Brief Summary

A Randomized clinical trial comparing two different force magnitudes in maxillary posterior segment intrusion in adult patients with skeletal open bite malocclusion

Conditions

Orthodontics

Keywords

skelatal open bite, posterior intrusion

Outcome Measures

Primary Outcomes (2)

• Amount of intrusion

  The amount the upper posterior teeth have been intruded.

  6 months

• Rate of bite closure

  The rate by which the open bite closes as a result of posterior segment intrusion

  6 months

Secondary Outcomes (3)

• Average rate of intrusion

  6 months

• Root resorption

  6 months

• Tipping

  6 months

Study Arms (2)

Intrusion by 200 g

ACTIVE COMPARATOR

Applying 200 g intrusive force for the maxillary posterior segment intrusion using miniscrews

Device: Intrusion by 400 g

Intrusion by 400 g

EXPERIMENTAL

Applying 400 g of Intrusive force for the maxillary posterior segment intrusion using miniscrews

Device: Intrusion by 400 g

Interventions

Intrusion by 400 g DEVICE

using miniscrews and coil springs to apply the intrusive force on maxillary posterior segment intrusion.

Intrusion by 200 g; Intrusion by 400 g

Eligibility Criteria

• Age: 15 Years - 25 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64)

You may qualify if:

• Adult patients with an age range from 17 to 25.
• Skeletal open bite.
• Dental open bite that is due to overgrowth of maxillary posterior segment as seen clinically and that can be corrected without surgical intervention (a minimum of 3 mm and a maximum of 8 mm).
• Skeletal class I or mild to moderate skeletal class II that enables camouflage treatment.
• Normal incisor show on smiling (that makes the case indicated for molar intrusion and not for incisor extrusion).
• Full set of maxillary posterior dentition (first and second premolars, first molars at least).
• No previous orthodontic treatment.

You may not qualify if:

• Medically compromised patients.
• Patients suffering from any congenital or hereditary diseases.
• Smoking or any systemic diseases.
• Chronic use of any medications including antibiotics, phenytoin, cyclosporin, anti-inflammatory drugs, systemic corticosteroids, and calcium channel blockers.
