Abstract

Bone replacing Ca–phosphate based materials with strong bioactive and osteoconductive properties are being used in many medical and dental applications as coating materials on implant surfaces and as scaffold for the regeneration of bone and dentin. It is possible to produce materials with enhanced biological or physico–chemical properties by doping different suitable ions into hydroxyapatite (HA) structure. Silicon (Si) is the most found element in Earth crust and has many effective properties in living bodies. The main aim of the present study is to supply the current knowledge about apatite materials which contain Si ions. After defining bone, the factors affecting new bone formation, osteoconductivity and osteoinductivity properties, the effect of Si doping into HA structure on osteoconductivite and osteoinductivite features will be mentioned.
