Surface energy analysis of dental Implants after plasma activation with the piezobrush PZ3, using the picolitre dosing system PDDS

Wettability is of major importance for all kinds of surface treatments. To gain a deeper understanding of the wettability difference between the original and treated dental implant surfaces, contact angle measurements and a surface energy analysis were done using water and diiodomethane as the test liquids.

The optical contact angle measuring and contour analysis system OCA 200 in combination with the picolitre dosing system PDDS from DataPhysics provides a simple and reliable method to determine the surface energy of dental implants before and after surface treatment with a piezobrush PZ3.

The used measuring system can be employed to study the surface energy of all kinds of micro-structured samples, which is of increasing importance for improving industrial treatments like painting, cleaning, coating or conglutination.
