Research Interests

In cranio-maxillofacial and oral surgery the substitution of a mandible to restore resections of tumors for example, still poses a great challenge. To overcome this problem our oral Biotechnology and Bioengineering laboratory works on the development of new osteoconductive bone substitute materials and their combination with osteoinductive bone morphogenetic proteins, and epigenetically active small molecules. Based on our capabilities to design and produce ceramic based scaffolds with additive manufacturing, we try to unravel the essence of osteoconduction as important driving force of bone regeneration. The materials we use and develop range from degradable polylactide based materials, to natural and synthetic hydrogels, like fibrin and polyethylenglycol-(PEG)-based hydrogels, to titanium and ceramic based scaffolds produced in a patient specific shape by additive manufacturing. The delivery of osteoinductive bone morphogenetic proteins, including epigenetically active enhancers of bone morphogenetic proteins and degradable, bioactive guided bone regeneration membranes are other fields of expertise of our laboratory. Moreover, we work on the regeneration of the pulp using natural and synthetic hydrogels and diverse factors with the aim to extend the lifetime of teeth.
