The Effect of Ultrasound on Orthodontic Tooth Movement

Not Applicable

Completed

Brief Summary: To study whether or not the Aevo System™ medical device enhances the rate of tooth movement in human subjects who use orthodontic braces.

Detailed Description: The study will involve comparing the effects of tooth movement with and without ultrasound treatment in a split mouth design. Treatment will consist of using the Aevo System™ device for one 20 minute period per day for the duration of the trial (up to 24 weeks). Tooth position measurements will be taken from eligible patients prior to commencing usage of the study device. Follow-up visits will be scheduled for intra-oral clinical measurements and to take full-arch impressions. The Aevo System™ consists of an ultrasound emitting mouthpiece which is wire connected to an external handheld device. The mouthpiece is placed over the teeth and over the braces every day for 20 minutes in order to deliver the therapy.

Arm && Interventions

Group	Intervention	Description
Treatment Arm	Ultrasound	20 minutes per day of ultrasound treatment on the active side of the device. The device consists of a mouth guard type device with transducers embedded in the mouth guard. In the split mouth design, the treatment arm consist of the side of the mouth with the transducers activated.
Control Arm	Sham comparator	The transducers are not activated on the control side of the device.The subjects wear the device for 20 minutes per day for the duration of the study. The device consists of a mouth guard type device with transducers embedded in the mouth guard. In the split mouth design, the control arm consist of the side of the mouth with the transducers deactivated.

Primary Outcome Measures

Name	Time	Method
Rate of Tooth Movement	24 weeks or until the extraction space was closed (whichever came first)	The weekly rate of tooth movement (mm/week) as compared between the treated side and the control side.

Secondary Outcome Measures

Name	Time	Method
Rate of Root Resorption	24 weeks or until the extraction space was closed (whichever came first)	The weekly rate of tooth root resorption (mm/week) as compared between the treated side and the control side.
Discomfort	24 weeks or until the extraction space was closed (whichever came first)	Average measured level of subject discomfort or pain. The Participant Pain Reporting Scale is used to assess the amount of pain on a 10 point scale. On the 10 point scale, 1 represents the least amount of pain and 10 represents the most amount of pain.
