Other Resorbable Bioceramics

Calcium carbonate (CaCOs) in the form of coral skeletal (replaniform) replicas displays good resorption characteristics. The high porosity of the replica provides space for ingrowing bone cells. 

There have been several studies to evaluate the potential of calcium alumi-nates as functional bioceramics (Hulbert, Morrison and Klawitter, 1972). The advantages of this material include its compositional variability the different phases of which provide different rates of hydrolysis so that the overall resorption rate can be controlled. The release of Al ions in large concentrations into the

Dense and resorbable bioceramics The implant is replaced slowly by the bone. Belong to this group the tricalcium phosphate (TCP) and other phosphates as well as the calcium sulphate (CaS04V2H20 = plaster of Paris). 

Our researchers have worked very hard to accomplish our goals by doing things we felt would enhance our synthetic bone materials and their performance to enable them to equal and often exceed the performance of autograft as implants as well as in other types of bone augmentation and replacement. The nonporous tooth enamel solid calcium phosphate materials have flexural strengths of over 20,000 lb in.2 However, without pores it would take an extremely long time to resorb this nonporous bioceramic.
