ABSTRACT
PURPOSE:
This pilot study investigated the retrospective outcomes of implants placed immediately or with a delayed protocol in revascularized free fibula flaps (FFF). MATERIALS ANDMETHODS:
Patients undergoing FFF between 2014 and 2017 were included in the study. Implants were inserted either immediately or 23.63 ± 10.61 months after reconstructive surgery. Resonance frequency analyses were recorded at the time of implant placement (first control) and 4 months postoperatively while uncovering and screwing the gingiva formers (second control). The statistical significance level was set at P < .05.RESULTS:
Eight patients (four men, four women, mean age 46.75 ± 12.96 years) were included in the study. Twenty-six implants were placed in FFF (14 immediate, 12 delayed), and 28 were placed in the alveolus. All implant stability quotient (ISQ) scores were in high stability ranges. Statistically significant differences were observed between delayed (79.25 ± 4.77) and immediate implant placement (73.14 ± 7.42) at first controls, but not at second controls (79.17 ± 3.59 and 76.00 ± 6.18). The ISQ values of immediate implant placement significantly increased from first to second controls (P = .018). Bicortically placed implants showed significantly higher scores than unicortical implants (P < .05). ISQ values of FFF and alveolar bone groups were similar (P > .05).CONCLUSION:
High stability scores similar to alveolar bone could be achieved by both immediate and delayed implant placement. Bicortical implantation results in better implant stability.
