Study Overview
Brief Summary
The goal of this Randomized controlled clinical trial is To investigate the effectiveness of AcceleDent Aura vibrating device on rate of canine retraction in orthodontic treatment.. The main question[s] it aims to answer are:
• 1st question In Patients with class II requiring canine retraction it possible to accelerate canine retraction safely using AcceleDent? 2nd question: is accelerating teeth movement effect root condition ? the study will be done on Orthodontic patients with class II requiring canine retraction Excluding Any dental or medical disease affecting tooth movement.
Detailed Description
Introduction:
orthodontic tooth movement(OTM) is a process of mechanically-induced bone modeling where new bone is formed on the tension side and resorbation on the compression side of the periodontal ligament.
One of negative points of orthodontic treatment is long time treatment (24 month ).
Accelerating the speed of orthodontic tooth movement should contribute to the shortening of the treatment period Many approaches was used such as approaches with low-energy laser irradiation and magnetic fields as well as pharmacological approaches with the injection of prostaglandin E2 (PGE2) and However, many side effects, such as local pain, severe root resorption and drug-induced side effects have been reported.
A new device called AcceleDent(OrthoAccel technologies,Inc, USA) has been introduced to the market and aims to achieve an increased rate of tooth movement by enhancing bone remodelling using pulsating forces. Invented by Dr. Jeremy Mao, it is intended to be used by a patient in conjunction with fixed orthodontic appliances or removable sequential aligner treatment for 20 mins per day. It vibrates at a frequency of 30Hz and has force amplitude of 20 grams.

Outcomes
Primary Outcomes
Rate of Canine Retraction in mm Per Month
Time Frame: 6 month
. Retraction of the canine was done using NiTi coil spring delivering a force of 150 gm per side calibrated using digital force gauge, attached between the hook of the canine bracket and the first molar tube on a of 16\*2 stainless steel basal archwire. The intervention group subjects were given AcceleDent devices which delivered gentle micropulses (0.25 N at 30 Hz) and were instructed to wear them every day for 20 mins according to the manufacturer instructions. The patient compliance to intervention instructions were monitored by asking the patient and writing every day on chart how long she used it and compare this with the data download from the appliance that recorded their daily usage during the period of space closure. Follow-up visits were scheduled every four weeks. At each follow up visit, recalibration of the NiTi retraction spring was done using the same force gauge when necessary to maintain 150 gm force delivery.
