Physicochemical properties and biocompatibility of titanium and titanium alloy for dental restoration / 中国组织工程研究

ABSTRACT

Titanium is abundant, soft and widespread, moreover it costs lowly and contributes towards an excellent biocompatibility and causticity resistance. For the metal materials used for repairing human hard tissues, titanium is the most approach to the human hard tissues regarding elastic modulus. This result may relieve the mechanical inadaptability between metal implants and bone tissues. Compared to other alloys, titanium inlay or crown plays a role on the protection of dental pulp and the prevention of cold or hot stimulus. Titanium and titanium alloy are satisfactory with regrad to the physical, chemical and mechanical properties, especially the biocompatibility and elaboration. Those good characteristics lead to a wide application prospect of titaniun in the field of dental restoration. Titanium and titanium alloy have become a hot topic of the alloy study for the stomatology.
