Özet

Introduction: This report aims to present case series to describe a treatment protocol for correction of severe open bite in non-growing patients Methodology: Patients diagnosed with skeletal open bite malocclusion (overbite range: -3 to -6 mm) were treated using a bonded appliance and skeletal anchorage. Intrusive force was applied between buccal bars of appliance and zygomatic multipurpose implants (MPI). Intrusion was continued until positive overbite occurred. Treatment progressed with conventional fixed orthodontic treatment for alignment and settling. MPIs were retained until the end of treatment for retention of intrusion Results: Clinically effective open bite correction was achieved by intrusion of maxillary buccal segment and mandibular counterclockwise autorotation Conclusion: This protocol includes zygomatic anchorage and an appliance that aims triple intrusion effect through combination of orthodontic and physiological forces. Achieving significant maxillary intrusion, controlling mandibular eruption and maximizing mandibular counterclockwise autorotation are the main outcomes of this protocol.
