Current research projects of PD Dr. Sönke Harder 

Assessment of pyrogenic contamination of titanium and zirconia dental implants with a human whole blood assay in vitro.

The aim of this research is to better understand the immunological response of the human body to dental implants and to improve the success rates of implants.

Bacterial diversity of dental intra-implant contamination.

If a dental prosthesis consists of two parts, germs and biofilm may form inside the dental prosthesis. The aim of the research is to explore the causes and consequences of this biofilm.

Influence of chewing force, thermal cycling and storage time on the retrievability of cemented implant retained crowns 

This study examines which kind of mouth-related influences lead to an aging of implant cements and which cements are most suitable to fix cemented implant-borne dental prosthesis.

Effect of remineralizating solution on hybrid layer of resin bonded etching dentin in vitro.

This study examines how fillings of teeth can last for a longer time.

Adhesive bonding of Titanium alloy: Development of a new ready-made tapered telescopic crown abutment

This study clarifies which cells adhere best on which material of implant abutments.

Comparison of a computer-based registration system with a central support pin registration.

This is about the determination of the relation between the jaws and which of the two methods is more precise. 

Influence of abutment materials and the cement of bipartite abutments on the cervical implant bone and the soft tissue adhesion.

Here it is explored with which material the implant abutment can best preserve the tissue surrounding the implant (bones and gums).
