Brief summary
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.
Interventions

Eligibility
Inclusion criteria
* Patients with atrophic maxilla and pneumatization of the maxillary sinus with residual bone height at least 5mm of residual ridge as per MISCH criteria * Both sexes
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| patient satisfaction | 7 days post operative | evaluation of post operative complications in terms of pain and edema using patient pain chart |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| implant stability | 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 | measurement of the implant stability using osstell device |
| height of bone gain or loss around the implant | 6 months post operative | 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 |
