twenty recruited patients indicated for sinus augmentation and immediate implant placement will be divided into two groups (10 in each of the two groups), to compare bone formation and implant stability after shneiderian membrane elevation and augmentation with Hydroxyapatite Nano particles [Nanostreams] or augmentation with graft less tenting technique with simultaneous implant placement.

two cone beam CT will be taken for the patients, one immediate post operative and the other 6 months post-operative then the amount of bone gained or loss will be assessed by superimposing the same section in the two cone beam CT |
| 6 months post operative |
