NCT ID: NCT04348526 Completed - Crowding Clinical Trials

Evaluation of the Levels of Pain and Discomfort Between Two Methods of Leveling and Alignment

Start date: March 15, 2017
Phase: N/A
Study type: Interventional

The duration of orthodontic treatment is one of the exacerbation causes of orthodontic pain. Several methods have been suggested to reduce the duration of orthodontic treatment classified to surgical and non-surgical methods. Researches used minimally invasive surgical methods like corticision, piezocesion, micro-osteoperforation, and piezo-puncture indicated that most of these methods can accelerate dental movement by 20 - 40% without causing additional pain as a result of using those methods. Applying corticision on the lower anterior teeth using a surgical blade and a hammer may accelerate tooth alignment during orthodontic treatment. This study consists of two groups, patients will be randomly assigned to one of these two groups.

NCT ID: NCT03850951 Completed - Crowding Clinical Trials

Comparison Between Lingual and Labial Fixed Orthodontic Appliances in the Treatment of Crowding Cases

Start date: February 22, 2018
Phase: N/A
Study type: Interventional

Patients who have moderate crowding that could be treated without extraction will be treated in this study using either lingual or labial fixed orthodontic appliances. All patients will receive a cone-beam computed tomography (CBCT) scan in two different times (T0: before treatment, T1: after treatment). The dentoalveolar changes will be assessed.

NCT ID: NCT03646942 Completed - Clinical trials for Malocclusion, Angle Class I

The Role of Low Level Laser Therapy in Acceleration of Teeth Alignment in Lingual Orthodontic Patients

Start date: June 15, 2017
Phase: N/A
Study type: Interventional

We will treat patients with class I malocclusion who have moderate crowding (4-6 mm) according to Little's irregularity index and asses the efficacy of low level laser therapy in accelerating orthodontic tooth movement . There is two groups : 1. treated with Low level laser therapy (LLLT) 2. treated traditionally without any irradiation Patients will be randomly allocated in any group and all data will be collected through photographs when leveling and alignment completed. Also pain levels will be assessed using numeric rating scale to compare between the two groups and if laser really can relief pain or not .

NCT ID: NCT03645356 Completed - Clinical trials for Malocclusion, Angle Class I

Comparison Between Clear Aligners and Traditional Fixed Appliances in the Treatment of Four-premolar-extraction Cases

Start date: August 19, 2018
Phase: N/A
Study type: Interventional

Patients who have severe crowding that require four premolars extraction will be treated in this study. The efficacy of the clear aligners and vestibular fixed appliances will be assessed. The treatment result of these two different methods will be explored using the Peer Assessment Rating (PAR) in two different times (T0: Before treatment, T1: After treatment) and the American Board of Orthodontics Objective Grading System (ABO-OGS) after treatment (T1). There are two groups: First group (Experimental): the patients in this group will be treated using clear aligners. Second group (Control): the patients in this group will be treated using fixed appliances.

NCT ID: NCT02996292 Completed - Crowding Clinical Trials

Treatment of Crowding Without Extraction Using Self Ligating Brackets

Start date: September 2016
Phase: N/A
Study type: Interventional

This experimental study will evaluate the effect of active and passive self-ligating brackets in treatment of crowding, compared with the control group of conventional brackets in class I malocclusion without extraction. The study sample will consist of 66 patients with 3-6mm crowding. The sample will be allocated randomly into two experimental groups, in addition to a control group. The brackets will be applied using indirect bonding method for all patients. The dentoalveolar changes occurring after leveling and alignment teeth will be assessed by using CBCT radiographs; pre and post- treatment changes for each group will be evaluated individually.

NCT ID: NCT02415673 Completed - Crowding Clinical Trials

Alignment Efficiency of Two Thermal Activated Orthodontic Archwire Sequences

Start date: August 2010
Phase: N/A
Study type: Interventional

The aim of the present study was to compare the effectiveness of two alignment sequences with thermal activated archwires with different Af temperatures applied for the correction of mandibular anterior crowding

NCT ID: NCT01402635 Completed - Crowding Clinical Trials

Can the Point-Of-Care Chemistry Test (POCT) Solve the Emergency Department (ED) Crowding?

POCTED
Start date: January 2011
Phase: N/A
Study type: Interventional

The hypothesis of this study that the Point-Of-Care Chemistry Test (POCT) may shorten Emergency Department (ED) length of stay (LOS).
