Dental Prosthetists are denture experts and mouthguard specialists. They work both in the clinic and in the lab.
Dental technicians on the other hand can only work in the lab and are not allowed direct contact with patients such as impression taking as they were not trained to do that. In order to be able to work in the clinic dental technicians must undergo a further education in prosthetics that qualifies them to provide more specialised services for removable oral appliances and also to allow them direct contact with dental patients.
