Different Coating Methods of Titanium Dioxide on Metal Substrates for Orthopedic and Dental Applications: A Review

Abstract

The outstanding physico-chemical characteristics to assist bone regeneration and cell development, titanium dioxide (TiO2) based materials have showed significant promise for applications in implants. Due to its excellent performance in a wide variety of applications, chemical stability, and inexpensive cost, this metal oxide has received the more attention. Coating techniques for creating surfaces made of this substance have been thoroughly investigated. The aim of this review article is to look at the current status of TiO2 technology for orthopedic and dental implants. Over the years, researchers have investigated several TiO2 coating deposition techniques on metal implants, with the goal of improving adhesion strength and long-term dependability. This review examines a variety of TiO2 deposition techniques on metal substrates in depth. Anodization, sol-gel method, plasma spray coating, cold spray coating, high velocity oxy-fuel spray, high velocity suspension flame spraying, pulsed laser deposition (PLD), ion beam deposition (IBD), magnetron sputtering deposition, electrophoretic deposition (EPD), electrochemical deposition and biomimetic deposition are among the methods examined.
