Labial frenum is a common anatomical formation that connects a mobile structure to a fixed one. Its insertion is located on the lips and in the alveolar ridge at the midline. In some cases, it may present hypertrophy or atypical insertion in the alveolar ridge between the central incisors, causing diastema, malocclusion, periodontal disease, aesthetic problems, and dysphonia. In these situations, labial frenectomy is indicated and has the purpose of restoring the anatomy of the region and treating or preventing the disorders described. The present study aims to report a clinical case, which an upper labial frenectomy was performed in a classic technique adaptation and to review the literature about the procedure. The described technique has great relevance in clinical practice due to its easy execution, low cost, and satisfactory result.

Nerve damage during third molars removal is an inherent risk of the procedure due to the anatomical proximity of these structures. Coronectomy is an effective technique that can reduce the risk of developing paresthesia caused by this injury. The present study aims to report a clinical case in which the coronectomy was performed describing its technique. The procedure was performed on a 25-year-old male patient, with third molars removal indication. The radiological exam suggested an intimate relationship between the lower right third molar roots and the mandibular canal. The coronectomy technique was performed under local anesthesia and the follow-up was performed after seven days, four months and four years. One week after surgery patient reported good recovery and does not showed radiographic signs or clinical symptoms of sensory or other pathological disorders. After four years, a new radiography was performed, where sign of peripheral bone formation and the absence of any pathological aspect or migration were observed. Considering the low complexity and morbidity of the technique, it becomes a good alternative to extraction, aiming to reduce the development of paresthesia in high-risk cases.
