For a crown, bridge, inlay or onlay, at either the preparation or the fit visit: anaesthetic, the preparation or try-in, records taken, the lab prescription and shade. One structure follows the case from preparation through to fit.
GDC standard 4.1 expects a patient's clinical record to be made as the appointment happens, and to be accurate and complete.
Assist records the appointment and drafts a note in this structure for the dentist to review and sign off. It writes up what was said in the room, and you check every line before it goes in the record.
