Maxillary Sinus Augmentation for Dental Implants

Abstract

Pneumatization of the maxillary sinus secondary to posterior maxillary tooth loss is an extremely common finding. Significant atrophy of the maxilla prevents dental implant placement in this region. Grafting the floor of the maxillary sinus has emerged as the most common surgical modality for correcting this inadequacy. Graft material is introduced into the space created inferior to the sinus membrane. Various grafting materials and techniuqes might be used in this procedure. The aim of this article is to review the essentials of maxillary sinus augmentation, to clarify this procedure for otolaryngologists, explain its function, and describe the augmentation materials, techniques and complications.
