Examiner Tips

Expert advice for maximising your marks

💡In written assessments, always relate your answers back to the General Dental Council's Scope of Practice for Orthodontic Therapists to demonstrate professional awareness.
💡During practical observations, verbalise each step of your clinical reasoning, especially when adapting techniques for individual patient anatomy or medical history.
💡When presenting evidence portfolios, include reflective accounts that link incidents to theoretical models of orthodontic tooth movement and biomaterials science.

Common Mistakes

Pitfalls to avoid in your exam answers

Confusing the indications and contra-indications for the use of fixed versus removable orthodontic appliances in different malocclusions.
Inconsistent infection control practices, particularly when handling and storing dental impressions and orthodontic appliances.
Failing to accurately fit and activate headgear or other adjunctive appliances, leading to patient discomfort or ineffective treatment.
