Abstract
Implant surgery for an edentulous maxilla with severe resorption is challenging for clinicians, necessitating various preoperative considerations. This report demonstrates a case of implant placement for restoring an edentulous maxilla using guided bone regeneration and bilateral sinus lift surgery in a 47-year-old man with chronic rhinosinusitis. Prior to the surgical procedure, the patient had taken an antibiotic and a bronchodilator for 6 weeks after consulting with an otolaryngologist to minimize the risk of postoperative complications and implant failure. Seven implants were placed in the augmented maxillary anterior and posterior alveolar bones and were maintained without any complications. Meticulous preoperative evaluations increase the success rate of dental implantation, particularly in cases requiring invasive surgical procedures.
