RESUMEN
Frenula consist of a mucosal fold in the labial, buccal and occasionally the lingual surface of the alveolar ridge. Their high attachment may cause orthodontic problem eg. [Diastima], prosthodontic problems eg. [Poor retention of denture], periodontic problems [gingival recession and inflammation] and speech problem [tongue tied in ligual frenum]. The removal of frenum could be done by surgical excision using scalpel through different techniques eg. [Vertical, Z plasty and hemostat]. Modern technology now offers an alternative mode of treatment like laser surgery. eight patients [14-75 years old] with freni indicated for excision were referred for laser clinic in police hospital. Laser used was diode with wavelength [810] nm [Oralaser Jet 20 - Germany], energy 1.8 Jul/sec and frequency 10,000 Hz using PPR1 [pulse pause relation] program with fiber tip diameter of 400 micron in contact mode. Laser safety measures were followed. showed dry and bloodless field during operation, no post operative swelling, no pain or discomfort, with normal healing process. as these were first cases to be treated by laser in Sudan, we suggest and stimulate the use of laser for soft tissue surgery because of its time saving, patients comfort and easy manipulation
