Course title: Initial Orthodontic Assessment and Clinical Records
This course is aimed at orthodontic nurses who wish to be practically involved in the clinical assessment of patients prior to orthodontic treatment. Learners will be able to undertake dental impressions, orthodontic radiography and clinical photography, and will learn the skill of taking an IOTN assessment on models.
Awarded by: DELTA Awards
Structure: The course is delivered by way of 4 modules. All modules are mandatory and must be passed.


Pass or fail






Candidates must hold GDC registration and a recognised Dental Nurse qualification and be working in an orthodontic environment. This course requires the involvement of a workplace supervisor / expert witness who will take overall responsibility for the practical evidence completed within the workplace. This person will receive their own account login and be required to sign off the evidence submitted. Please ensure you have this person in place prior to course application. Failure to do so will compromise course progress.










This course is assessed by:

  • Dental Impressions – Workplace Portfolio to include case studies, written essay
  • Orthodontic Radiography – Workplace portfolio and final written examination
  • Clinical Photography – Workplace Portfolio
  • IOTN – completion of assignments

Workplace Portfolio of Evidence combined forms 50% of the final grade. Of this, the subject breakdown is:

Impression Taking – 10%
Orthodontic Radiography – 30%
Clinical photography – 10%

Essay submission – an extended essay within the Impression Taking course forms 20% of the overall grade
Final examination – a 60 minute written exam on radiography only contributes to 30% of the overall grade

Candidates must achieve a pass in all modules to gain the certificate.


Resit Arrangements:


Candidates can receive a small course extension to amend or change any information in the case studies or essay submissions. A fee may be applicable.

Candidates get two included attempts at the final examination. Further attempts will be subject to a fee.


Practical Component:


The taking of dental impressions, the taking of orthodontic radiographs (panoramic, occlusal, Cephalometric views and periapical) and the taking of clinical photographs.
