Study summary

To evaluate the effect of selective micro-osteoperforations (MOPs) on the amount of distal movement of the upper canine, the mesio-distal inclination of the canine and the messiah movement of the upper first molar.

Methods: Clinical trial with Split mouth design in 35 orthodontic patients with bilateral extraction of the upper first premolar, each upper canine will be randomly assigned to the intervention (MOP) or to the control side. Participants will be followed for 3 months and the investigators will take periapical radiographs, cast models and clinical measurements before and after canine retraction. The measurements will be taken by previously calibrated operators. The results are going to be determined and compared between sides, with the corresponding statistical tests and the results are going to be analyzed.

Read the detailed description

PICO QUESTION: ¿Does the amount of distal orthodontic movement of the upper canine increase in the side with MOPs compared with the side without MOPs? Population: Orthodontic patients with bilateral extraction of the upper first premolar (Split mouth design trial) Intervention: Distal movement of the upper canine with Selective MOPs (distal to canine) in one hemi-arch Comparison: Distal movement of the upper canine without MOPs in the other hemi-arch Outcome: Canine and first molar movements

GENERAL AIM:

  • To evaluate the effect of selective micro-osteoperforations (MOPs) on the amount of distal movement of the upper canine, the M-D inclination of the canine and the mesial movement of the upper first molar.

METHODS

OVERVIEW OF DESIGN Study Design: Randomized controlled clinical trial in split mouth design.

  • Randomly assign upper canines in to 2 sides in a split mouth design study: one side to receive intervention (MOPs) and the other side as a control (without MOPs).
  • Then follow both sides for three months
  • Split mouth design method: The investigators are going to randomly assign to the patients' left or right sides, one side for the intervention and the other side for the control (to eliminate the possibility of selection bias).
  • Blinding: It is not possible to blind participants and clinical staff, but the investigators are going to blind the operators who will perform the measurements and the data analysis (single-blinded).

The participants will be with orthodontic fixed appliances (MBT prescription slot 0.022 "x0.028", canine torque 0 °), with working arches 0.019 "x0.025" stainless steel and with bilateral extractions of the first upper premolars for 6 months or more. For this moment the crowding must be resolved and there must be a space of 3 or more millimeters between the canines and second premolars.

The 4 upper incisors will be consolidated with a 0.010 "stainless steel ligature below the arch to prevent opening of anterior spaces.

Observation:

  • No transpalatal arch (TPA) will be used in any of the participants
  • It is going to place a mini-implant in the palate for reference point before the start of the experiment PLANS FOR RECRUITMENT Patients of the Clinic University (UniCIEO) and Antioquia University POTENCIAL CONFOUNDING VARIABLES

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Study arms

  • Experimental
    Micro-osteoperforations (MOPs)

    Canine Distalization with micro-osteoperforations at the start of the distalization Distalization of the upper canine in working phase with coil spring of 100 gr of force

    Procedure: micro-osteoperforations (MOPs)

Interventions

  • Proceduremicro-osteoperforations (MOPs)

    three (3) micro-osteoperforations (MOPs) in the cortical and medullar bone, distal to the upper canine. These MOPs will be at the apical, medial and gingival zone of the bone located at the distal surface of the canine in the buccal and in the palatal side. The deep of the MOPs will be at 6 mm. It is going to be done with a PROPEL

What researchers measure

Primary outcomes

  1. Amount of distal movement of the upper canine

    Distance from a tangent to a reference point in the palate (third palatal ruga) to the distal side of the upper canine (measured in digital models)

    Time frame: Change from baseline at three months

  2. Inclination of the upper canine, second premolar and first molar

    The angle between the long axis of the clinical crown and the reference plane the occlusal plane.(measured in digital models)

    Time frame: Change from baseline at three months

  3. Angulation of the upper canine, second premolar and first molar

    The long axis of the posterior buccal surface is going to be measured relative to the occlusal plane (measured in digital models)

    Time frame: Change from baseline at three months

  4. Amount of mesial movement of upper first molar

    Distance from a tangent to a reference point in the palate (third palatal ruga) to the mesial side of the upper first molar (measured in digital models)

    Time frame: Change from baseline at three months

Secondary outcomes

  1. Periodontal status

    It's going to be measured by clinical exam

    Time frame: Change from baseline at three months

  2. Evaluation of the perception of pain by the patient: VAS

    Pain visual analogue scale (AVS) - from 0 to 10 points, Higher values represent more pain perception by the participant

    Time frame: Change from baseline at three months

  3. Number of participants with postoperative inflammation and/or infection

    Inflammation, infection by clinical exam

    Time frame: Change from baseline at three months

  4. Number of upper canines with external root resorption

    Periapical radiograph

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 12, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
