['The aim of this study was to investigate whether microelectronic wear-time documentation can contribute to individualized orthodontic management.', 'The wear times and behaviors of 281 patients undergoing orthodontic treatment with removable appliances were quantified and analyzed using the TheraMon microelectronic system (Sales Agency Gschladt, Hargelsberg, Austria) over a 6-month treatment period.', 'The 281 study participants wore their removable appliances for a median of 9.0 hours per day, compared with the 12 to 15 hours per day prescribed. Wear behavior was variable and heterogeneous in patients with almost identical median wear times, with fluctuating and numerous zero wear-time periods observed.'] Does microelectronic wear-time documentation of removable orthodontic devices detect heterogeneous wear behavior and individualizes treatment planning?
