Abstract
Statement of problem
Implant-retained prosthodontic rehabilitation of patients with head and neck cancer
is complex. However, the extent of prosthodontic complications has been sparsely reported
within the literature.
Purpose
The purpose of this retrospective study was to describe the range of complications
and issues that affected the oral rehabilitation treatment of patients with head and
neck cancer who had completed implant-retained prosthodontic rehabilitation in a tertiary
treatment center.
Material and methods
A retrospective analysis of complications and their consequences in patients treated
in a regional unit from 2012 to 2017 was performed. Descriptive analysis was carried
out on the type and frequency of complications and their consequences for the patients’
treatment. Complications were grouped into the following complication types: local
and systemic, implant, peri-implant soft tissue, and clinical prosthodontic complications.
Implant success and implant survival were also reported.
Results
The sample was composed of 163 patients with head and neck cancer who had completed
implant-retained prosthodontic rehabilitation. Local and systemic complications affected
8.6% of patients, and peri-implant soft-tissue complications affected 9.8% of patients.
Clinical prosthodontic complications leading to repeated clinical or laboratory stages
occurred on 48 occasions in 45 patients (27.6% of patients). A total of 763 implants
were placed. Implant survival was 95.8% and implant success 94.5%, with a mean follow-up
of 42.1 months.
Conclusions
This retrospective evaluation indicated that complications arising during the process
of implant-retained prosthetic rehabilitation in this patient group were variable
and common. Such complications can delay the process of treatment and lead to repeating
or restarting clinical and laboratory stages of treatment.
