Outcome Measures
Primary Outcomes (1)
Masticatory movements during mastication
A jaw tracking device was positioned on subjects face, who were asked to chew an artificial material in their habitual way. Tracings of jaw lateral movements during mastication were analyzed to classify in which side each chewing stroke was taken. If 80 percent or more chewing cycles were classified as left or right, the subjects were considered as unilateral chewer.

Study Arms (3)
Brachyfacial
Subjects with a horizontal facial growth pattern
Mesofacial
Subjects with a balanced facial growth pattern
Dolichofacial
Subjects with a vertical facial growth pattern
