Development of dental and medical systems for reconstruction of human body with high performance titanium materials

Calcium phosphate films on the surface of titanium have been investigated in order to apply them to the device for clinical treatments in oral and maxillofacial fields. The calcium phosphate films were coated on substrates by RF magnetron sputtering method. Commercially pure titanium (CP-Ti) plates were used as substrates. The films consisted of amorphous calcium phosphate and oxyapatite phases. The c-axis, (002), preferred orientation of oxyapatite phase was observed. The histological results demonstrated that the titanium plates coated with the calcium phosphate film were in close contact with bone at some parts of the interfaces between the bone and the implant, compared with non-coated titanium plates.
