---|---|
Active Comparator: With primary closure
The ridge augmentation graft will be covered with a barrier membrane and the soft tissue will be primarily closed.
|
Procedure: With primary closure
A cancellous block allograft will be placed for ridge augmentation and covered with a barrier membrane. The soft tissue will be primarily closed over the membrane.
Other Name: Primary soft tissue closure over the membrane.
|
Experimental: Without primary closure
The ridge augmentation graft will be covered with a barrier membrane and the soft tissue will not be primarily closed.
|
Procedure: Without primary closure
A cancellous block allograft will be placed for ridge augmentation and covered with a barrier membrane. The soft tissue will not be primarily closed over the membrane.
Other Name: No primary soft tissue closure over the membrane.
