简要总结
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.

研究组 & 干预措施
Zirconia structure
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.
干预措施: Implant neck surface (Other)
结局指标
主要结局
Safranin Staining
时间窗: 3 months
The biofilm on the discs is quantified using safranin staining and evaluated with the measurement of optical density using a photospectrometer
次要结局
- SEM(3 months)
