Abstract

Aims: To conduct a systematic review on dental implant survival in autogenous bone grafts and flaps in head and neck (H&N) oncology patients.
Thereafter, to retrospectively report a service evaluation on implant- and prosthetic-outcomes of implant based oral rehabilitation in H&N oncology patients in a regional centre.

Method: For the systematic review, various databases were searched (01/1980-08/2017).
Retrospective analysis of implant- and prosthetic- outcomes of 167 patients treated within service from 2012-2017 was also undertaken, applying Kaplan-Meier survival curves and Cox proportional-hazards models.

Results: For the systematic review, 20 articles were reviewed, reporting on 1905 implants. Implant survival varied from 54-100%.
The service evaluation revealed implant survival estimates of 95.7% [95%CI 94.3-97.2%] at 3-years and 95.5% [95%CI 93.9-97.0%] at 5-years. Higher implant failure rates were shown in autogenous bone grafts/flaps in comparison to native bone (p=<0.001).
Fixed implant prostheses had a higher 5-year survival and 5-year complication-free survival, with fewer complications compared to removable implant prostheses.

Conclusion: The systematic review revealed implant survival in autogenous bone grafts in H&N oncology patients to be promising. The service evaluation supported the use of dental implants in the rehabilitation of H&N cancer patients, whilst demonstrating the risk of prosthetic failure and complications.
