The maxillary posterior edentulous region is the most challenging area in implant dentistry. Early loss of maxillary posterior dentition may result in sinus enlargement at the expense of the alveolus, as well as increased sinus pneumatization that decreases the amount of bone available in this area for implant placement. In order to create enough stability for an implant, new bone must be introduced in this area, and according to Misch, the posterior maxilla represents the most predictable area for synthetic bone grafting procedures1. In this paper, traditional and new, innovative sinus lift procedures for implant placement will be discussed. These techniques address the problem of the atrophic posterior maxilla. After a basic review of sinus anatomy, we will focus on two established and two recent surgical sinus lift procedures. The following four techniques will be discussed: the sinus lift surgical procedure using the Tatum approach, sinus floor elevation, one-stage maxillary sinus elevation using a bone core containing a preosseointegrated implant from the mandibular symphsis, and lastly, use of buccal fat pad in sinus grafting of a severely atrophic maxilla.
