Surface Properties of Different Heat Treated Titanium Alloy Dental Implants

Titanium alloy surface properties have an essential role in the interaction of dental implants with bone, and alteration of the surface of the implant could improve osseointegration. This study was designed to investigate the effect of different heat treatment temperatures on titanium alloy surface properties for dental implants. The effect of different temperatures of heat treatment (750C, 850C, 950C and 1050C) were investigated on the surface topography, surface chemistry, titanium oxide layer thickness, blood contact angle,& blood drop diameter of titanium alloy. The disks were prepared from titanium alloy (Ti-6Al-4V) and the samples were divided into five groups depending on the different temperatures of heat treatment. The heat treatment at 1050 C for 30 minutes significantly enhanced the titanium alloy surface characteristics, surface topography, titanium oxide layer thickness, surface chemistry, blood contact angle, and blood drop diameter. This may result in faster and stronger bone formation around dental implants.
