Bone grafts
An implant needs enough bone to be stable. When bone is lacking, it can be rebuilt before or during implant placement.
Why is bone missing?
After a tooth is lost, the bone that surrounded it gradually shrinks. An old infection, gum disease or long-term use of a removable denture make this loss worse. The 3D scan taken at the practice measures the available bone precisely.
Sinus lift
At the back of the upper jaw, the sinus is sometimes so close to the roots that too little bone height remains. The sinus membrane is gently lifted and the space created is filled with graft material. Depending on the remaining height, the implant is placed in the same session or a few months later.
Onlay graft
When the bone ridge is too thin or too low, a block of bone is fixed against it to increase its width or height. Once healed, the implant is placed in the rebuilt bone.
Ridge expansion
A slightly narrow ridge can be widened by gently spreading its two walls with fine instruments. This often allows the implant to be placed in the same session.
