The ‘Guidelines for the Appointment of Dentists with Special Interests (DwSI) in Orthodontics’ is a framework document developed by the Department of Heatlh and the Faculty of General Dental Practice (FGDP, UK) and includes the level of competencies expected and thus the scope of treatment that may be provided by DwSIs in Orthodontics, and contract specification. This document has been written with input from the British Orthodontic Society and representatives of the orthodontic clinical network.
