Objective: A 16-year-old man came to RSGMP Airlangga University with a complaint of a midline diastema in the maxilla which interfered with his appearance when smiling. After examination, it was found that there was an abnormal attachment of the superior labial frenulum so a frenectomy was needed. Methods: Anesthetize the operating area with a local anesthetic. The lips are retracted upwards. The frenulum is clamped using a hemostat until released. Irrigate the surgical area with saline. Perform suturing of the operating area with the interrupted technique using silk thread size 4 – 0. Result: one week post frenectomy shows redness, and slight edema in the mucobuccal fold region 11 21. One month post frenectomy it appears that wound healing is good, there is no pull from the frenulum. Conclusion: Frenectomy with the classical technique can correct the abnormal attachment of the frenulum
