Bones from calves good for fastening tooth implants

05.11.2002


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.


In a comparative study using three types of implants (bone from the jaw, bone from the jaw combined with bone from calves, and bone only from calves), no differences were noted regarding the development of new bone and the final results from the implant, apart from the fact that the alternative using only calf bone required three months longer to heal.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
