Qualification for Orthodontic treatment under the NHS is partly determined by IOTN. IOTN stands for Index of Orthodontic Treatment Need and is used to measure the severity of the problem relating to the positions of the teeth. IOTN is used to define NHS acceptance criteria which determines whether you or your child will receive treatment through the NHS.


Dentists will screen patients prior to referring to Osborne Orthodontics but may refer you if they are unsure and require an opinion as to the need for Orthodontic treatment to take place. 


Scores of 2 or less

If your IOTN score is two or less then there is zero or very little need for orthodontics treatment


In this instance NHS orthodontics treatment is unlikely to occur but treatment will be available on a private basis if you're willing and able to do so. If cost is an issue then we can offer flexible payment plans to make your treatment more affordable.


Score of 3

If your IOTN score is three then you are deemed to be borderline in terms of your requirements for orthodontics treatment


When a patient scores a 3 we will usually take images of their oral condition to help determine in more detail if a higher score is necessary after further analysis. This will be explained and demonstrated during the appointment if the orthodontist believes it is necessary.


Score of 4

If your IOTN score is a four then you are deemed to be in need of orthodontics treatment.


Score of 5

If your IOTN score is a five then you are deemed to be in great need of orthodontics treatment.
