Functional Crown Lengthening with Osteotomy in Anterior Teeth as a Prevention Against Restoration Failure: A Case Report

Background: Teeth with inadequate clinical crowns lead to failure in restorative treatment. This condition complicates the tooth isolation in root canal treatment and results in minimal retention. Functional crown lengthening is the most common surgical procedure performed to increase the length of the clinical crown. Case Report: This case report discusses the functional crown lengthening along with osteotomy on the anterior teeth of a 25-five-year-old male patient with a chief complaint of loose crown denture on the upper left lateral incisor accompanied with soreness after root canal treatment. Area #22 was seen as a gingival excess with a clinical crown remaining <2 mm on intraoral examination and showed non-hermetic obturation on radiographic examination. Conclusion: The effectiveness of the treatment was proven by the nonrecurrence of gingival excess as seen from a one-month follow-up after functional crown lengthening.
