Abstract:

Treatment outcome and duration of 2 different treatment approaches in 2 groups of comparable extraction cases were analyzed: Group I: serial extraction performed in the early mixed dentition followed by orthodontic treatment in the permanent dentition; group II: extractions as well as orthodontic treatment in the permanent dentition.

The following conclusions were reached: 1. The treatment period with fixed appliances was highly significantly shorter in group I; however, the number of appointments was significantly higher and the total duration of treatment/observation time significantly longer. 2. In both groups the reduction in PAR score was either improved or greatly improved in all cases.

Zusammenfassung:

Behandlungsergebnis und -dauer bei zwei unterschiedlichen Behandlungsansätzen in zwei Gruppen vergleichbarer Extraktionsfälle wurden untersucht: Gruppe I: Serienextraktion, eingeleitet im frühen Wechselgebiss, gefolgt von einer kieferorthopädischen Behandlung im bleibenden Gebiss; Gruppe II: Extraktionen und Behandlung im bleibenden Gebiss.

Folgende Schlussfolgerungen konnten gezogen werden: 1. Die Behandlungsdauer mit festsitzenden Geräten war in Gruppe I hochsignifikant kürzer, jedoch waren die Zahl der Termine und die Gesamtdauer von Beobachtungs- und Behandlungszeit signifikant länger. 2. In beiden Gruppen konnte der PAR-Wert bei allen Patienten im Laufe der Behandlung so weit reduziert werden, dass sich am Behandlungsende eine Einstufung in die Kategorien “verbessert” oder “wesentlich verbessert” ergab.
