My husband went to Zahnartztpraxis Claradent at Claraplatz 1 in Kleinbasel for emergency extraction treatment,

A Spanish friend of ours had to have a number of top set implants done and resorted to going back to Madrid for this as she was quoted about 120k CHF in Basel.
Husband has had 2 implants done since he moved here, but he went back to Scotland for this as he'd already had one done prior to coming to Basel and wanted the same maxillofacial surgeon. Ridiculous thing is all of his implants are made in Basel (Straumann), but it was much cheaper to fly back to Scotland to get them fitted. We have insurance with our dentist back there so pre Covid went back for checkups and hygiene. The insurance covers us for emergencies in EU/EFTA countries.
