Patient: A 74-year-old man in his seventies complained of missing anterior crowns, poor appearance, and difficulty in pronunciation and eating. Significant structure loss of the maxillary left central incisor had reached the subgingival region. Crown lengthening was performed as a preprosthetic treatment, followed by restoration.
Discussion: Crown lengthening was performed to get a ferrule effect and to recover supracrestal tissue attachment, taking into account the crown-root ratio. As a result, the remaining tooth structure could be fully used.
Conclusion: This case report describes the favorable clinical outcome of a patient with significant structure loss of the maxillary incisors by getting a ferrule effect to fully use the remaining tooth structure.
