Efficiency of Piezocision-assisted Orthodontic Treatment in Adult Patients

Not Applicable

Completed

• Conditions: Tooth Overcrowding
• Interventions: Procedure: Piezo-assisted orthodontics (only the Test group)

• Registration Number: NCT02590835
• Lead Sponsor: Dr. France LAMBERT

Brief Summary

This study was designed as a randomized controlled clinical trial to compare conventional orthodontic treatment (control group) and piezocision-assisted orthodontic treatment (PS group). Twenty-four consecutive adult patients from the Orthodontics Department of Liege University Hospital, Belgium who met the inclusion criteria were enrolled from January to October of 2013.

Arm && Interventions

Group	Intervention	Description
Test group	Piezo-assisted orthodontics (only the Test group)	subjected to piezo-assisted orthodontics

Primary Outcome Measures

Name	Time	Method
Overall treatment time measurement (in days)	3 years	Comparaison of the overall treatment time between the test group (piezocision group) and the control group will be performed. It will be evaluated by measuring the time (in days) between the placement and the debond of the orthodontic appliance. The hypothesis is that piezocision accelerate orthodontic tooth movement.

Secondary Outcome Measures

Name	Time	Method
Root resorption parameters measurements (intrabuccal radiographic in millimeters)	3 years	A comparaison of orthodontic parameters (root resorption) between the test group and the control group before and after orthodontic treatment will be performed. The root resorption will be measured in intrabuccal radiographic (millimeters) on the day of the placement of this appliance and at the debond.
Comparaison of periodontal parameters between the test group and the control group before (at baseline) and after orthodontic treatment.	3 years
Patient-centered outcomes (VAS questionnaire)	7 days	Satisfaction post treatment using a VAS questionnaire and analgesic consumption (milligrams of paracetamol) during 7 days after the placement of the orthodontic appliance.
