Major & Minor Bone Grafting
The most common indication for Bone Grafting is prior to dental implant placement dental. This is due to the atrophy (bone loss) that occurs as a result of the loss of teeth over time; this will require the creation of a more solid bone base to support the implant.
WHAT IS BONE GRAFTING?
It is a surgical procedure that uses bone mineral to replace missing bone.
Source of the bone graft. Bone from the chin area, ascending ramus area of the lower jaw, leg or hip of the same individual receiving the graft (Autograft), bone bank cadavers (Allograft) or synthetic bone substitutes (Xenograft). Grafts used are bioresorbable and do not react while acting as a reservoir of necessary minerals inducing the formation of new bone.
Conditions that may precipitate this procedure include tooth extraction, trauma, infection, periodontal diseases, and congenital defects.
MAJOR BONE GRAFTING
A major procedure done for severe bone degeneration takes several months for the transplanted bone to grow enough new bone for implant support. The surgery is usually done in the operating theatre and requires patient admission into the hospital ward.
MINOR BONE GRAFTING
A minor procedure can generally be done at the same time as the implant surgery or under local anesthesia in the office. Examples include ridge preservation, onlay bone grafting, and sinus lift procedures.
