Sažetak
Calcium sulfate (CaS) based materials are frequently used as dental implants. CaS is higly biocompatible material and does not interfere with healing process. In the use, there are two modifications, calcium sulfate dihydrate (CSDH) and calcium sulfate hemihydrate (CSHH). Before the implementation all implants, does not matter of the origin, need to be sterilized and it is usually done with X or gamma irradiation. Unfortunately, the research of irradiation on the implants based on phosphates are scarce, but for sulfates are not to be find. Briefly it should provoke the formation and stabilization of radicals. That is why the structures of CSDH and CSHH as well as commercial material Bond bone, which is the mixture of both, are investigated before and after the gamma irradiation with electron paramagnetic resonance (EPR) spectroscopy, thermogravimetry (TG) and Fourier transform infrared spectroscopy (FTIR). The results have shown that EPR spectroscopy is a method which can be used to improve the quality control of bone graft materials after syntering, processing and sterilization procedure.
