Abstract

Background: Although the need and significance of keratinized tissue around dental implants is a controversial issue, it is certain that the attached gingiva provides increased resistance of the periodontium to external injury, contributes to the stabilization of the gingival margin position and aids in the dissipation of physiological forces that are exerted by the muscular fibers of the alveolar mucosa on the gingival tissues. For many clinicians, a keratinized gingival band around implant restorations is routinely provided, in order to facilitate plaque control and hence reduce the incidence of plaque-related periimplant disease. Many surgical techniques have been utilized to augment gingival tissue dimensions.Aim/Hypothesis: The purpose of this poster is to present a clinical case where a free gingival graft was performed to increase the width of keratinized gingiva around two implants, as well as to display its 10 years follow-up examination.Material and methods: A female 56 years old was referred to our clinic for implant placement and tissue improvement. The maxillary left premolars were extracted, because of poor prognosis and it was decided to be rehabilitated with dental implants. Due to the fact that the amount of keratinized tissue over the edentulous ridge was minimal, a free gingival graft (FGG) was performed.Results: Results showed the presence of 3-4 mm of keratinized tissue around the healing abutments. Although some shrinkage has taken place, the 10-year follow-up examination of the patient demonstrated that the width of keratinized gingiva remains stable around both implants. Conclusion and clinical implications:In spite of the observation that the lack of keratinized tissue may not influence implant survival, the careful management of the amount of soft tissue around implants is considered essential, as it facilitates plaque control. The use of FGG for augmentation of keratinized tissue width has been reported to be a predictable and effective method with sufficient long term results.
