Abstract
Osseodensification has been a subject of interest in the research arena. It employs densah bur, with negative rake angle and counterclockwise motion, to perform nonsubtractive drilling. In the presence of copious irrigation, it can push the bone trabeculae into the osteotomy instead of leaving it. This compaction can increase bone density, bone volume and subsequently enhance implant stability. The aim of this study is to report a case using densah bur successfully for osseous densification and crestal maxillary sinus augmentation. Further clinical trials are required to validate these findings and confirm whether it can be used for ridge expansion.

Techniques to improve bone height in the posterior maxilla have been introduced including maxillary sinus lift whether direct or indirect approach
Summary
Sufficient amount of pristine bone surrounding dental implants is perquisite for successful osseointegration. The direct approach is invasive with greater possibility of patient morbidity in contrast to the crestal approach The latter technique poses a 24% risk of sinus membrane perforation due to impaired visibility [2]. Another technique, adopting the concept of osseodensification, was introduced in 2014 and seems to be promising solution to the limitations of the techniques of enhancing bone quantity and quality. Densah bur was used for ridge expansion and crestal sinus lift in the left first premolar and second molar respectively. During insertion of Figure 4: Implant bed preparation in the second molar region along with crestal sinus lift.
