A total of 53 anonymised study models were selected as a convenience sample of patients attending hypodontia multidisciplinary clinics. A range of cases with different amounts of spacing in each arch was chosen. Each model was measured by ML-C in millimetres using calibrated Vernier callipers and then subdivided to give the gold standard spacing TSI categorisation of mild, moderate or severe. Two test raters (CB and NM) then visually assessed the same study models and rated the spacing as mild, moderate or severe.
