CONE BEAM COMPUTED TOMOGRAPHY AND ODONTOGENIC SINUS DISEASE IN RISK STRATIFICATION OF POSTERIOR MAXILLARY SINUS FLOOR ELEVATION COMPLICATIONS

Abstract

Sinus floor elevation remains a routine method for implant rehabilitation in the posterior maxilla when residual bone height is inadequate. Its safety, however, depends not only on surgical technique but also on rigorous preoperative assessment. This extended abstract summarizes contemporary evidence on complications of sinus floor elevation, with emphasis on the diagnostic role of cone beam computed tomography and the need to identify odontogenic maxillary sinus disease before augmentation. The source material was a focused narrative review of publications indexed in major medical databases between 2003 and 2025. The most frequent intraoperative complication is perforation of the Schneiderian membrane, and its probability increases in the presence of sinus septa, unfavorable sinus configuration, and radiological evidence of inflammatory or structural abnormalities [1-4]. Postoperative complications include sinusitis, graft contamination, wound problems, and migration of implants or biomaterials into the sinus cavity. The evidence supports one central practical conclusion: cone beam computed tomography should be treated as the principal tool for risk stratification, and sinus floor elevation should be postponed when unresolved odontogenic infection or clinically significant sinus disease is suspected [2,5,6].
