NCT04383600 | Completed DMC

• 1 other identifier: 100
• Study Type: interventional
• Target: 12
• Locations: 1 country
• Sites: 1

Brief Summary

The aim of the present clinical study was directed to evaluate the effectiveness of micro-osteoperforations on the rate of canine retraction; in addition, the potential risk for root resorption during maxillary canine retraction.

Conditions

Dental Malocclusions; Angle Class II, Division 1; Bimaxillary Protrusion

Keywords

MOPs; micro-osteoperforation; acceleration; orthodontic tooth movement

Outcome Measures

Primary Outcomes (2)

• Rate of canine retraction

  Clinically, patients were evaluated immediately before canine retraction and every 4 weeks till complete space closure (complete canine retraction). It was based on measuring the distance between the contact points on the distal surface of the canines and the contact points on mesial surface of the second premolars.

  change from start of canine retraction until complete space closure up to 6 months

• Canine root length changes

  The CBCT scans were taken before orthodontic treatment and after complete space closure (canine retraction) to be analyzed for assessment of Canine root length changes. The root length was measured along the axis of the root, perpendicular to a line connecting the buccal and palatal cemento-enamel junction CEJ in sagittal view

  change from start of orthodontic treatment until complete space closure up to 9 months

Secondary Outcomes (1)

• Anchorage loss of maxillary first permanent molars.

  change from start of orthodontic treatment until complete space closure up to 9 months

Study Arms (2)

Conventional side

NO INTERVENTION

Canine retraction was commenced without micro-osteoperforations.

Mops side

EXPERIMENTAL

Canine retraction was commenced with micro-osteoperforations.

Procedure: Micro-osteoperforation

Interventions

Micro-osteoperforation PROCEDURE

three flapless micro-osteoperforations was performed distal to the maxillary canine before starting retraction.

Also known as: Mops

Eligibility Criteria

• Age: 14 Years - 18 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64)

You may qualify if:

• An age ranged between 14 to 18 years.
• Class II division 1 malocclusion or Class I bimaxillary protrusion with mild or no crowding. Wherever crowding was present, it was symmetrical on both sides of the arch.
• Patients who diagnosed to require extraction of at least maxillary first premolars bilaterally as a part of their treatment plan.
• Complete permanent dentition (3rdmolars were not included).
• Good oral and general health.
• No history of periodontal problems.
• No therapeutic intervention planned involving intermaxillary or other intraoral or extraoral appliances during the study period.

You may not qualify if:

• Blocked out or impacted maxillary canines.
• Transverse and/or vertical skeletal dysplasia or craniofacial anomalies.
• Systemic diseases or regular use of medications that could interfere with orthodontic treatment.
• Previous orthodontic treatment.
