Harvesting of intraoral autogenous block grafts from the chin and ramus region: Preliminary results with a variable square pulse Er:YAG laser

Abstract

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.

Application of interconnected porous hydroxyapatite ceramic block for onlay block bone grafting in implant treatment: A case report (Review)

“…However, intraoral grafts have been reported to have various drawbacks, such as need for an additional surgical procedure to procure the bone graft material, increased operative time, graft bone limitations, post-operative pain, altered sensation in mandibular teeth, neurosensory disturbances, nerve paresthesia, and mandibular fracture (8,14). In addition, an autogenous bone block usually undergoes extensive resorption during healing (15), which may result in implant failure from osseointegration loss leading to reduced bone-to-implant contact and an unfavorable outcome.…”

“…Furthermore, several reports have noted that implant treatment with an autogenous onlay block bone graft for horizontal or vertical alveolar ridge atrophy results in bone gain and high rates of implant success (3)(4)(5)(6). However, autogenous block bone grafting also has some disadvantages, such as limited availability of grafts with sufficient size and shape, and risk of donor site morbidity, including long-lasting pain, fracture, and nerve damage (7)(8)(9). In addition, other problems associated with resorption of the grafted bone during the healing process remain.…”

The use of lasers for direct pulp capping

“…Thus, the Er:YAG laser has an excellent capacity for ablating both soft and hard tissues with minimal thermal side-effects. It has been applied for bone surgery in oral surgery, dentistry, implant dentistry, and otolaryngology (68)(69)(70)(71). The Erbium, Chromium: Yttrium-ScandiumGallium Garnet (Er,Cr:YSGG) laser has a 2,780 nm wavelength, which is more highly absorbed by OH ions than by water molecules (72) and performs in a manner similar to the Er:YAG laser.…”

Advances in bone surgery: the Er:YAG laser in oral surgery and implant dentistry

“…In a further clinical study, the own group used the same laser system for harvesting intraoral bone grafts with a spot size of 0.9 mm at a distance of about 10 mm from the bone surface. 149 The laser settings used for bone cutting were pulse energy of 1,000 mJ, pulse duration of 300 µs, and a frequency of 12 Hz (energy density, 157 J/cm 2 ). By contact-free laser guidance over the surface, various cut courses with straight or curved parts could be easily combined without the need of changing any surgical tips.…”
