Recruit Status: Recruiting
Study Type: Interventional

Official Title: The Effect of Two Different Force Magnitudes on Maxillary Posterior Segment Intrusion in Adult Patients With Skeletal Open Bite Using Temporary Anchorage Devices- A Random

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

Detailed Summary: This randomized controlled trial is aiming to study the effect of the different force magnitude on maxillary posterior segment intrusion. Two groups are going to be allocated and the amount and rate of intrusion will be measured and compared.
Sponsor: Cairo University

Current Primary Outcome:

• Amount of intrusion [ Time Frame: 6 months ]
  The amount the upper posterior teeth have been intruded.
• Rate of bite closure [ Time Frame: 6 months ]
  The rate by which the open bite closes as a result of posterior segment intrusion

Original Primary Outcome: Same as current

Current Secondary Outcome:

• Average rate of intrusion [ Time Frame: 6 months ]
  The amount of intrusion divided by the duration of intrusion
• Root resorption [ Time Frame: 6 months ]
  The amount of root resorption as a result of the intrusive force
• Tipping [ Time Frame: 6 months ]
  The amount of mesiodistal and buccolingual tipping of posterior teeth

Original Secondary Outcome: Same as current
