NCT03876184

Brief Summary

This study investigates the efficiency of orthodontic aesthetic archwires which are coated with tooth-colored materials and the durability of the coatings after being used. Theoretically, the coatings provide excellent aesthetics throughout treatment and faster tooth alignment. However, from our clinical experience, these claims are the opposite. Cracks and ruptures as well as archwire fractures have been noted. Therefore, it is presumed that the aesthetic archwires may not be any different from the conventional uncoated archwires.

Outcome Measures

Primary Outcomes (1)

  • Alignment efficiency

    The tooth irregularity between pre- and post-experiment dental casts are measured in millimetres. The difference between the two measurement will be calculated in percentage.

    8 weeks

Secondary Outcomes (3)

  • Coating loss

    8 weeks

  • Color change

    8 weeks

  • Participant perception towards aesthetic archwires

    8 weeks

Study Arms (4)

RMO FLi® Tooth-coloured superelastic Nickel Titanium

EXPERIMENTAL

This group has been allocated with upper and lower round 0.014" RMO FLi® Tooth-coloured superelastic Nickel Titanium aesthetic archwires for a duration of 8 weeks.

Other: Aesthetic archwires

G&H G4 Tooth-coloured superelastic Nickel Titanium

EXPERIMENTAL

This group has been allocated with upper and lower round 0.014" G\&H G4 Tooth-coloured superelastic Nickel Titanium aesthetic archwires for a duration of 8 weeks.

Other: Aesthetic archwires

Orthocare Euroform® Cosmetic Tooth-coloured superelastic Nickel Titanium

EXPERIMENTAL

This group has been allocated with upper and lower round 0.014" Orthocare Euroform® Cosmetic Tooth-coloured superelastic Nickel Titanium aesthetic archwires for a duration of 8 weeks.

Other: Aesthetic archwires

Conventional superelastic Nickel Titanium

ACTIVE COMPARATOR

This group has been allocated with conventional upper and lower round 0.014" superelastic Nickel Titanium archwires for a duration of 8 weeks.

Other: Control group

Interventions

During bond-up, randomly allocated envelope will be opened and archwires will be ligated with elastomeric ligatures.After 4 weeks,the same archwires will be retied.Any fractured archwire will be recorded and discarded.The fractured wire will be replaced with conventional archwire and treatment continues.On the 2nd follow-up (at 8th week), the tested wires are collected, disinfected, dried and placed back in the allocated envelope.Upper and lower impressions will be taken.Questionnaires will be answered by participants.The trial ends and treatment continues as planned.Fractured archwire will be recorded and discarded.

Masking Details
The participants will select only one sealed envelope containing the archwires which has been labelled and coded without looking at other archwires. Both operators and participants are not informed of the brands of the coated archwires. The statistician will analyse the data based on the assigned codes. The codes will be broken by the principal investigator after the results have been produced.
