[Relationships between occlusal guidance in laterotrusion and jaw relation]

This study was an attempt to clarify the relationships between antero-posterior jaw relations and lateral excursive patterns. The age of the 538 patients studied ranged from 12 to 30 years. Although it was impossible to draw any general conclusions, some trends could be revealed: 1. The results suggest a relationship between angle class and the lateral excursive pattern. 2. Group-function occlusion was observed to occur twice as often in patients over 20 years of age than in younger persons, more often than not these had cuspid guidance. 3. The percentage of group-function occlusion increased in proportion with the degree of cuspid abrasion and the age of the patients.
