Ridge augmentation is necessary when there is inadequate bone for the placement of dental implants. Bone is harvested from another site in your mouth or donated bone may be used. The gums are temporarily separated from the bone at the site of the defect and the graft material is placed to augment the site. Screws, tacks, and membranes may also be utilized to stabilize the graft. As the bone heals there will be an increase in bone width and/or height allowing for future implant placement. Ridge augmentation usually requires 6 months of healing prior to implant placement.
