A group of 40 patients, programmed for guided bone regeneration, randomly divided between laser-assisted technique and scalpel technique, were investigated to compare the postoperative evolution, healing time and prevalence of new bone formation, graft stability and inflammatory reactions. The guided bone regeneration technique associated with laser or scalpel technique offers reliable and predictable treatment results in the implant-prosthetic treatments. The accelerated healing time recommends the laser technique in the surgical procedures used for the alveolar augmentation.
