To evaluate the evolution of patients rehabilitated with endosseous implants after oral cancer treatment.
An observational retrospective study was carried out between 1991 and 2011 with a sample consisting of patients with oral cancer who had been referred for rehabilitation to the Prosthetics Rehabilitation Unit from the Oral and Maxillofacial Surgery Unit of the Virgen del Rocío University Hospital. All these patients have overcome oral cancer, and have a five-year follow-up after their oral rehabilitation. Age, sex, smoking habits, oral pathology, type of treatment of oral pathology, edentulism, receptor bone, prosthetic rehabilitation, timeouts, working time and evolution were studied. SPSS Statistics was used for statistical analysis of the variables studied. A chi-square test centered on the survival rate of implants placed in relation to the other recorded variables was performed.
17 patients were treated for cancer and rehabilitated with implant prosthetics, with a total of 106 implants placed. 32% were partially edentulous patients (4 patients), and 68.2% were completely edentulous patients (13 patients). An implant survival rate of 87.7% was observed at 5 years. In the upper maxilla, the survival rate was 79.2%, and in the mandible 93.7% ( = 0.03). 91 implants were placed in native receptor bones (85.8%), with only 15 implants placed in grafted receptor bone (14.2%). According to the type of receptor bone, in native receptor bones, 9 implants failed (90.1% of implant survival), while in grafted receptor bones, 4 implants failed (overall 73.3% implant survival rate) ( = 0.08).
Although a high survival rate was obtained in this study (with lower survival rates seen in mandible and grafted bone), prospective long-term studies are needed to assess the relationship between radiotherapy doses and the time required for implant placement, prosthetic protocol used, and type of implants used in patients selected for prosthetic rehabilitation.

评估口腔癌治疗后接受骨内种植体修复患者的病情发展情况。
1991年至2011年间开展了一项观察性回顾性研究，样本包括从罗西奥圣母大学医院口腔颌面外科转至修复重建科进行修复的口腔癌患者。所有这些患者均已战胜口腔癌，并在口腔修复后进行了为期五年的随访。研究了年龄、性别、吸烟习惯、口腔病理学、口腔病理学治疗类型、无牙情况、受体骨、修复性修复、超时情况、工作时间和病情发展情况。使用SPSS Statistics对所研究变量进行统计分析。针对所植入种植体的存活率与其他记录变量进行了卡方检验。
17例癌症患者接受治疗并采用种植体修复，共植入106枚种植体。32%为部分无牙患者（4例），68.2%为完全无牙患者（13例）。5年时观察到种植体存活率为87.7%。在上颌，存活率为79.2%，在下颌为93.7%（P = 0.03）。91枚种植体植入天然受体骨（85.8%），仅15枚种植体植入移植受体骨（14.2%）。根据受体骨类型，在天然受体骨中，9枚种植体失败（种植体存活率为90.1%），而在移植受体骨中，4枚种植体失败（总体种植体存活率为73.3%）（P = 0.08）。
尽管本研究获得了较高的存活率（下颌和移植骨中的存活率较低），但仍需要进行前瞻性长期研究，以评估放疗剂量与种植体植入所需时间、所采用的修复方案以及选择进行修复性修复患者所使用种植体类型之间的关系。牙种植体、口腔癌、存活率。
