The aim of the current clinical trial was to evaluate the effects of premolar extractions compared with non-extraction orthodontic treatment on the skeletal vertical dimension of the face.

The null-hypothesis is that there is no difference in post-treatment skeletal vertical characteristics of normodivergent and hyperdivergent patients treated orthodontically with first premolar extractions compared with patients treated in non-extraction manner.
