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: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
