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."

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
