Practice in this context goes wider than clinical dental technology to include teaching, research, and management, given that such roles influence clinical and technical practice and public safety.

Areas of clinical dental technology practice which were not included in a practitioner’s training should not be undertaken unless the practitioner has completed appropriate training and practises to the standard required by the Dental Council Policy on Advanced Areas of Practice and the Code of Practice on The Practice of Dental Technology and Clinical Dental Technology and the working relationship within the Practice of Dentistry.
