BLOCK BONE GRAFTING
When is it needed?
There are times when the bone defect size is too large for simultaneous guided bone regeneration (LINK). Conditions that will require an increased amount of bone to host a dental implant include the following;
- Areas where teeth were removed and not replaced
- An area where a tooth is missing and the nature of the disease associated with the tooth caused extensive bone destruction (i.e., infections).
- Areas of the jaw where permanent teeth were congenitally missing and as a result, normal tooth supporting bone failed to develop.
- Bone lost from dental trauma.
What does the procedure involve?
The procedure involves transferring a small block of bone from either the back of the mouth or at the front of the mouth to the future implant site. This is then secured with one or two tiny screws and overlaid with particulate bone (LINK) and a collagen membrane. The site is then securely closed and six months is usually given for the graft to fuse to the underlying jawbone before returning to the area to place an implant.
Once the graft is mature; the grafted bone will not only house an implant in “live” bone but it will also act to support the gum architecture in a manner that is both cosmetically pleasing and hygienically easy to maintain.
Bone grafting in the mouth today is a routine, predictable and painless procedure. It is done as a separate procedure before the implant is placed. The bone that has been transferred to the implant site will eventually grow back.
Is the procedure painful
Pain is surprisingly low. Some bruising and swelling is to be expected for a few days after the procedure.
