Case Details
A patient lacks the necessary bone to support dental implants in the upper left quadrant and therefore requires a bone augmentation procedure. A bone bone block graft is harvested from the patient’s lower jaw (donor site) and 2 bone shields (aka bone shells, bone veneers or bone plates) are created from it. In addition, Bone chips and bone particulate are harvested from the patient as well and are all placed into the upper left quadrant (recipient site) along with growth factors. After extracting a hopeless tooth and another tooth with root tip fragments, a vertical augmentation of the ridge is implemented by placing and fixating the 1st bone shield at the desired height for the desired new bone growth. The 2nd bone shield is placed and fixated sideways to provide a protective barrier for the autogenous bone graft during the healing phase. The area is then allowed to heal for a minimum of 3 months before the dental implants are placed.

Description: A tunnel technique is utilized where there will be no flaps created. Only from this one incision is where the recipient site for the bone is prepared and all of the contents will be inserted. This method will increase the overall success of the split bone block (SBB) technique.
