Study Overview
=================
Brief Summary
-----------------
The current clinical study will be done for evaluation of maxillary canine retraction assisted with application of two different methods of low-intensity pulsed ultrasound.

Official Title
-----------------
Evaluation of Maxillary Canine Retraction Assisted With Two Different Methods of Low-Intensity Pulsed Ultrasound: A Controlled Clinical Study

Conditions
-----------------
Orthodontic Appliance Complication

Intervention / Treatment
-----------------
* Device: Low-Intensity Pulsed Ultrasound


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: - All patients should satisfy the following criteria: An age ranges from 15-22 years. Severe crowding or protrusion requiring 1st premolar extractions followed by symmetrical canine retraction. All permanent teeth present, 3rd molars are excluded. Good oral hygiene. No systemic disease/medication that could interfere with orthodontic tooth Movement (OTM). No previous orthodontic treatment. Exclusion Criteria: 1. Patient diagnosed to have an indication for non-extraction approach. 2. Poor oral hygiene or periodontally compromised patient. 5 3. Patient with craniofacial anomalies or previous history of trauma, bruxism or parafunctions. 4. Previous orthodontic treatment. 5. Any implanted assistive devices (e.g., pacemakers, cochlear implants, etc.) 6. Pregnant females.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: one- weeks group<br> | Device: Low-Intensity Pulsed Ultrasound<br>* The total sample will be randomly divided into two equal groups (according to method of application of the lipus on the intervention side)as follows: ■ Group I: will include 8 patients who will receive lipus with maxillary canine retraction that will be performed every (3 weeks) on intervention 6 sides according to a standardized protocol. ▪ Group II: will include 8 patients who will receive lipus that will be performed every (1 week) on intervention sides according to a standardized protocol.<br>|
| Experimental: three-weeks group<br> | Device: Low-Intensity Pulsed Ultrasound<br>* The total sample will be randomly divided into two equal groups (according to method of application of the lipus on the intervention side)as follows: ■ Group I: will include 8 patients who will receive lipus with maxillary canine retraction that will be performed every (3 weeks) on intervention 6 sides according to a standardized protocol. ▪ Group II: will include 8 patients who will receive lipus that will be performed every (1 week) on intervention sides according to a standardized protocol.<br>|
