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.

The biofilm formation is tested on discs manufactured of zirconia with different surfaces in vivo using orthodontic devices that the participants carry over 24h
University Center for Dental Medicine Basel
Basel, Canton of Basel-City, Switzerland
Safranin Staining
The biofilm on the discs is quantified using safranin staining and evaluated with the measurement of optical density using a photospectrometer
Time frame: 3 months
SEM
The morphology of the biofilm is analyzed using scanning electron microscopy
Time frame: 3 months
