Effectiveness of vibrational forces on orthodontic treatment : A randomized, controlled clinical trial.

AIM

AcceleDent® Aura (OrthoAccel® Technologies, Bellaire, TX, USA) is a class II medical device with U.S. Food and Drug Administration approval that uses SoftPulse Technology™ to increase the speed of tooth movement. The aim of this study was to evaluate the application of vibrational forces on the rate of canine distalization.

METHODS

A total of 20 patients (10 boys and 10 girls) who had class II division 1 malocclusion or severe crowding and indicated first premolar extractions for treatment were included in the study. The patients were divided into two groups: 8 in the control group and 12 in the study group. Three-dimensional digital models were taken just before canine distalization and after space closure using the 3Shape TRIOS® R700 (3Shape Inc., Copenhagen, Denmark) device. Linear measurements between molars and canines were evaluated. The results were assessed with SPSS 23.0 program (IBM, Armonk, NY, USA).

RESULTS

One subject was excluded from the study group due to insufficient oral hygiene and poor patient compliance. Tooth movement rates were 1.06 mm/month for mandibular and maxillary canine teeth in the control group. In the study group, tooth movement rates were 1.24 mm/month for maxillary canines and 1.09 mm/month for mandibular canines. These differences were not statistically significant (p > 0.05).

CONCLUSION

AcceleDent® Aura is an easy-to-use device; however, in our study its application did not have any positive effects on canine retraction rates.
