NCT07210762

Brief Summary

The goal of this split-mouth randomized controlled trial is to assess whether the timing of extraction space closure-early vs. delayed initiation-affects the incidence of gingival cleft development in orthodontic patients. The main question it aims to answer is: Does the incidence of gingival cleft development get influenced by the specific time point at which orthodontic space closure is initiated following extraction? Quadrants will be assigned to the early movement group and the other to the delayed movement group and extractions will be performed accordingly. These will be assessed for the effect on development of gingival cleft development.

Outcome Measures

Primary Outcomes (1)

  • presence of gingival clefts after space closure initiation

    The primary outcome will be the presence of gingival clefts, which will be measured at 3 months and 6 months after space closure initiation

    start of canine retraction to its completion (approximately 6 months)

Secondary Outcomes (4)

  • craniofacial growth pattern

    craniofacial growth pattern will be measured at baseline

  • gingival biotype

    At baseline (immediately prior to tooth extraction)

  • buccal bone dehiscence

    Immediately post extraction

  • canine bulbosity

    will be measured at baseline

Study Arms (2)

Early movement group

EXPERIMENTAL

Canine retraction will be started 1 week after extraction

Other: Early space closure

Delayed Movement

EXPERIMENTAL

Canine retraction will be started 8 weeks after extraction

Other: Delayed space closure

Interventions

Space closure will be started 1 week after extraction

Early movement group

Space closure will be started 8 weeks after extraction

Delayed Movement
