Indirect sinus lift in maxillary posterior region using BAOSFE technique

Abstract

Implant placement in edentulous posterior maxilla along the maxillary sinuses poses difficulties following tooth extraction due to ridge resorption and pneumatization of sinuses resulting in inadequate vertical bone height. The maxillary sinus lying close to the posterior maxillary edentulous ridge can be augmented by various methods such as lateral window sinus floor elevation, crestal approach, and grafting procedures. Summers introduced the less invasive approach for the sinus floor elevation known as osteotome sinus floor elevation technique in which the vertical bone height was attained by retaining and relocating existing bone using different graded osteotomes. He further modified this technique by addition of bone graft to the osteotomy site before sinus elevation known as bone added osteotome mediated sinus floor elevation (BAOSFE). This case report shows placement of implant in atrophic maxillary region using BAOSFE technique.
