Laser labial frenectomy: a simplified and predictable technique. Retrospective clinical study

Area of Science:

• Pediatric Dentistry
• Oral Surgery
• Laser Dentistry

Background:

• Anomalous maxillary median labial frenum can cause dental issues like persistent diastema and gingival irritation.
• Early intervention with frenum repositioning may be indicated in conjunction with orthodontic therapy for children.

Purpose of the Study:

• To introduce a minimally invasive, safe, easy, reproducible, and predictable surgical frenum repositioning technique.
• To identify clinical situations warranting labial frenectomy with early orthodontic treatment in children.
• To retrospectively assess the clinical outcomes of this laser-assisted technique.

Main Methods:

• Twenty frenectomies were performed on children aged 8-10 years using an Er:YAG laser.
• The laser was set at 150mJ, 2.25-3.0W, with a pulse rate of 15-20 Hz and water spray.
• Follow-up assessments were conducted at multiple intervals up to 4 years post-procedure.

Main Results:

• All patients reported minimal to no post-operative pain or bleeding.
• The procedure was well-tolerated and deemed "acceptable" by all child participants.
• No instances of frenum recurrence were observed during the 4-year follow-up period.

Conclusions:

• Er:YAG laser frenectomy significantly reduced operating time and the need for local anesthetic and sutures.
• The surgical technique minimized post-operative discomfort and complications, leading to stable healing.
• The laser-assisted procedure was fully accepted by pediatric patients, offering predictable long-term results.
