Patient compliance and orthodontic treatment efficacy of Planas functional appliances with TheraMon microsensors

OBJECTIVES: To assess patient compliance and treatment efficacy of preventive expansion treatment with removable Planas functional appliances using an integrated microsensor.

MATERIALS AND METHODS: Wear time (WT) and behavior of 69 patients undergoing treatment with Planas functional appliances were assessed and analysed using TheraMon microsensors (Gschladt, Hargelsberg, Austria). Patients were followed up for a period of 9 months, and visits were made every 3 months to download WT data from the microsensor and to assess wearing behavior. From individual WT graphs,10 parameters were derived to characterize compliance for each patient. Treatment efficacy was measured by eight parameters determining the level of expansion after 9 months of treatment.

RESULTS: Patients wore their device on average 15.8 ± 5.2 h/d. WT was unrelated to age and gender, but it was positively influenced by patient habits when keeping appliances during eating, sports, care and handling. Treatment efficacy in terms of intercanine and intermolar expansion was 4.4 ± 1.9 mm and 4.6 ± 2.0 mm for the maxilla, and 5.3 ± 2.0 mm and 4.7 ± 2.3 mm for the mandible, respectively. Efficacy was negatively affected by poor compliance (WT < 9 h/d) and by high variability of within-subject WT recordings.

CONCLUSIONS: Perfect compliance is not necessary to achieve treatment success, but patients should exhibit sufficient wear time to allow maxillary expansion to occur. The TheraMon microsensor offers a new perspective and aid to individualize treatment prescriptions.
