Abstract
Objective
This prospective clinical study aimed to evaluate the immediate impact of Twin‐block appliance insertion on the sleep of adolescents using a wearable device.
Materials and Methods
A total of 24 girls, aged 11‐13 years, with Class II division 1 molar relationship, skeletal class 2 malocclusion (ANB ≥5) and overjet measuring ≥5 mm were selected. Exclusion criteria included a history of previous orthodontic treatment, systemic disease, irregular sleep pattern, obstructive sleep apnea, medical history of breathing disorders, or concurrent use of medications. Participants wore a wearable device to measure sleep parameters, including deep sleep, light sleep, minutes awake during sleep, wake‐up times, bedtimes and total sleep times. The participants wore the device for 10 days prior to Twin‐block insertion and sleep data were collected for another 10 days after insertion.
Results
Following the insertion of the Twin‐block appliance, there was a highly statistically significant shift in bedtime and wake‐up time to later hours (P < .001). All participants experienced a highly significant delay in bedtime compared to the recommended 10 pm time (P < .001). Additionally, there was a significant increase in the duration of light sleep (P < .05). However, the effect on deep sleep, minutes awake during sleep and sleep duration was not statistically significant. None of the sleep parameters tested showed statistically significant changes between the first 5 days after Twin‐block insertion with the subsequent 5 days.
Conclusion
The immediate insertion of the Twin‐block appliance disrupts sleep onset, wake‐up time and light sleep during the specified period of 10 days.
