tissue layer (∼24 µm) was also detected by de Mello et al 116 after pulsed Er:YAG laser ablation in a rat tibia model. The modified zone was composed of 2 different sublayers: a superficial nonstructural layer (∼15 µm) and a deeper charred 1 (∼9 µm).…”

“…Together with the actual possibilities of modern 3-dimensional planning and computer-assisted surgery, the applications and indications of laser osteotomy can be even further improved and widened [23] . In several previous in vivo studies, a new computer-assisted CO 2 laser system was successfully implemented in the operation theater [24] . The main advantages of these CO 2 laser systems are the unprecedented precision of bone cuts with an almost arbitrary cut geometry which can be programmed and individualized on the computer.…”

Er:YAG Laser Osteotomy: Preliminary Clinical and Histological Results of a New Technique for Contact-Free Bone Surgery

et al. 2009

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.

In vivo animal trials with a scanning CO2 laser osteotome

Abstract: An effective CO(2) laser osteotomy without aggravating thermal side effects and healing delay is possible using the described irradiation technique. It allows an arbitrary cut geometry and may result in new advantageous bone surgery procedures.
