Grafting of the Maxillary Sinus With Intraorally Harvested Autogenous Bone Prior to Implant Placement

Patients with severely atrophic posterior maxillae and increased pneumatization of the maxillary sinus may lack adequate bone height for endosteal implant placement. Grafting of the maxillary sinus via a sinus lift procedure augments the atrophic ridge and allows for such implants. Grafting with bone harvested from intraoral sites has distinct advantages over other previously described techniques. Keywords: atrophic maxillae, autogenous graft, endosteal implants, sinus lift
