Gingival carcinoma is a common malignant tumor occurring in the anterior area of the mandible, which can be derived from the epithelium of gingival mucosa. Surgical extended resection is the main treatment of gingival cancer, which can lead to anterior mandibular defect including mouth floor and mandible and mucosa of lower lip. According to the size of the defect, the common repair method is free musculocutaneous flap with vascular pedicle or pedicle flap. We present a method of repairing mandibular anterior tooth defect with an island flap pedicled with the mental artery.
