On Friday, November 8, Mats Hallman, Department of Odontology, Jaw Surgery, Umeå University in Sweden, will defend a thesis that presents favorable results from implanting bone powder from calves to anchor tooth implants in humans.
Tooth implants have long been a well-tested method to create permanent teeth in toothless sections of the jaw. In certain cases, however, patients have no bone in which to secure the titanium screws. In these cases it is necessary to rebuild the bone prior to the implant operation. This bone has usually been taken from the patients’ own hip or jaw, which has required further surgery and caused problems where the bone was taken from. Since many of these patients are elderly, complications have often arisen after the operation. This surgery also entails greater costs.
The dissertation scientifically tests whether it is possible to implant bone replacement material, bone powder from calves, instead of using the patients’ own bones. The studies indicate that the methods functions at the cellular level, histologically, and in practice, clinically. When the bone material is packed against the patient’s remaining bone, the bone cells are “fooled” into forming new human bone. The thesis also shows that the supplemental bone resists deterioration (resorption) and functions as an excellent support for tooth implants.

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
