Introduction: The use of osseointegrated implants for the rehabilitation of patients with difficulty fitting conventional prostheses is becoming more frequent every day. A great eligible group for rehabilitation with this modality are patients treated for head and neck cancer (HNC). Irradiation in the region of HN may be limiting for implants, but there are evidences in the literature of techniques and planning favorable to the procedure in this group of patients. Less traumatic techniques for interventions in the oral cavity should be evaluated, and surgical guides for implant placement may be allies in these procedures. Case report: A 64-year-old female patient, treated with surgery, chemotherapy and radiotherapy in the oral cavity for a squamous cell carcinoma (SCC) in the tongue and, in a second moment, diagnosed and treated with surgery for SCC in the region of the left maxillary alveolar ridge by means of hemipalatectomy, needed rehabilitation with osseointegrated implants in the region where she had been primarily treated with radiation. The implant placement surgery was then planned and performed using guided technology so that minimal trauma to the oral structures could occur. Conclusion: The surgical procedure was successfully performed, and the patient is now waiting for the osseointegration period for posterior prosthetic rehabilitation.
