The maxillary posterior region is often a problem area concerning the placement of dental implants. The maxillary sinus poor augmentation (sinus lift) is useful method for patients who have a limited amount of bone volume in the edentulous posterior maxilla. One patient, a 33-year-old female, complained about prosthetic treatment by implant because of an edentulous bilateral posterior maxilla, and a prominent malar eminence. In a preoperative panoramic x-ray photograph, the bilateral posterior maxillary alveolar bone was shown to be advanced in vertical resorption, and a thickening of mucosa in the bilateral maxillary sinus poor was apparent. We performed alveolar ridge augmentation using the zygomatic crest and rami of the bilateral mandibular bone. The diameter of zygomatic arch was retrenched to about 5mm. The zygomatic bone was very compact as well as the ramus of the mandibular bone. We concluded that the zygomatic crest was a useful donorsite for alveolar ridge augmentation.
