A detailed analysis of titanium implants lost in irradiated tissues

Prosthodontic rehabilitation of oral function in head–neck cancer patients with dental implants placed simultaneously during ablative tumour surgery: an assessment of treatment outcomes and quality of life

“…Other disadvantages include the risk of interference with or delay of the oncological therapy, including radiation therapy, and the development of post-treatment complications caused by implantation being performed during ablative surgery 17 . These disadvantages are assessed to be of minor importance because of the very low incidence, especially when compared to the high risk of harmful tissue reactions in the case of implantation after radiotherapy 5 . In addition, a two-stage technique is advocated to minimize the risk of early post-ablative complications as the implants are covered by mucosa during radiation therapy.…”

Implications of radiation dosimetry of the mandible in patients with carcinomas of the oral cavity and nasopharynx treated with intensity modulated radiation therapy

“…It has been shown that higher osseointegrated implant loss rates are associated with prior radiotherapy 9 . This increased failure rate of osseointegrated implants has been correlated with higher radiation dose, time since administration of radiotherapy, and site of implant installation 11 .…”

Implant-retained nasal prosthesis for reconstruction of large rhinectomy defects: the Salisbury experience

“…Radiotherapy is often used in the treatment of nasal cancers and is known to be associated with increased frequency of implant failure [1][2][3]5,[9][10][11][12]14,18,24 . In the present study, implant failure was more common in patients who had radiotherapy (14%).…”

“…In the present study, implant failure was more common in patients who had radiotherapy (14%). The use of hyperbaric oxygen to improve the success rate of implants placed within the radiotherapy field is controversial 3,5,[9][10][11][12] . In this study almost all patients who had radiotherapy also had hyperbaric oxygen, which would explain the similar success rates in the two groups (radiotherapy (14%) and radiotherapy plus hyperbaric oxygen (16%)).…”

“…A literature review documented 128 implants placed in the nasal skeleton to retain nasal prostheses of which 23 were placed within a field of radiotherapy. The success rates were 60-100% in patients who had not received radiotherapy and 50-100% in patients who had received radiotherapy 1,3,8,[11][12][13][14][15]17,22,24 . Little information is available on the technical aspects of the procedure or the factors influencing the success of these implants and the retained prosthesis.…”
