Maxillary Sinus Augmentation by Autogenous Block Graft A- Case Report

Abstract

Tooth morbidity and tooth mortality are one of the most prevalent disease condition worldwide.When a tooth is lost, whether through dental decay, periodontal disease or dental trauma, the alveolar process begins to remodel. Continuous bone remodeling, absence of stimulation, loss of bone height, and density leads to an increase in antral pneumatization , leading to reduction in residual vertical bone height thus making standard implant placement difficult. To adapt, circumvent, and treat this limitation; maxillary sinus floor elevation is often done and has become an important preplacement procedure in dental implant treatment planning. In this article, we present a unique case of maxillary sinus augmentation of right posterior maxilla using a combination of autogenous chin block graft, and allograft with simultaneous placement of endosseous implants.

Implant Placement Following Crestal Sinus Lift with Sequential Drills and Osteotomes: Five Years after Final Loading Results from a Retrospective Study

“…In addition, the Schneider membrane can be approached through the alveolar bone crest [ 17 ]. This latter approach, named crestal approach to the sinus (or transcrestal approach), was first described by Summers in 1994 [ 18 ], and it is completely performed by osteotomes that allow the cortical bone to fracture and the sinus membrane lifting by means of gently grafting material pressure.…”
