| Research Abstract |
The purpose of the present study was to evaluate the clinical usefulness of bone substitutes such as tri-calciumphoshate (B-TCP), hydroxyapatite (HA) and mixed bone material (B-TCP+HA) for bone grafting and sinus augmentation on oral and maxillofacial bone. The results of assessment of bone grafting on the limited bone volume owing to atrophy of the alveolar ridge and bone loss of postextraction was as follows. 1) excellent : 10 cases 2) good : 4 cases 3) poor : 4 cases 4) very poor : 1 case. In this "very poor case", the bone substitute block made by B-TCP+HA was removed because of bone infection after dental implant placement. The authors concluded that combined grafting with bone substitutes using the autogenous and B-TCP+HA granulation seems to be effective as a bone material against bone augmentation.
