Contact Angle Measurement and Wettability of TiO2 and ZrO2 Nano Composite Coated on cpTi

Abstract

Background: Dental implants have become one of the most reliable treatment options for replacing missing teeth due to their high success rates and long-term stability. Commercially pure titanium (cpTi) is widely used as an implant material because of its excellent biocompatibility, corrosion resistance, and its ability to achieve osseointegration with the surrounding bone. However, the biological performance of titanium implants is greatly influenced by surface characteristics such as surface roughness, surface energy, and wettability, which play an important role in protein adsorption, cell adhesion, and bone healing. Aim: The aim of this study was to evaluate the effect of a TiO2- ZrO2 nano-composite coating on the wettability of commercially pure titanium surfaces by measuring the contact angle. Materials and Methods: Commercially pure titanium discs were prepared and divided into two groups: a control group with uncoated titanium surfaces and an experimental group coated with TiO2- ZrO2 nano- composite. Surface wettability was evaluated using contact angle measurement by placing a droplet of distilled water on the surface and recording the angle using a goniometer. Results: The coated titanium surfaces showed a lower contact angle compared with the uncoated surfaces, indicating improved wettability and a more hydrophilic surface. Conclusion: TiO2- ZrO2 nano-composite coating enhances the wettability of titanium surfaces by reducing the contact angle, which may improve protein adsorption, cell attachment, and potentially enhance the osseointegration of dental implants.
