Following an extraction, the bone that supports the tooth resorbs and significantly reduces in volume. Taking into consideration the fact that extractions usually take place because the tooth can not be maintained, exhibits significant inflammation, a fracture of some sort of root resorption.
The extraction on its own, activates processes leading to loss of functional bone up to 50% within the first 6 months. Where there is pre-existing inflammation, this amount may be considerably greater.
A solution to this problem is to preserve the socket after an extraction. But many times can this process we had not even been proposed to the patient at the time of the extraction, or there may have been significant inflammation and the procedure could not be applied. Finally teeth could have been extracted many years ago and now we are faced with a significant resorption of the jaw.
In all these cases we can offer a solution by regenerating the jaw bone. This is achieved with the help of bone grafts. We can take grafts from the patient himself, which is then usually mixed with graft from another source – allograft or xenograft. These materials are placed in the bone defect and are covered with special membranes made of collagen or titanium mesh. In this way we can reconstruct the deficient bone and create ideal environment for the support of a long-term implant restoration.
