What is a ridge split?
After the loss of a tooth, the bone formerly around the tooth is resorbed – often leaving a very narrow ridge of bone. In order to place an implant, the ridge of bone is split as though it were a piece of corrugated cardboard being expanded to provide a wider space between each side. For the upper jaw, this is accomplished at the same time that the implant is placed; the lower jaw requires a second surgical visit approximately three weeks later.
