Die Retention ist die Phase der kieferorthop dischen Behandlung, die die Z hne nach Beendigung der aktiven kieferorthop dischen Zahnbewegung in ihrer kieferorthop disch korrigierten Position h lt. Kieferorthop dische Retainer widerstehen der Tendenz der Z hne, unter dem Einfluss von Parodontal-, Okklusal- und Weichteilkr ften und anhaltendem dentofacialen Wachstum in ihre Vorbehandlungsposition zur ckzukehren. Nur sehr wenige prospektiv kontrollierte Studien haben die Wirksamkeit der Retention bewertet. Dar ber hinaus ist sehr wenig ber die Wahrnehmung des Patienten in Bezug auf einen kieferorthop dischen R ckfall bekannt. Verschiedene Studien haben gezeigt, dass feste Retention, die nur an Eckz hne gebunden ist, einen R ckfall hat, w hrend andere gezeigt haben, dass ein R ckfall zwar vorliegt, aber nicht signifikant oder klinisch relevant ist. Dieses Buch fasst jeden Aspekt von R ckfall und Retention zusammen.

La ritenzione la fase del trattamento ortodontico che mantiene i denti nelle loro posizioni corrette ortodonticamente dopo la cessazione del movimento ortodontico attivo dei denti. I mantenitori ortodontici resistono alla tendenza dei denti a ritornare alle posizioni di pretrattamento sotto l'influenza delle forze parodontali, occlusali e dei tessuti molli e della continua crescita dento-facciale. Pochissimi studi prospettici controllati hanno valutato l'efficacia della ritenzione. Inoltre, si sa molto poco sulla percezione del paziente in relazione alla recidiva ortodontica. Diversi studi hanno dimostrato che la ritenzione fissa legata solo ai canini ha ricaduta, mentre altri hanno dimostrato che anche se esiste una ricaduta, essa non significativa o clinicamente rilevante. Questo libro riassume ogni aspetto della recidiva e della ritenzione.
