Partial and subtotal maxillectomies are frequently indicated as surgical procedures for hard palate cancer, often with defects of the alveolar ridge. Here, we report a case of hard palate cancer treated from the nasal cavity side by tumor resection using Le Fort I osteotomy. Furthermore, bilateral maxillary sinus floor elevation was performed to achieve good results by implanting a dental implant. The patient was a 64-year-old man, who had become aware of pain in the palatal region while eating and underwent a biopsy in November 2015, resulting in the diagnosis of squamous cell carcinoma (SCC). He underwent tumor resection approaching from the nasal cavity side with Le Fort I osteotomy in January 2016 for the diagnosis of hard palate cancer. Maxillary sinus floor elevation was performed in July 2019 using an implant-retained obturator prosthesis, and implant surgery was performed in May 2020. Four implants of bilateral maxillary molars obtained sufficient initial fixation with buried torques of 30 to 35 Ncm. Healing abutments were mounted half a year after the primary implantation surgery. As of 2021, fixation has been uneventful.
