Dental implants are fixtures that serve as replacements for the root of the missing natural tooth and in the current day dental practice. Success or failure of the dental implant treatment is mainly based on the principles of osseointegration, which is the direct and stable anchorage of an implant due to the formation of bony tissue around the implant. A number of systemic and local factors influence the production of an osseointegrated interface and therefore the stability of the implant. Present article covers various methods used for surface treatment of titanium and titanium alloy implants. They are mechanical method such
asMachining,Grinding,Polishing and Grit blasting. Chemical treatment include Acid treatment,Hydrogen peroxide treatment,Alkali treatment.Sol–gel coatings include TiO2 coating,Calcium phosphate coatings, Titania/hydroxyapatite composite coatings and Silica coating.Electrochemical treatments includes Thermal spraying,Plasma spraying.Ion implantation and deposition include Oxygen implantation, Nitrogen implantation,Carbon implantation and deposition, Metal ion implantation. Surface modification methods used to improve the mechanical, chemical and biological properties of titanium and its alloys for biomedical application.
