RESUMO

O objetivo deste trabalho foi demonstrar o papel do laser diodo de alta intensidade (980 nm, Theralase, DMC Equipamentos – São Carlos) na coagulação e como forma de proteção da ferida cirúrgica palatina, a partir de três relatos de caso clínico em pacientes com área palatina normal e saudável, com indicação de remoção de enxertos gengivais livres ou enxertos de tecido conjuntivo desepitelizado. O procedimento cirúrgico com laser de alta intensidade demonstrou efeito terapêutico, especialmente na redução da morbidade e dor da ferida palatina, uma vez que a ingestão de analgésicos no pós-operatório foi mínima. No entanto, devido ao risco de complicações, como sangramento trans e pós-operatório, seu efeito como proteção biológica isolada é incerto.

Palavras-chave – Periodontia; Fotocoagulação a laser; Enxerto autólogo.

ABSTRACT

The aim of this paper was to demonstrate the role of the high-intensity Diode Laser (980 nm, Theralase, DMC Equipment – São Carlos) in coagulation and as an alternative to protect the palatal surgical wound. With three case reports of patients with normal and healthy palatal area, with indication for removal of free gingival grafts or de-epithelialized connective tissue grafts. The surgical procedure with high-intensity laser demonstrated a therapeutic effect, mainly in reducing morbidity and pain in the palatal wound, since the intake of postoperative analgesics was minimal. However, due to the risk of complications, such as intra and postoperative bleeding, its effect as isolated biological protection is uncertain.

Key words – Periodontics; Laser coagulation; Autografting.
