Clinical Trial Summary

Compare between bi-maxillary (maxillary and mandibular) posterior dento-alveolar intrusion and maxillary posterior dento-alveolar intrusion as regards open bite closure.

Description:

Now, maxillary posterior dento-alveolar intrusion has been validated as a conservative treatment modality for treatment of skeletal open bite in adult patients. However, it was proved that mandibular posterior teeth extrusion take place during the treatment which results in reduction in the amount of open. bite closure. Therefore, the aim of our study is to compare in a randomized clinical trial methodology between maxillary posterior dento-alveolar intrusion and combined maxillary and mandibular posterior dento-alveolar intrusion in terms of anterior open bite closure.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Anterior open bite closure	The amount of overbite gained as a result of posterior dento-alveolar intrusion	6 months
Secondary	Maxillary posterior teeth intrusion radiographically in millimeters.	The distance travelled by maxillary premolars and molars of the right and left sides to a reference plane	6 months
Secondary	Mandibular posterior teeth intrusion radiographically in millimeters.	The distance travelled by mandibular premolars and molars of the right and left sides to a reference plane	6 months
Secondary	Tip and torque of intruded teeth radiographically in degrees.	• Torque change is measured as the change in the angle between the long axis of the intruded teeth and the FH plane (for tip) mid-sagittal plane (for torque).	6 months
