Zusammenfassung:
Die Beeinflussung des Unterkieferwachstums durch funktionskieferorthopädische Geräte wird immer noch kontrovers diskutiert. Die meisten Arbeiten, die über positive Effekte von FKO-Apparaturen berichten, zeichnen sich durch eine mangelhafte wissenschaftliche Methodik aus. Daher sollte die Wirksamkeit der FKO-Geräte in erster Linie im Rahmen prospektiver randomisierter klinischer Studien überprüft werden. Nach bisherigem Kenntnisstand kann nicht davon ausgegangen werden, dass funktionskieferorthopädische Apparaturen das Unterkieferwachstum stimulieren und steigern können. Gelegentlich beobachtete positive Wachstumseffekte sind in aller Regel nicht substanziell und sind nicht stabil über einen längeren Zeitraum.
Summary
The mode of action of functional appliances, particularly in relation to stimulating mandibular growth, is a controversial subject. Many of the reports concerning growth effects of functional appliances have been characterized by poor methodology. In assessing functional appliances, results from prospective randomized clinical trials should be given prominence. On the basis of available evidence, it cannot be concluded that functional appliances are effective in stimulating and increasing mandibular growth in the long term. Although favourable growth changes have been reported following phase 1 therapy, they are generally not substantial and long term stability appears to be poor.
