title: Mandibular border positions in eugnathic subjects during the second bite lifting.
abstract: This research was aimed at performing a clinical functional analysis during the second bite lifting, in order to define mandibular border positions and possible differences by sex and/or age. Out of a total of 9680 examined children from the region of Medimurje, Croatia, 103 were found to be eugnathic, with dentition in occlusion during the phase of the second bite lifting. All the eugnathic patients belonged to the class I by Angle, without any caries, fillings or extracted teeth. They were divided into three predefined groups for the sake of comparison. The obtained values of mandibular border positions in eugnathic subjects during the second bite-lifting phase vary with age and with the number of present permanent teeth in occlusion. Generally, all the values are higher in girls than in boys, which speaks in favour of the assumption that mandibular border positions are determined by sex, hormonal activity, growth and intercuspidation. Also, girls show a higher TMJ flexibility as well as a higher mandibular mobility. The knowledge of these facts will contribute to a more precise treatment in child prosthetics and pedodontics.
