Influence of Different Zirconia Surface Treatments on Biofilm Formation (Biofilm2020)

University of Basel

Conditions: Surface Finish

Treatments: Other: Implant neck surface

Study type: Interventional

Funder types: Other

Details and patient eligibility

About

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.

Description:

The participants will carry an orthodontic device containing 4 discs of differently structured zirconia and titanium to test the biofilm formation in order to determine the ideal structure for the neck area of zirconia dental implants.

Treatment:

Other: Implant neck surface
