20.500.12556/DiRROS-19028 Implant-prosthetic rehabilitation after radiation treatment in head and neck cancer patients a case-series report of outcome Background. Slovenia has a high burden of head and neck cancer. Patients are mostly treated with surgery followed by radiation therapy. Advanced surgical and prosthodontic techniques have expanded the rehabilitation options. The aim of the study was to review the outcome of implant-prosthetic treatment after radiation therapy. Patients and methods. Twenty irradiated head and neck cancer patients who received a removable implantsupported denture at the University Medical Centre Ljubljana were included in the study. Kaplan-Meier survival analysis, Cox proportional hazard models and logistic regression were used to assess the implant survival and success rate. Results. Twenty patients had 100 implants inserted. The estimated implant survival rate was 96% after 1 year and 87% after 5 years. Failures were mostly observed before loading (91.2%). Implants inserted in the transplanted bone were significantly more likely to fail. Out of 89 implants supporting the dentures, 79 implants (88.7%) were successful, meaning that they were functionally loaded and exhibited no pain, radiolucency or progressive bone loss. Prosthetic treatment was significantly less successful in older patients. The attachment system and the number of implants did not have a statistically significant influence on the success rate. Conclusions. Implant-supported dentures have been shown to be a reliable treatment modality after head and neck cancer surgery and radiation therapy. Possible early failures should be communicated with the patients. head and neck cancer radiation therapy dental implants rak glave in vratu obsevanje zobni vsadki true false true Association of Radiology and Oncology Ljubljana Angleški jezik Slovenski jezik by Authors Neznano 2024-06-03 09:15:36 2024-06-03 09:15:36 2024-06-04 03:38:29 0000-00-00 00:00:00 2017 0 0 Soavtorji: Jure Jamsek, Milan Kuhar, Natasa Ihan Hren, Andrej Kansky, Mutlu Ozcan, Peter Jevnikar; str. 94-100, IX no. 1 Vol. 51 Mar. 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2017-03-01 616-006 1318-2099 10.1515/raon-2016-0005 32924121 RAZ_Cotic_Jasna_2017.pdf RAZ_Cotic_Jasna_2017.pdf 1 BAD0CAD33121C0B73E75CBFC05FCE38A d944cd039661cb8a4fb50ed48a132596d901fd1734b4ff776f9edbcdd58a5b70 3df93d89-2179-11ef-9c9e-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=26113 Onkološki inštitut Ljubljana 0 0 0
