[Distalization of upper molars: a new approach (biomechanical)].
The showed system has the peculiarity of having a coil spring as an active and continuous force. The anchorage is partly included into the system and only partly depends on the cooperation of the patient. The use of extraoral traction is optional, it is necessary only when an excessive molar tipping is noted. The system can be used in both symmetric and asymmetric distalization cases.
