RESUMO
Introduction: periosteal releasing incision [PRI] is nearly always essential to advance the flap sufficiently for a tension-free flap closure in bone augmentation procedures. However, hematoma, swelling, and pain are recognized as the main consequences of PRI with scalpel. The aim of this case series was to investigate the effectiveness of laser-assisted PRI in guided bone regeneration [GBR] procedure. In addition, postoperative hematoma, swelling, and pain and implant success were assessed
Methods: seventeen patients needed GBR were included in this study. Diode laser [940 nm, 2 W, pulse interval: 1 ms, pulse length: 1 ms, contact mode, 400-micro m fiber tip] was used in a contact mode to cut the periosteum to create a tension-free flap. Facial hematoma, swelling, pain, and the number of consumed nonsteroidal anti-inflammatory drugs [NSAIDs] were measured for the six postoperative days. Six months after implant loading, implant success was evaluated
Results: minimal bleeding was encountered during the procedure. A tension-free primary closure of the flap was achieved in all cases. The clinical healing of the surgical area was uneventful. None of the patients experienced hematoma, ecchymosis, or intense swelling after surgery. The mean value of maximum pain [visual analogue scale - VAS] was 20.59 +/- 12.10 mm [mild pain]. Patients did not need to use NSAID after four postoperative days. All implants were successful and functional and none of them failed after 6 months of implant loading
Conclusion: this study revealed the effectiveness of laser-assisted PRI in GBR procedure. This technique was accompanied with minimal sequelae at the first postoperative week. All implants were successful and no complication was noted during the course of this study
