Objective: To analyse the short-term clinical results of the effect of apically repositioned flap combined with free gingival graft to widen keratinized tissue in implant area, so as to provide a basis for its clinical application.
Methods: Fifteen patients with intraoral single or multiple missing teeth, who did not undergo implant restoration or who re-examined after implant restoration completed were included, along with KW less than 1-2 mm on the buccal side of the median line of the alveolar ridge crest in the implant area, or KW less than 1-2 mm on the buccal side of the abutments and dental crown margins. All underwent apically repositioned flap combined with free gingival graft, which were reviewed.
Results: Fifteen patients with missing keratinized gingivae underwent free gingival flap graft, survived with all grafted gingival flaps. Compared with before implantation, significant keratinized tissue widening and area gain were obtained at 1 and 3 months postoperatively.
Conclusion: The free gingival flap graft can significantly widen the buccal keratinized mucosa of the implant, and to some extent maintains the health status of the implant, which is worthy of clinical promotion and application.
