What Researchers Did
Researchers conducted a retrospective study collecting data from 8 Japanese institutions on 19 patients who received Brånemark implants after maxillectomy.
What They Found
They found that out of 81 implants placed in 19 patients, 16 were lost, resulting in an implant survival rate of 80.2% over a mean follow-up of 27.6 months. No significant differences in survival were observed based on radiotherapy, chemotherapy, hyperbaric oxygen therapy, or prosthesis support system.
What This Means for Canadian Patients
Canadian patients undergoing maxillectomy and considering Brånemark implants can be informed of an approximate 80% implant survival rate based on this study. This information can help manage expectations regarding the long-term success of such prostheses.
Canadian Relevance
This study involved Japanese patients and institutions, therefore it has no direct Canadian connection.
Study Limitations
The study's small sample size of 19 patients across 8 institutions and its retrospective design limit the generalizability of its findings.
