Connective Tissue Graft for Gingival Recession in Mandibular Incisor Area: A Case Report

We report a case of gingival recession in the mandibular incisor region requiring a connective tissue graft. The patient was a 17-year-old girl who visited the Tokyo Dental College Chiba Hospital in 2014 with the chief complaint of gingival recession in the lower incisor region. She had received orthodontic treatment for 5 years and noticed the gingival recession on completion of active orthodontic treatment in 2013. Gingival recession in tooth #31 extended 3 mm beyond the muco-gingival junction (MGJ) and was clinically diagnosed as Miller Class II recession; probing depth was 6 mm. Following initial periodontal therapy, a connective tissue graft procedure was implemented. The connective tissue was harvested from the left palate. Healing was uneventful, and the grafted site showed a favorable outcome at 6 months postoperatively. We are continuing to carefully monitor the condition of periodontal tissue.
