简要总结
twenty recruited patients indicated for sinus augmentation and simultaneous implant placement will be divided into two groups (10 in each of the groups).to evaluate & compare bone formation & implant stability after shneiderian membrane elevation and augmentation with graft less tenting technique with different implant lengths.
group one will receive 8mm implant lenght while group two will receive 10mm implants.

结局指标
主要结局
height of gained bone
时间窗: 6 months post operative
two cone beam CT will be done for the patients, one immediate post operative \& the other 6 months post operative then the amount of gained bone will be assessed by superimposing the same section in the two cone beam CT.
次要结局
- implant stability(will be measured intra operative after implant insertion and will be measured once more 6 months post operative after the first operation at the time of implant exposure)
