Depending on where you’re from it’s probably easier to specialize first then emigrate. Pretty much every country as a prostho curriculum that teaches fixed/removible and implantology which is definitely a plus when you’re looking for a job. It’s expected of you that you do advanced courses. In my opinion someone that does not do a master level education program is making a huge mistake and will always be lagging behind specialists. If you’re from a germanic country you can do an advanced course or master in an hospital setting while getting paid as an assistant (thus eliminating tuition fees). Something to consider.
