Ridge Preservation-extraction/Ridge Augmentation
When a tooth is removed or lost to gum disease, supportive bone is lost with it. Maintenance of bone is essential to support gum tissue for cosmetic restoration or allow for an environment that will support a dental implant. Careful management of the extraction site after tooth removal prevents unsightly bone loss and can provide a better cosmetic outcome for tooth replacement. At the time of tooth loss a bone graft is placed in the socket to promote bone healing and an ideal clinical outcome.

A ridge preservation/augmentation surgery can serve many purposes. It is most useful in preserving the natural appearance of the front of the mouth. It is also very instrumental in providing appropriate support for dentures or dental bridge construction. It can be essential in providing sufficient bone height to support dental implants. Periodontists recognize the role of ridge preservation in providing the support for more natural, appealing and functional tooth replacement.
The result can be very dramatic with this grafting technique.
