About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Skeletal open bite with a dental open bite ranging from 3-8 mm.
  • Adequate incisal show at rest and on smiling
  • Full set of posterior teeth from first premolar to second molar (with the exception of one tooth in one quadrant).

Exclusion criteria

  • Dental open bites without skeletal components
  • Previous orthodontic treatment
  • Medically compromised patients

Treatment and study plan

Maxillary posterior dento-alveolar intrusion

Procedure

Mini-screw supported maxillary or bi-maxillary posterior dento-alveolar intrusion

Other names: Bi-maxillary posterior dento-alveolar intrusion

Primary outcomes

  1. Anterior open bite closure

    Time frame: 6 months

    The amount of overbite gained as a result of posterior dento-alveolar intrusion

Secondary outcomes

  1. Maxillary posterior teeth intrusion radiographically in millimeters.

    Time frame: 6 months

    The distance travelled by maxillary premolars and molars of the right and left sides to a reference plane

  2. Mandibular posterior teeth intrusion radiographically in millimeters.

    Time frame: 6 months

    The distance travelled by mandibular premolars and molars of the right and left sides to a reference plane

  3. Tip and torque of intruded teeth radiographically in degrees.

    Time frame: 6 months

    • 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).
