case_images: A 20-year-old female patient presented to the clinic following hemimaxillectomy owing to tumor excision accompanied with soft tissue approximation one year ago (Fig. 1A, B). Digital panorama and cone beam CT (Planmeca Pro Max, Finland) were acquired in order to evaluate the different rehabilitation options and identify the possibility of implant treatment (Fig. 1C, D).
case_images: A. An intraoral clinical photograph presenting the distribution of the Corticobasal  implants. B. A panoramic radiograph revealing the implant distribution: one implant in the midline nasal bone, one implant in the contralateral nasal floor, two pterygoid implants, and two ZDI  implants in the zygomatic bone. C. A 3D Cone beam CT showing the Corticobasal  implants distribution.

case_images: Implants were distributed as follows: one implant in the midline nasal bone, one implant in the contralateral nasal floor, two pterygoid implants, and 2 implants in the zygomatic bone (Fig. 2A). Postoperative panoramic and cone beam computed tomography views were captured to verify the implant's positions (Fig. 2B, C).
case_images: The prosthetic rehabilitation of the patient. A. An extraoral view of the final reconstructive prosthesis before insertion from the polishing surface. B. An extraoral view of the final reconstructive prosthesis before insertion from the fitting surface. C.

case_images: The occlusal was checked and occlusal adjustment was performed to eliminate any deflective occlusal contact (Fig. 3A, B and C).
case_images: The patient's follow-up after 3 years of follow-up A. An extraoral view of the patient. B. The intraoral view of the patient depicting his clinical presentation exhibiting optimal peri-implant oral health kindly notes the smooth surface of the implant without plaque adherence. C. A panoramic radiograph after 3 years of function. D. A 3D Cone beam CT showing the prosthesis after 3 years of function.
