Korrektur des offenen Bisses mithilfe von Mini-Implantat gestützter Molarenintrusion

Zusammenfassung

Einleitung Der Artikel beschreibt die Korrektur skelettal offener Bisse geringgradiger bis moderater Ausprägung mithilfe der Molarenintrusion im Oberkiefer als Verfahren der indirekten Bissvertiefung.

Material und Methode Anhand von 2 Kasuisitiken werden die eingesetzten Intrusionsmechaniken und die klinischen Vorgehensweisen detailliert beschrieben. Die Verankerung erfolgte mit Mini-Implantaten im anterioren Gaumen.

Ergebnisse Die Korrektur der offenen Bisse erfolgte primär durch die Molarenintrusion und die folgende Autorotation der Mandibula. Bei den vorliegenden Fällen zeigte sich 2 Jahre nach der aktiven Behandlung eine stabile Korrektur des offenen Bisses.

Schlussfolgerung Die Korrektur des skelettal offenen Bisses mithilfe einer durch Mini-Implantat gestützten Mechanik stellt bei geringen und moderaten Ausprägungen eine Alternative zur kombiniert kieferorthopädisch-kieferchirugischen Therapie dar. Aufgrund des zu erwartenden Relapses der Molarenintrusion erscheint eine Überkorrektur sowie eine effektive Retentionsstrategie wünschenswert.

Abstract

Introduction The article describes skeletal open bite corrections of minor and moderate severity with the help of maxillary molar intrusion as a method of indirect bite deepening.

Material and methods Two case reports are used to describe in detail the applied intrusion mechanisms and clinical procedures. Anchoring was performed with mini-implants in the anterior palate.

Results Correction of the open bite was primarily performed by molar intrusion and subsequent autorotation of the mandible. Two years after active treatment the correction of the open bite was observed to be stable.

Conclusion Correction of the skeletal open bite with mini-implant supported mechanics represents an alternative to combined orthodontic and maxillofacial surgery for minor and moderate manifestations. Due to the expected relapse after molar intrusion, overcorrection and an effective retention strategy seem desirable.
