What Researchers Did
Researchers reviewed and combined data from past studies to see whether hyperbaric oxygen therapy helps dental implants survive in patients whose jaw area was previously treated with radiation.
What They Found
This systematic review and meta-analysis of 14 studies found a lower implant failure rate in patients who received hyperbaric oxygen therapy compared to those who did not. The implant failure rate was 9.21% in the hyperbaric oxygen group, versus 22.44% in the non-hyperbaric oxygen group. The search covered databases including PubMed, Google Scholar, and the Cochrane Oral Health Group Trials Register, and started with 62 titles narrowed down to 14 included articles. Results were pooled using a random-effects meta-analysis model.
What This Means for Canadian Patients
For Canadian patients who have had radiation therapy to the jaw area and need dental implants, this review suggests hyperbaric oxygen therapy is linked to fewer implant failures compared to not using it. This applies specifically to irradiated maxillofacial patients undergoing prosthodontic rehabilitation, not to dental implants in general.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
The meta-analysis pooled different study types, including randomized controlled trials, prospective and retrospective studies, and preliminary reports, which vary in design quality and can affect how reliable the combined result is.
