summary This study investigated the relationship between static and dynamic occlusion in school children. A total of 447 subjects, within an age range of 14–17 years with no history of orthodontic treatment or trauma to the teeth were included in this study. Static occlusion was determined for both incisal and molar relationship. Dynamic occlusion was determined in lateral and protrusive movements of the mandible. The majority of the subjects had class I static occlusion for both incisor and molar relationship (45 and 54%, respectively). Canine‐guided occlusion was the dominant type of dynamic occlusion (57%) and most of the subjects had no posterior contact in protrusive movement (78%). There was an association between canine guidance with class II static occlusion. Statistically, a significant relationship was found between the dynamic and static occlusion of the incisor ( P < 0·001) but not with the molar ( P > 0·05).
