Accelerated Tooth Movement With AcceleDent® and Aligners - a Pilot Project

University of Washington27 enrolled

Overview

The AcceleDent® device has been introduced to the specialty of orthodontics in order to reduce treatment time. The theory behind AcceleDent® is that high frequency vibratory forces (30Hz) delivered to the teeth will stimulate the bone remodeling that is necessary for tooth movement to occur more quickly. Additionally, one claim of the AcceleDent® product is that it may reduce pain and discomfort during orthodontic treatment. This study will be a parallel group, triple-blind randomized clinical trial comparing two groups of subjects with 12 participants in each group. Subjects will be randomized to receive one of two vibrational units, which will differ in frequency and/or amplitude of vibration. The subjects will be asked to change their aligners every week instead of every 2 weeks, which is common with Invisalign.

Outcomes

Primary Outcomes

Ability to Complete Treatment Aligners in Conjunction With an Active and Placebo Vibration Device (AcceleDent® Aura)

The outcome was the ability to complete the initial set of aligners using either an active vibration device or a placebo vibration device. Regardless of the group assignment, patients were asked to change their aligners each week, and we tracked the percentage that were able to complete their series of aligners.

Time frame: 6 months

Secondary Outcomes

Final Alignment Scores of the Upper and Lower Incisors

Final alignment was measured using Little's incisor irregularity index. This index sums the displacement of the contact points of the anterior teeth, to produce a millimetric number. The lower the score, the more perfect the alignment.
