Intermittent Vibrational Force and Orthodontic Tooth Movement

King's College London

Status: Completed

Conditions: Fixed Orthodontic Appliances; Vibrational Force; Dental Crowding

Treatments: Device: Sham AcceleDent device; Device: AcceleDent vibrational device; Other: Fixed appliance only

Study type: Interventional

Funder types: Other

Identifiers

NCT02314975

11/LO/0056

Details and patient eligibility

About

The aim of this study is to compare the clinical efficiency of conventional fixed appliance orthodontic treatment with that supplemented by the daily application of cyclic forces to the dentition via a removable (AcceleDent) vibrational appliance. The primary outcome measure is rapidity of tooth alignment; whilst secondary outcome measures include pain and discomfort during treatment, rapidity of orthodontic space closure, changes in arch dimensions and root length.

Enrollment: 81 patients
