Excuse me, I am a German Dentist thus from Europe. Our education is basically the same. I am not saying that in every other part of Europe, or the world Dentistry is as good as here, but as much as I love Americans: you should be more humble ( as you usually are) when it comes to making such generalizations. I am not saying either that a foreign trained Dentist who is qualified should not go through some adapting training, though. However, just assuming that every other Country does bad Dentistry is ignorant and a little bit silly, to say the truth.
By the way, many implant systems,techniques, instruments and devices are invented by Germans and they are being taught and used here in the USA. Just to give you something to think about....
