title: [Biomechanical fundamentals in the use of the transpalatal bar and the lingual arch].
abstract: The Authors deal systematically with the transpalatal bar and lingual arch biomechanics. Particularly passive applications are distinguished from active ones. The Authors propose a classification of active applications based on the activation order (first, second, third), on the kind of biomechanics of the system (statically determinate or indeterminate) and on the symmetry or asymmetry of the activation. Every group of this classification is then analysed in detail.
