Schnederian Membrane Elevation and Augmentation With Deproteinized Bovine Bone [Tutu-gen Bone] Versus Graft Less Tenting Technique With Simultaneous Implant Placement

Cairo University30 enrolled

Overview

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.

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)

Outcomes

Primary Outcomes

patient satisfaction

evaluation of post operative complications in terms of pain and edema using patient pain chart

Time frame: 7 days post operative

Secondary Outcomes

implant stability

measurement of the implant stability using the osstell device

Time frame: 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

height of bone gained or lost around the implants

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.

Time frame: 6 months postoperative
