Due to the small amount of bone remaining and extensive fibrous tissue in the palate region, rehabilitation with conventional implants associated with zygomatic implants was chosen instead of subjecting the patient to a reconstruction with large bone grafts (Figure 1(a)). For the preoperative evaluation, panoramic radiography and cone-beam computed tomography of the maxilla and zygomas were requested, which confirmed the low bone availability in this case (Figures 1(b) and 1(c)).
(a) Panoramic tomography and (b) tomographic image of the patient after 2 years of follow-up. Note the good position of the implants placed and the absence of complications.

During the postoperative period, radiographic and clinical examinations showed that there were no complications (Figures 2(a) and 2(b)).
(a) Postoperative clinical condition of the patient with the upper protocol-type prosthesis in function, (b) postoperative condition of the prosthesis, and (c) postoperative condition of the palate. Note the good clinical outcome of the upper protocol-type prosthesis after 2 years of follow-up. Furthermore, a good condition of the palate with the communication of the nasal and oral cavities is showed.
