Abstract

The purpose of this study was to investigate the relationship between incisor and condyle movement during protrusion in children with primary dentition. Subjects were categorized into two age groups. A primary dentition group consisted of 20 children, and a permanent dentition group consisted of 25 women. The occlusion and TMJ in both groups were normal, with no history of orthodontic treatment. Three orthogonal excursive ranges, linear distance and curvilinear distance of the incisal and condylar points; sagittal angle of condylar rotation; and correlations between incisor and condyle distances during protrusion were estimated by using multilevel statistical models. Protrusion in children with primary dentition was characterized by: 1. significantly smaller superior-inferior ranges for incisal and condylar points in children than in adults; 2. strong positive correlations between incisor and condylar anterior-posterior ranges and linear distances, a pattern similar to that in adults.
