When there is a significant deficiency in bone or soft tissue, ridge augmentation may be performed to restore the missing tissue(s).
Ridge augmentation may be done in conjunction with implant or restorative procedures.
Bone or soft tissue may be taken from one area of the mouth and transplanted to another, This is called an autogenous graft.
In the case of a block bone graft procedure, a piece of bone is harvested from a donor site and fixed into the recipient site using titanium screws. Once the block of bone is integrated, the fixation screws are removed and the implant or restorative treatment is completed. (Case 1)
An edentulous site may also be modified by expanding the bone that already exists at the site. This is called a ridge split. During this procedure, cuts are made in the bone and instruments are used to reshape and expand the bone. Graft may be placed into the space created after expansion, to fill the space and widen a ridge. (Case 2)
