Influence of Different Zirconia Surface Treatments on Biofilm Formation

Switzerland16 participantsStarted 2020-01-01

Plain-language summary

The aim is to test the influence of surface finish on biofilm formation on the transmucosal part of zirconia implants in an in vivo study. Sixteen test person will therefore receive an orthodontic apparatus containing the specimens with the respective surfaces and carry them for 2x 24h. The primary outcome is the spectormetrical quantification (OD value) of biofilm on the specimens that have been carried by the test person over 24h. Biofilm will be analysed using scanning electron microscopy.
