Chemical Etching of Dental Implant Material

Abstract:

In this article we dealt with the development of a new method of chemical etching on dental implant materials, Grade 2 and Grade 5 titanium. Certain process creates reproducible homogenous and microrough surface, furthermore improves the reproducibility and productivity for industry appliance. During the research we modified the surface roughness of 2 mm thick samples in a single step of acid etching with a mixture of HF, HNO₃ and distilled water varying the etching time (15-600 seconds). After the surface treatment we obtained the changes of mass and the surface roughness on both sides of every sample. The resulting surface was examined with stereo-and electron microscopy. Based on our results we can determine a parameter setting where the homogenous and microrough surface is reproducible.
