Calcium sulfate(plaster of Paris) has been used in dental and orthopedic surgery for
about 100 years. It is well know that the plaster is, biocompatible, defect conformable
and moldable.
The purpose of this study is to evaluate two effects of calcium sulfate on bone
regeneration, that is the effects of graft materials and barrier for bone regeneration.
Cortical bone defects were formed for recipient site on the femurs of 19
Sprague-Dawley rats.The autogenous particulated one and calcium sulfate were grafted
to the defects,
Calcium sulfate paste, Gore-TexR membrane(W.L GORE &
ASSOCIATES LTD., U .S. A.) and rubber sheet were used for the shielding materials
The results were as follows :
1. Calcium sulfate that had been grafted in the cortical bone defect was almost
resorbed before bone remodeling, resultantly had little effect on bone regeneration.
2. Resoption process of calcium sulfate grafted on the bone grafting area tends to be
accelerated, as being divided into numerous small particles progressively.
Under the situation where the calcium sulfate was protected, with the coverage of
fascia, Gore-TexR membrane or rubber sheet, new bone formation was
confirmed with presence of calcium sulfate particles over 6 weeks after grafting.
3. In the case of calcium sulfate covered with membrane, distinct bone formation was
observe on the marrow space of femur adjacent to the plaster mass.
4. Rubber shielded plaster group revealed new bone trabeculae under the rubber sheet,
but it showed ischemis degeneration of superficial cortical bone.
