Background
The gingiva attached around the implanted periodontal can resist the invasion of bacterial root, improve the health condition of the implanted periodontal, and prevent bone resorption. Some patients have the condition that the implanted teeth are attached to the gum and the gum loss can reduce the width of the effective keratinized mucous membrane, aggravate the inflammatory reaction of the mucous membrane around the implanted teeth and increase the accumulation of bacterial plaque.
The missing or defective attached gingiva also results in alveolar bone resorption at the neck of the implant and loss of attachment capability, resulting in failure of the implant surgery. Therefore, it is necessary to take measures to increase the width of the attached gingiva around the implanted tooth. Currently, repair of defects is mainly addressed by free gum transplantation. The traditional widening surgery for implanting periodontal attached gingiva often fails due to the lack of good blood supply and the poor combination of skin flaps of the affected area.
