Relining the elevated Schneider's membrane with bone substitute

0.5cc of xenogeneic bone substitute without autologous bone is used as augmentation material.
BioOss: 0.25g/0.25mm-1mm
BioOss offers an excellent augmentation ossification/remodelling.

Place BioOss in a sterile dish, moisten with NaCl and insert with the periosteum elevator.  The BioOss particles are hydrophilic and can be transported well with the elevator. 
Distribute the bone substitute beneath the sinus mucosa with the finest, convex osteotome, vibrating at the same time.
Before screwing in the implant, remove the BioOss particles from the implant channel with an excavator.
