Bone grafting techniques are used in cases where we wish to place a dental implant but do not have enough volume of natural bone in the site in which to place an implant directly in to. Grafting usually involves using demineralised freeze-dried bovine (cow) bone held in situ using either a porcine (pig) collagen membrane or polytetrafluoriethylene (PTFE) membrane. For larger grafts the bovine bone is mixed with some of the patients bone collected from the local area. The grafts are either performed 6 to 9 months prior to dental implant placement or at the same time as dental implant placement depending on the initial morphology of bone in the area. Dr Mallorie has been performing bone grafting procedures for over 10 years and is highly competent and predictably regenerating bone to facilitate appropriate implant placement.
