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.

shneiderian membrane elevation and augmentation with Hydroxyapatite Nano particles with simultaneous implant placement
shneiderian membrane elevation and augmentation with graft less tenting technique with simultaneous implant placement
patient satisfaction
evaluation of post operative complications in terms of pain and edema using patient pain chart
Time frame: 7 days post operative
implant stability
measurement of the implant stability using osstell device
Time frame: will be measured intra-operative after implant insertion and will be measured one more time 6 months after the first operation at the time of implant exposure
height of bone gain or loss around the implant
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
Time frame: 6 months post operative
