Abstract: Orthodontic plaster casts are fragile and bulky, and an alternative method of storage which allows accurate dental cast measurement is desirable. Four examiners determined the IOTN scores from 30 sets of plaster casts on two occasions and their threedimensional digital equivalents on two occasions. Three-dimensional digital models were found to be suitable substitutes for plaster models when scoring the Dental Health Component of the IOTN. However, there was less agreement in the scores for the Aesthetic Component.

Clinical relevance: The application of three-dimensional digital casts in orthodontics.
