AI Technical Summary

Benefits of technology

This new type of material called Titanium (Ti), made up from tiny crystals that have been created through methods like chemical vapor deposition techniques, was found effective at promoting cell growth when placed into contact with tissues during medical procedures such as dental implants. It also improves its biocompatibility due to enhanced bonding properties for hard teeth compared to traditional materials. Additionally, there's some advantage if certain types of metal elements were added beforehand because they could help promote osteogenesis. Overall these improvements make Titanum better suited for use in medicine applications.

Problems solved by technology

This patented technical problem addressed in this patents relates to how to create an effective way to attach or grow tiny particles onto surfaces made from materials like titania without being laborious processes such as sand blastings and acids.

Abstract

The invention discloses a method for preparing a nano structure with biological activity on surface of pure titanium. The method for preparing the nano structure with the biological activity on the surface of pure titanium comprises the following steps: blasting sand, carrying out acid etching on the surface of the pure titanium, soaking in a preservation solution and carrying out ultraviolet irradiation. The prepared sand blasted and acid etched surface is soaked and preserved, compact nanoscale particles are automatically generated on the basis of the original micron-sized surface structure, then ultraviolet irradiation treatment is carried out, and the prepared sand blasted and acid etched surface has better biological activity and can serve as a bone nail and dental implant in orthopaedic department and stomatological department.
