Long term dental implant survival and bone level changes with special emphasis on radiation therapy after free fibula flap reconstruction - a retrospective study.

ABSTRACT:

Objectives

This study aimed to investigate the long-term survival of dental implants in patients after ablative resection of the maxilla or mandible and consecutive reconstruction with microvascular free fibula flaps (FFF).

Materials and methods

Patients treated with a FFF reconstruction of the mandible/maxilla and dental implant insertion were included. Implant survival and the influence of age, gender, radiotherapy, and localization were evaluated. Moreover, mesial and distal bone resorption was recorded. Implant survival was assessed using Kaplan-Meier methods and Cox regression, while bone loss was analyzed with linear mixed models. Multiple testing was adjusted by Scheffé's method; significance was set at p < 0.05.

Results

In total, 53 patients with 257 implants
