Clinical outcomes and periodontal conditions of dental implants placed in free fibula flaps (FFF): a retrospective study with a mean follow-up of 6 years

ObjectivesUp-to-date literature regarding long-term success of implant rehabilitations after microvascular reconstructions with free fibula flap (FFF) is still very scarce. This study aimed to evaluate clinical outcomes, especially related to oral hygiene conditions, of patients rehabilitated with this technique.Materials and methodsA total of 25 patients who underwent maxillofacial reconstructive surgery with FFF were retrospectively evaluated for soft tissues conditions, oral hygiene habits, and implant survival and success, assessed with a mean follow-up of 6 (range 2-15) years after loading.ResultsFourteen patients received full-arch fixed prostheses and 11 removable bar-supported overdentures. At the follow-up evaluation, 52% of prostheses did not allow proper accessibility for oral hygiene. Overall prosthetic survival was 100%, and implant survival and success were respectively 93.6% and 72%. Prevalence of peri-implantitis was 29% at implant level and that at patient level 96%.ConclusionsSix-year clinical outcomes of this study reveal that poor oral hygiene practices and compliance by patients who underwent maxillofacial reconstruction with FFF are significantly associated with peri-implant disease.Clinical relevanceFindings of the present study underline the need by clinicians for a careful assessment, in reference to a specific implant therapy, of patient's prosthetic accessibility for oral hygiene procedures.
