Accuracy of thermal microsensors embedded in orthodontic retainers of different material composition and thickness: An in vitro study

Abstract Objectives: The present research aimed to assess the accuracy and precision of TheraMon ® microsensor embedded in different thicknesses Hawley retainers (HR) for comparison with vacuum formed (VFR). Methods: Thirty microsensors contained within composition were divided into three equal groups: Group A thick coverage HR (3 mm), B thin (1 C VFR mm). immersed thermostatic water at a controlled temperature 35°C, which corresponds average intra-oral temperature. After 1 week, data gathered using client software analysed ANOVA Turkey’s HSD tests. Results: All TheraMon® functional produced uninterrupted recordings during 1-week test period. Thermal detection differed between removable retainer groups. near accurate was noticed mean 34.81 ± 0.04°C, followed by 34.77 0.09°C, finally 34.73 0.05°C (ANOVA p -value = 0.025). between-group showed significant difference (MD) groups (MD: 0.08, 0.01). However, there no differences neither 0.04, 0.27) nor group -0.03, 0.39). Conclusion: retainer’s variation material thickness could induce small but detectable changes thermal microsensors.
