group 1 with bioactive glass granules and no local antibiotics, while group 2 with calcium sulphate beads with a combination of local antibiotics: vancomycin and gentamycin. Special attention was taken to completely fill the defects with the bone substitutes. To prevent the biomaterial from being distributed outside the bone, a layer of bioglass in

The second material, calcium sulfate hemihydrate, is present in the form of a fine powder which, when mixed with water, chemically reacts to form calcium sulfate dihydrate, which exhibits particularly high mechanical resistance. Calcium sulfate hemihydrate occurs in two crystalline forms: alphahemihydrate and betahemihydrate.
