Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will be done to compare the effectiveness of using coaxial tubular superelastic nickel-titanium and copper-nickel-titanium archwires during the initial phase of orthodontic treatment regarding alignment efficiency, pain perception, and root resorption.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This will be a prospective blinded non-stratified randomized clinical trial , parallel group trial with equal randomization (1:1 allocation ratio), different private clinics and general hospitals will allocate patients for this trial. The patients will be initially assessed for eligibility to be included in the study by the investigator. Those who will meet the inclusion criteria will be informed about the nature of the study verbally to take the initial approval for participation. The patients were asked to read the patient information sheet carefully at home and inform the investigator about their decision of participation at the subsequent appointment and to sign consent form sheet in case of agreement.

The patients will be treated using MBT prescription brackets with 0.022-inch slot (Pinnacle®, Ortho Technology, USA). Initially, teeth polishing will be performed with pumice and rubber cup, followed by water rinsing and air drying

All the participants will receive the same treatment. At the day of bonding, the first archwire will be placed for each group. Eight weeks later it will be replaced by the next size archwire for another eight weeks. Archwires will be tied to the bracket using elastomeric ligatures. Any debonding during treatment should be considered an emergency and re-bonded within 24 hours, otherwise the case will be dropout. A good alginate impression for the lower arch should be taken pre-treatment and after 4, 8, 12 and 16 weeks and a stone study model is obtained. Periapical X-ray for the mandibular central incisors will be taken pre-treatment and after 16 weeks. The participants will be given visual analog scale to record their pain p during the first week after each archwire placement.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The patients will be treated with straight wire appliance using MBT prescription brackets with 0.022-inch slot (Pinnacle®, Ortho Technology, USA). Initially, teeth polishing will be performed with pumice and rubber cup, followed by water rinsing and air drying

Archwire sequence for each group will be as follows:

1. Coaxial tubular superelastic nickel-titanium Group (TuNT) (Speed tubular supercable, Speed System™ Orthodontics, Ontario, Canada):

* 0.016-inch
* 0.018-inch
2. Copper-nickel-titanium Group (CuNT) (Damon Optimal-Force Copper Ni-Ti®, Ormco, Glendora, Calif):

* 0.014-inch
* 0.018-inch Allocation Concealment: This will be achieved using sequentially numbered, opaque and sealed envelopes which will be numbered according to the study numbers. Each envelope includes the treatment allocation card (group 1 or 2) and the related archwires.
Primary Study Purpose

TREATMENT

Blinding Strategy

TRIPLE

Participants Investigators Outcome Assessors
Sequence Generation: A computer random generator will be used to develop a simple randomization with an equal allocation ratio (1:1) and without stratification.

Allocation Concealment: This will be achieved using sequentially numbered, opaque and sealed envelopes which will be numbered according to the study numbers. Each envelope includes the treatment allocation card (group 1 or 2) and the related archwires.

Blinding As the study will be conducted in different clinics, all data collection and measurement will be completed with the investigator being masked to the allocation groups, though blinding of the operator will not be possible during the archwire placement.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Coaxial tubular superelastic nickel-titanium Group (TuNT)

0.016-inch coaxial tubular superelastic nickel-titanium archwire (TuNT) (Speed tubular supercable, Speed System™ Orthodontics, Ontario, Canada) will be placed in mandibular arch at the day of bonding. Eight weeks later it will be replaced by the 0.018-inch archwire for another eight weeks

Group Type EXPERIMENTAL

aligning archwires

Intervention Type OTHER

At the day of bonding, 0.016-inch archwire will be placed for the TuNT group. Eight weeks later it will be replaced by the 0.018-inch archwire for another eight weeks. While, for the CuNT group, 0.014-inch archwire will be placed at the day of bonding and eight weeks later it will be replaced by the 0.018-inch archwire for another eight weeks. Archwires will be tied to the bracket by elastomeric modules which will be changed every 4 weeks. A good-quality alginate impression for the lower arch should be taken pre-treatment and after 4, 8, 12 and 16 weeks and a stone study model is obtained. Periapical X-ray for the mandibular central incisors will be taken pre-treatment and after 16 weeks. The participants will be provided by a visual analog scale (0-10) to record their pain perception during the first week after each wire placement.

Copper-nickel-titanium Group (CuNT)

0.014-inch Copper-nickel-titanium archwire (CuNT) (Damon Optimal-Force Copper Ni-Ti®, Ormco, Glendora, Calif) will be placed in mandibular arch at the day of bonding. Eight weeks later it will be replaced by the 0.018-inch archwire for another eight weeks.
