Block bone graft (iliac crest bone graft)
The iliac crest is the curved ridge at the top of the pelvic bone.The iliac crest is a particularly important bone structure in medicine, as it contains large amounts of bone marrow.
The large amount of bone that makes up the iliac bone crest is also sometimes used as a source for bone grafts. It can provide, for example, sufficient volumes of bone for many types of facial reconstruction surgery. The iliac crest posterior region, at the back of the hip, provides particularly large volumes of bone.
CLINICAL CASE
Surgeon: DDS, MDS Vo Van Nhan
Patient: a 50 year old man patient, healthy was in good and smoker. The missing teeth on upper jaw had been absent for 10 years therefore, the alveolar process showed a marked lateral deficiency because of horizontal bone resorption.
 |
almost of teeth was losed
|
 |
| The radiographic showed bone loss |
CT cone beam was taken to evaluate jaw bone density exactly.
 |
CT cone beam showed the anterior area in three- dimension severe bone loss

Treatment plan
- 6 implants on upper jaw
- 2 mini implants to support temporary teeth
- Block bone graft and sinus lift
- The time to finish treatment plan is about 6 months
Because the anterior area has severe bone loss, implants will be placed into the back side. In this particular case, the volume of the maxillary sinus enlarge so grafting on the maxillary sinus floor incerases the vertical height of the posterior maxillary bone prior to implant placement.
The volume of the maxillary sinus is large so bone graft procedure was performed with autogenous bone material which harvested from iliac crest.
