Abstract
This case report showed the proof-of-concept of a guided free gingival graft around a dental implant. A 65-year-old male presented to replace his 30 and 31. Once the osseointegration of the 2 implants placed by guided surgery has been achieved, a free gingival graft was indicated. The surgical planning of this graft was performed using the Cone Beam Computed Tomography and archs digital scanning already used for implant placement. The greater palatine foramen and gutter were radiologically located to protect their arterial content. Two surgical guides were designed, one for the palatal donor site and one for the recipient site. The first one will serve both as an incision guide and as a post-operative protective plate. The procedure was free of adverse events. At the 1-year recall, the average gain in keratinized tissue width amounted 2.5 mm. This guided surgery could be used in a patient with insufficient amount of keratinized tissue around a posterior implant. For the first time, it makes it possible to anticipate, accelerate and secure the intervention, to improve the practitioner's comfort and potentially the outcomes of free gingival grafts. Further research and clinical are needed to validate this protocol and to assess its long-term impact on peri-implant health.
