In Vivo Study on The Effects of Vibrations on Orthodontic Tooth Movement

Abstract

Aim & Objective: To compare the orthodontic tooth movement rate between the experimental and control groups and to assess the effect of vibrations on the orthodontic tooth movement in patients undergoing fixed orthodontic treatment.

Materials and Procedures: On 37 fixed appliance therapy orthodontic cases with bilateral maxillary arch first premolar extractions, a split-mouth design study was conducted. All of the participants with type-1 active tiebacks had individual canine retractions. Vibration was given by Oral-B powered toothbrushes (125 Hz) for 10 minutes each day (splits into 5 minutes twice a day). At various time intervals, the tooth movement was clinically assessed using a calibrated digital vernier calliper (T0, T1 and T2). OPGs were collected at the predetermined intervals on a regular basis, and the tooth movement on OPGs was calculated using the grid method.

Results: Data were statistically analysed, and the p-value showed inconsequential difference between experimental side's rate of tooth movement and the control side's.

Conclusions: In individuals undergoing fixed orthodontic treatment, high-frequency vibratory stimulation combined with a fixed orthodontic appliance exhibit negative results. Vibrations from powered toothbrushes fails to speed up tooth mobility.
