Plaster study models will no longer be accepted when submitting completed orthodontic cases to NHS Dental Services. Instead, 3D digital study models must be submitted. These may be produced by scanning impressions, cast models or by intra-oral scanning but must be in STL file format.

Routine clinical orthodontic monitoring is performed by NHS Dental Services' team of independent specialist orthodontic advisers, usually conducted remotely as a desktop exercise.

Each performer can expect to have a minimum of five completed cases assessed on a three-year rolling cycle. More frequent assessment is arranged if concerns are identified or at the request of the local commissioners.

Orthodontic case assessment forms should be submitted to NHS Dental Services with the following items for each of the five selected cases: all relevant radiographs; copies of intra-oral photographs (where available); a FP17 DCO form; laboratory dockets; and 3D digital study models of the pre- and post-treatment dentition and occlusion for each of the five selected cases.

NHS Dental Services advises that assistance with production of 3D digital images from original plaster study models may be obtained from your local laboratory, and also provides advice and suggests three suppliers at the following link: www.nhsbsa.nhs.uk/DentalServices/4445.aspx.
