Correction of midline diastema and severe gingival recession with periodontal surgery and orthodontic treatment: A case report with 20 years of follow-up

This case report describes the 20-year outcomes of multidisciplinary treatment in a patient with severe gingival recession, inadequate attached gingiva, and severe midline diastema. Following phase 1 periodontal treatment, mucogingival surgery was performed to create an adequate gingival area in a systematically healthy 20-year-old female patient, followed by orthodontic treatment 3 months postoperatively. The width of the keratinized gingiva increased, the gingival margin moved coronally, and the formation of a new papilla was successful. After 20 years, clinical improvement has remained steady.
