From W. Duncan Robertson
I am a little concerned that the biomedical research department of the University of Hasselt in Belgium seem to have placed a set of upper teeth on the fabricated titanium lower jaw shown in the photo accompanying your report on printing jawbones (11 February, p 7).
One can spot the mistake by the size of the teeth and the natural curve they should assume in the mouth. I would hate readers to think that these teeth were the outcome for this patient.
I am, however, very impressed by the titanium jawbone.
