NCT04950829

Brief Summary

Patients who have severe crowding on the upper jaw that requires two first premolars extraction will be enrolled in this trial. The different types of brackets, such as self-ligating brackets and conventional brackets, and the various acceleration methods, such as corticotomy, have different effects on the orthodontic treatment time and the periodontal tissues. So, this study will assess and compare the overall leveling and aligning time and the changes in periodontal indices between patients with severe crowding, treating with self-ligating brackets associated with flapless corticotomy versus conventional brackets alone versus self-ligating brackets alone. There are three groups: The first group (control group): the patients in this group will be treated using conventional brackets alone. The second group (Experimental group): the patients in this group will be treated using self-ligating brackets alone. The third group (Experimental group): the patients in this group will be treated using self-ligating brackets associated with flapless corticotomy.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Duration of teeth alignment

    The number of days required to finish the alignment stage of upper teeth will be calculated from the beginning of treatment till the end of the alignment stage (i.e. teeth alignment is achieved)

    This will be measured immediately at the end of the alignment stage; this is expected to be within 180 to 200 days

Secondary Outcomes (4)

  • The change in the plaque index.

    T0: immediately before applying the fixed appliance; T1: after 1 month; T2: after 2 months, T3: after 3 months, T4: after 6 months

  • The change in the gingival index

    T0: immediately before applying the fixed appliance; T1: after 1 month; T2: after 2 months, T3: after 3 months, T4: after 6 months

  • The change in papillary bleeding index.

    T0: immediately before applying the fixed appliance; T1: after 1 month; T2: after 2 months, T3: after 3 months, T4: after 6 months

  • The change in the probing depth

    T0: immediately before applying the fixed appliance; T1: after 1 month; T2: after 2 months, T3: after 3 months, T4: after 6 months

Study Arms (3)

Conventional brackets

ACTIVE COMPARATOR

Patients will receive an orthodontic treatment using conventional brackets until achieving appropriate alignment of the upper anterior teeth.

Device: Conventional brackets

Self-ligating brackets

EXPERIMENTAL

Patients will receive an orthodontic treatment using self-ligating brackets until achieving appropriate alignment of the upper anterior teeth.

Device: Self-ligating brackets

3- Self-Ligating brackets with fapless corticotomy

EXPERIMENTAL

Patients will receive an orthodontic treatment using self-ligating brackets with corticotomy until achieving appropriate alignment of the upper anterior teeth.

Procedure: Self-Ligating Brackets with flapless corticotomy

Interventions

These brackets are used in a conventional way, where the orthodontist used to apply elastic parts to engage the arch to the slot of the brackets.

Conventional brackets

These brackets do not need to use elastic parts to engage the arch to the brackets. The orthodontist can use sliding caps to open and close the slots of these brackets.

Self-ligating brackets

These brackets do not need to use elastic parts to engage the arch to the brackets. The orthodontist can use sliding caps to open and close the slots of these brackets. Flapless corticotomy will be performed in order to stimulate acceleration in tooth movement during the orthodontic treatment in this group only.

Eligibility Criteria

Age17 Years - 25 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Sever crowding greater than 6 mm on the upper jaw in which orthodontic treatment requires extraction of two upper premolars.
  • The Little's Index of Irregularity is more than 7 mm.
  • Good oral health (plaque Index is less or equal to 1).
  • Class I or class II (ANB ≤ 5) or class III (ANB ≥ 0).
  • Overbite is between 0-4 mm.
  • No skeletal constriction on the upper jaw.
  • No congenitally missing or extracted teeth (except for the third molars).

You may not qualify if:

  • Any systemic diseases affect teeth movement.
  • Any congenital syndromes or cleft lip and palate.
  • Bad oral health.
  • The patient is not committed to periodic follow-up times.
