Microelectronic wear-time documentation of removable orthodontic devices detects heterogeneous wear behavior and individualizes treatment planning

Objective assessment of compliance with intra- and extraoral removable appliances

“…This is in line with the literature in which compliance never exceeds 7 to 9 hours of the prescribed 8 to 15 hours per day, [19][20][21][22][23][24] indicating that only nocturnal wear can be predicted with any degree of certainty. Indeed, Schäfer et al 24 found that compliance was only close to that required (ie, more than 12 hours per day) in 7% of patients, and Schott and Ludwig 22 emphasized that 25% of patients wore their appliance for much less The degree of compliance does not appear to be related to the type of appliance, as Schott et al 21 found comparably low compliance in both active (functional) and passive (Hawley retainer) appliances. Our data enabled us to confirm this conclusion because no statistically significant difference in compliance was observed between different types of intraoral devices or between intraoral and extraoral appliances.…”

“…Studies on the TheraMon compliance monitoring system show that compliance is invariably less than that requested by the orthodontist, [19][20][21][22][23][24] and our study in particular revealed a compliance of 8.6 6 2.9 hours per day when 13 hours' wearing time was prescribed. This is in line with the literature in which compliance never exceeds 7 to 9 hours of the prescribed 8 to 15 hours per day, [19][20][21][22][23][24] indicating that only nocturnal wear can be predicted with any degree of certainty.…”

“…Thus the system can give the orthodontist a clear picture of a patient's compliance profile, providing information as to the mean compliance (hours/day) during the course of each day or a throughout a selected period 16,18 ( Figure 2). Authors have used TheraMon micro sensors to study compliance with various types of removable appliances, [19][20][21][22][23][24] and functional appliances and retainers have been investigated at prescriptions ranging from 8 hours to 15 hours per day in patients aged between 6 to 16 years, and in all cases the chips revealed compliance far lower than that required. However, no similar study has yet been conducted on extraoral orthopedic devices, and there is as yet no consensus as to how age and gender affect compliance with various types of intra-and extraoral appliances.…”

Quantification of wear-time adherence of removable appliances in young orthodontic patients in relation to their BMI: a preliminary study

“…The majority of these young patients showed discontinuous wear behavior,39 the typical pattern being to not wear the device on some days and then trying to compensate for this by wearing the device more on other days. Overall, this discontinuous wear behavior resulted in a low median wear time, and remotivating the patient during consultations can persistently reduce the number of zero wear-time days over the course of subsequent therapy.…”
