• 1 other identifier: deepak sindhu
• Study Type: interventional
• Target: 14
• Locations: 0 countries
• Sites: N/A

Brief Summary

the aim of this study is to document the changes brought about in the internal anatomic relationships of the TMJ complex , positional changes of glenoid fossa with respect to adjacent cranial structures after completion of fixed orthodontic treatment in adolescent males initially treated with removable functional appliances for skeletal class II, Angle's class II division 2 malocclusion

Conditions

Class II Division 2 Malocclusion

Outcome Measures

Primary Outcomes (7)

• sagittal condyle concentricity

  measured in percentage displacement of condyle in the glenoid fossa

  12 months

• sagittal disc position

  measured in degrees from references from Frankfurt Horizontal plane and Posterior Condylar line.

  12 months

• Linear glenoid fossa displacement

  measured in millimetres, distance from external auditary meatus to centre of condylar head and Posterior glenoid spine

  12 months

• Superior joint space

  measured in millimetres, distance between most superior point on glenoid fossa and superiormost point on condyle

  12 months

• eminence angle

  measured in degrees, the angle of anterior slope of glenoid fossa in relation to Frankfurt Horizontal plane and Posterior Condylar line

  12 months

• Glenoid fossa angle

  measured in degrees, angle between anterior slope and posterior slope of glenoid fossa

  12 months

• coronal disc position

  relative position on the equal tenths on condyle. negative value representing lateral side and positive value indicating the medial side of the disc

  12 months
