Maxillary Sinus Floor Elevation
Conditions
Keywords
tenting, grafting, implant placement
Brief summary
30 recruited patients indicated for sinus membrane elevation with simultaneous implant placement. patients are divided into 2 groups each group contain 15 patients, one group assigned for placement of bovine bone graft after membrane elevation and insertion of the implants while the other group assigned for graft-less tenting technique after membrane elevation and insertion of the implant.
Detailed description
On the 2 groups a mucoperiosteal flap is elvated then a lateral wondow is created then sinus membrane is elevated then the implants are placed, in the control group deproteinized bovine bone graft substitute is placed in the sinus for augmentation while in the study group no bone graft is added inside the sinus( graftless tenting technique)
Interventions
PROCEDUREsinus lift,implant placement,tenting
elevation of the sinus membrane then insertion of the implants without any bone graft material( graft-less) for augmentation
PROCEDUREsinus lift,implant placement,bovine bone
sinus membrane elevation then placement of the implants together with deproteinized bovine bone substitute as a graft material for augmentation

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 intraoperatively immediately after insertion of the implants and will be measure one more time 6 months after the 1st operation at the time of exposure of the implants | measurement of the implant stability using the osstell device |
| height of bone gained or lost around the implants | 6 months postoperative | two cone beam computed tomography(CBCT) will be taken for the patient, one immediate postoperative and the other 6 months after the operation then the height of bone gained or lost around the implants will be assessed by superimposing the same section in the two CBCTS. |
