Crestal approach maxillary sinus augmentation by osseodensification with simultaneous implant placement

Abstract

Primary implant stability at the time of implant insertion is a prerequisite to achieve osseointegration. Implant stability depends on the amount and quality available of bone tissue. The posterior maxilla is not considered the most favourable site for implant placement due to pneumatization of the sinus and low bone density. Osseodensification is a novel biomechanical bone preparation technique by use of specifically designed Densah burs™. This case report demonstrates simultaneous implant placement with sinus augmentation in the posterior maxilla with deficient bone height and compromised bone density in a patient undergoing implant therapy for replacement of missing maxillary right first molar. Implant osteotomy was prepared using the Densah burs and sinus membrane elevated using a viscoelastic putty graft material. Adequate sinus membrane lift along with enhanced bone density was achieved for the placement of standard-size implants using this technique.
