Abstract: Maxillary sinus lift is commonly used to obtain sufficient bone height in the severely absorbed posterior area of maxilla. The traditional viewpoint is that osteotome sinus floor elevation (OSFE) cannot achieve promising outcome when residual bone height is less than 4 mm. To date, many studies using osteotome technique without grafting material in severely atrophic posterior maxilla have got promising outcomes. The aim of this review is to evaluate the possibility and the practicability of using osteotome-mediated sinus floor elevation without grafting materials when the residual bone height<4 mm

Key words: sinus floor augmentation, dental implant, alveolar bone height, bone graft
