Vertical dimension of the face: Result of four premolar extractions or posterior teeth position

We have read and discussed with great interest the article entitled "Effect of orthodontic treatment with four premolar extractions compared with nonextraction treatment on the vertical dimension of the face: A systematic review" (Kouvelis G, Dritsas K, Doulis I, Kloukos D, Gkantidis N. Am J Orthod Dentofacial Orthop. 2018; 154:175-87), in which the authors searched for scientific evidence of the relation between the 4 premolar extractions during orthodontic treatment and variations on the vertical dimension of the face.
