Innovative implants benefit both patients and caregivers

14.12.2009
Researchers at Mid Sweden University, together with Professor Jan Hirsch and Consultant Per Dérand, oral & maxillofacial surgeons at Uppsala University Hospital and Mälarsjukhuset Hospital, respectively, have developed an entirely new method for individually adapted implants.

The method provides better patient safety and lower costs. It involves planning, design, and production. At the end of October the first implants were operated in at University Hospital in Uppsala.

"With individually adapted implants, you minimize the time needed for adjustment and adaptation of the implant during the operation itself. Work that was previously done during the operation is now done in advance, on a computer.

This means that the operation time can be reduced. But the hypoxia time, that is, the time the transplant has no supply of oxygen, is reduced for the transplant in that it is finished before the blood circulation is cut off. With this type of digital planning and production method we also see a potential for making entirely new types of implants and prostheses that don't exist today," says Lars-Erik Rännar, who does research in sports technology at Mid Sweden University.

In brief, the method involves planning complicated jaw reconstruction in advance, using a computer. The patient's anatomy is determined with the use of x-rays, with the images forming the basis of a three-dimensional model of the patient. With the help of the model, the operation is planned, along with the design of the implant and other aids that are needed for the operation. The digital models are then used as a basis for manufacturing the implant at Mid Sweden University's laboratory for additive manufacturing technology, which is unique in the world. The technology functions like a three-dimensional printer where the results are solid details made of bio-compatible titanium.

"When it comes to medical applications, we have previously worked with design and production methods for hip implants," says Lars-Erik Rännar. "What's special about this project is that we have arrived at a well-developed method very quickly, and everyone involved believes it has a very exciting future. The benefits for patients and caregivers are tremendous."

Im Focus: LaserTAB: More efficient and precise contacts thanks to human-robot collaboration

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.

Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
