Summary
Er:YAG laser frenectomy using the tunneling technique effectively reduced abnormal upper labial frenum size and diastema. This minimally invasive procedure preserved the incisive papilla with few complications.
Area of Science:
- Dentistry
- Oral Surgery
- Laser Dentistry
Background:
- Abnormal upper labial frenum (ULF) can cause gingival issues between central incisors.
- Er:YAG laser frenectomy offers advantages for ULF treatment.
Purpose of the Study:
- Evaluate the efficacy of Er:YAG laser frenectomy with the "tunnelization technique" for abnormal ULF elimination.
Main Methods:
- A cohort study of 20 patients undergoing ULF frenectomy with Er:YAG laser and tunneling technique.
- Morphological and clinical characterization of ULFs pre- and post-procedure.
Main Results:
- No intraoperative complications, with moderate bleeding in 60% of cases (no sutures needed).
- Only 10% required analgesics for mild postoperative pain.
- Significant reduction in frenulum size (P<0.001) and interincisal diastema (P=0.008) at 3 months.
- Incisive papillae preserved without defects.
Conclusions:
- Er:YAG laser frenectomy via tunneling is a suitable option for abnormal ULF.
- The technique ensures immediate incisive papilla preservation and reduces ULF size/position with minimal complications.
