NCT ID: NCT05183451 Completed - Clinical trials for Bimaxillary Protrusion

Effect Of Low Level Laser Therapy on the Rate of En- Masse Retraction: RCT

Start date: December 2, 2018
Phase: N/A
Study type: Interventional

There is scarcity in the literature regrading the effect of Low Level Laser Therapy (LLLT) on the rate of en-masse retraction. This study aims to investigate whether LLLT would affect the rate of en-masse retraction in females having bimaxillary dento-alveolar protrusion.

NCT ID: NCT05150665 Active, not recruiting - Clinical trials for Bimaxillary Protrusion

Evaluation of Mini and Macro-esthetics Following En- Masse Retraction Versus Two Step Retraction

Start date: October 29, 2020
Phase: N/A
Study type: Interventional

There's a scarcity in literature concerning mini-esthetics specially maxillary gingival display changes following en-masse retraction and two-step retraction. The purpose of this study is to determine, In orthodontic patients with maxillary protrusion, which technique of retraction will result in better esthetics upon smiling following en-masse retraction or two step retraction mechanics.

NCT ID: NCT04921579 Completed - Clinical trials for Bimaxillary Protrusion

Evaluation of Treatment Duration of En-masse Versus Two Steps Retraction in Patients Having Maxillary Protrusion

Start date: December 15, 2019
Phase: N/A
Study type: Interventional

Brief summary: there's a scarcity in literature concerning time needed to retract anterior segment following premolars extraction. the purpose of this study is to determine, in orthodontic patients with maxillary protrusion, which form of technique of retraction offers a faster treatment duration of retraction : en-masse or two step techniques

NCT ID: NCT04905004 Recruiting - Clinical trials for Class II Division 1 Malocclusion

Efficiency of Canine Retraction Using Different Reactivation Intervals

Start date: April 1, 2017
Phase: N/A
Study type: Interventional

Canine retraction after 1st premolar extracion into the extraction space is a routine treatment in orthodontics. Orthodontic patients requiring first premolar extraction, canine retraction and maximum anchorage were recruited for this randomized controlled trial. A search of the literature did not indicate the ideal frequency of elastomeric chain reactivation for optimum canine retraction. The study was approved by the ethical committee. The first premolars were extracted. Elastomeric chains were used to retract the canine distally into the 1st premolar space. The optimum reactivation interval was evaluated regarding the efficiency of treatment in terms of rate of canine retraction, canine tipping and rotation, root resorption and pain at the intervals of 2, 4, 6 and 8 weeks. Three dimensional imaging, as well as digital scanning were the methods for data collection.

NCT ID: NCT04902456 Active, not recruiting - Clinical trials for Bimaxillary Protrusion

Evaluation of the Anchorage Loss During En-masse Retraction in Orthodontic Patients With Maxillary Protrusion

Start date: December 29, 2020
Phase: N/A
Study type: Interventional

There is scarcity in literature regarding the effectiveness of friction and frictionless mechanics during ''En-masse retraction''technique on anchorage loss of posterior segment in orthodontic patients with maxillary protrusion. Moreover there is deficiency in studies measuring the patient pain and satisfaction regarding the different techniques of retraction. The aim of the current study is to evaluate the effects of friction versus frictionless mechanics, implemented during "En-masse retraction", on anchorage loss. Additionally, assessment of both techniques regarding their rates, effects on root resorption as well as patient satisfaction.

NCT ID: NCT04902430 Completed - Clinical trials for Bimaxillary Protrusion

Evaluation of the Rate of En-masse Retraction in Orthodontic Patients With Maxillary Protrusion

Start date: December 29, 2020
Phase: N/A
Study type: Interventional

There's a scarcity in literature concerning en-masse retraction and its effect on the rate of tooth movement. The purpose of this study is to determine, In orthodontic patients with maxillary protrusion, which form of mechanics in en-masse retraction offers a faster rate of retraction; Friction or Frictionless Mechanics.

NCT ID: NCT04892056 Completed - Clinical trials for Bimaxillary Protrusion

Evaluation of the Rate of Anterior Segment Retraction Using Two Types of Mechanics

Start date: February 1, 2019
Phase: N/A
Study type: Interventional

The rate of anterior segment retraction in bi-maxillary protrusion cases was evaluated comparing the friction and friction-less mechanics. since, there has been a lack of clear cut guidelines for clinicians for the optimum method for retraction, this randomized clinical trial was done.

NCT ID: NCT04887974 Completed - Clinical trials for Class II Malocclusion

Canine Retraction With Temporary Anchorage Devices

Start date: April 2, 2016
Phase: N/A
Study type: Interventional

Various malocclusions require the extraction of the first premolars and retraction of the canines with the need for maximum anchorage. If the canines are pulled into the extraction space using the molar teeth for support, unwanted tooth movement occurs. This study aims to evaluate the effect of temporary anchorage devices and power arms, which are auxiliary orthodontic appliances in reducing undesirable tooth movements.

NCT ID: NCT04878939 Completed - Clinical trials for Bimaxillary Protrusion

Evaluation of Incisors' Position Following Anterior Segment Retraction

Start date: February 4, 2019
Phase: N/A
Study type: Interventional

There's scarcity in literature concerning the issue of anterior segment retraction technique and its effect on anterior teeth position. Therefore, a randomized clinical trial has been chosen to investigate this issue, aiming to support clinicians with the best guidelines for anterior segment retraction.

NCT ID: NCT04868721 Completed - Clinical trials for Bimaxillary Protrusion

Evaluation of Two Approaches of Micro-osteoperforations (MOPs) During Orthodontic Canine Retraction

Start date: November 11, 2020
Phase: N/A
Study type: Interventional

The aim of this clinical prospective study will be directed to evaluate two approaches of micro-osteoperforations (MOPs) during orthodontic canine retraction.
