Scientific Projects

Not only do our dentists offer compassionate, friendly and reliable dental care but they are also pioneering in innovative dental scientific research and technology.

We believe in being at the forefront of the industry so that we can use the latest knowledge, techniques and technology to provide the very best results to our patients. As such our dentists, Dr. Harder and Prof. Mehl, are regularly engaged in scientific research projects and are internationally renowned for their expertise and experience.

Below are just several of the current scientific projects that they are working on:

Prof Mehl’s current projects

Influence of membrane specifications and longevity and bone growth

This study evaluates the influence of membrane stability on bone growth during augmentations in the animal model. The aim of this study is to investigate what influence the resorption time of the membrane has on new bone formation.

Can buccal defects be managed for immediate implantations

To the knowledge of the authors, there is no study that investigates new bone formation after immediate implantation in the absence of a buccal lamella. If it turns out that bone and soft tissue healing is independent of open or closed implant healing, many patients could be spared a second or even third surgical procedure. The aim of this study is to evaluate the influence of open or closed healing in the absence of a buccal bone lamella on new bone formation.

Influence of buccal defects in immediate implantations on the soft tissue

The aim of this study is to evaluate the influence of open or closed healing in the absence of a buccal bone lamella on soft tissue anatonia. Together with Part I of this study, a valuable explanation for the development of the causes and prevention of peri-implant soft and hard tissue losses could be provided and patients could possibly be spared surgical interventions.

BMP-2 plasmid DNA-loaded chitosan films – a new strategy for bone engineering & Enhancing bone regeneration by combining mesenchymal stem cell sheets with β-TCP / COL-I scaffolds.

These studies, which are carried out in cooperation with the University of Zhejiang, Hangzhou, China, focus on improving bone growth in bone structures with the help of stem cells and / or bone proteins.

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

This study examines which mouth-related influences cause implant cements to age and which cements are best suited for cementing implant-supported dentures.

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

This study looks at how fillings in teeth could last longer.

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

This study tries to investigate how best to bond titanium abutments of implants.

Frontiers in Implantology – cell adhesion on different abutment materials

This study aims to clarify which cells adhere best to which implant build-up material.

Comparison of a computerised registration system with the central support pin registry

This is about determining the relationship between the jaws and which of the two methods is more accurate.

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

The material with which the implant abutment can best preserve the tissue surrounding the implant (bones and gums) is examined here.

Dr Harder’s current projects

In vitro investigation on the sealing behaviour of the implant-abutment interface – Zirconia vs. Titanium implants.

The aim of this investigation is to test the tightness of two-part ceramic implants against bacterial colonisation.

Change of proinflammatory gene expression in human whole blood after contact with UV-conditioned implant surfaces.

The aim of this study is to better understand the body’s immunological response to dental implants and to improve the success rates of implants.

Investigation on the influence of storage time on the cell efficacy of plasma-conditioned titanium implant surfaces on human osteoblasts in vitro.

In vitro investigation of changes in proinflammatory gene expression in human whole blood after contact with plasma-conditioned implant surfaces. The aim of these studies is to investigate the use of plasma to improve bone cell attachment to titanium implants.

Bacterial diversity of dental intra-implant contamination.

If a denture consists of two parts, germs and biofilms can form in the interior of the denture. The aim of the work is to research the causes and consequences of these biofilms.
