Woman's infected jaw removed, 3D printed replacement implanted

An 83-year-old woman with a badly infected lower jaw had the entire thing replaced with a 3D printed titanium/bioceramic replica. The surgery was performed by doctors from the University of Hasselt (Belgium) in collaboration with Dutch surgeons.

The 3D printer prints titanium powder layer by layer, while a computer controlled laser ensures that the correct particles are fused together. Using 3D printing technology, less materials are needed and the production time is much shorter than traditional manufacturing. The mandible was finally given a bioceramic coating compatible with the patient's tissue by BioCeramics in Leiden. The artificial jaw weighs 107 grams, it is only 30 grams heavier than a natural jaw, but the patient can easily get used to it.

The operation was performed in June last year in the hospital in Sittard-Geleen. One day later the lady could start talking and swallowing.
