Abstract

The invention relates to a titanium alloy for a dental implant, and belongs to the technical field of machining of titanium alloys. The titanium alloy for the dental implant is prepared from niobium and zirconium. The titanium alloy is high in biocompatibility and is extremely high in corrosion resistance, and is also excellent in mechanical performance; and moreover, the problems that an existingtitanium alloy for the dental implant is low in cellular adaptability and harm to a human body possibly occurs are solved.

Description

technical field [0001] The invention relates to a titanium alloy for dental implants, belonging to the technical field of titanium alloy processing. Background technique [0002] Titanium is an important structural metal developed in the 1950s. Titanium alloys have high strength, good corrosion resistance, and high heat resistance. In the 1950s and 1960s, high-temperature titanium alloys for aero-engines and structural titanium alloys for airframes were mainly developed. In the 1970s, a batch of corrosion-resistant titanium alloys were developed. Since the 1980s, corrosion-resistant titanium alloys and high-strength titanium alloys have been further developed. Titanium alloys are mainly used to make aircraft engine compressor components, followed by structural parts of rockets, missiles and high-speed aircraft. [0003] Titanium is non-toxic, light in weight, high in strength and has excellent biocompatibility. It is an ideal medical metal material and can be used as impla...
