Replacement of Bone where Teeth are Missing to Allow Dental Implants to be Placed or to Create Better Esthetics for a Bridge.
It is quite common for the bone to become narrow where teeth are missing, or where bone was thin around a recently extracted tooth, especially if a socket preservation procedure was not undertaken. A ridge augmentation involves the placement of bone particles or segments obtained from other sites in the mouth or from a bone bank under the gums to replace the bone that is missing or to create additional bone that is needed for a dental implant. In most cases a small dissolving membrane is used under the gums to hold the bone particles in place and give the bone time to heal. Not all sites are candidates for a ridge augmentation, but recent advances in techniques now allow many sites to be successfully augmented for implant placement.
