Zusammenfassung
Die kieferorthopädische Therapie sollte bezüglich der medizinischen als auch der wirtschaftlichen
Komponenten stets eine bestmögliche, effektive und effiziente Behandlung als Ziel
haben. Selbstligierende Bracket-Systeme tragen zur Realisierung derartiger Behandlungskonzepte
bei. Durch selbstligierende Bracket-Systeme ist es möglich, Zahnbewegungen friktionsärmer
durchzuführen, kleine Kräfte zur Minimierung der Wurzelresorptionsgefahr anzuwenden,
eine gute Mundhygienemöglichkeit mit geringem Demineralisierungsrisiko durch ein kleines
Bracketdesign zu gewährleisten und den Patientenkomfort durch das Vermeiden von häufig
störenden Metalligaturen zu steigern. Es zeigt sich ferner, dass durch die Verwendung
dieser Bracket-Systeme eine Reduktion der Behandlungszeit beim Bogenwechsel um die
Hälfte pro Behandlungssitzung erreicht werden kann. Aufgrund der in das Bracket integrierten
Verschlussklappe ist ein schnelles Verschließen des Brackets ohne zeitaufwendiges
Einligieren mit konventionellen metallischen oder elastischen Ligaturen möglich.
Ziel der folgenden Arbeit ist es, das Design und die Verwendung des selbstligierenden
In-Ovation-Bracketsystems zu beschreiben, klinische und biomechanische Aspekte zu
betrachten, sowie Fragen der Effektivität und Effizienz zu beantworten.
Abstract
Orthodontic treatment can become significantly more efficient by reducing antiquated
elastomer and metal ligature tieing. Interactive self-ligating appliances have the
potential to improve poor oral hygiene, decalcification, heavy forces, root resorption,
and interbracket rigidity with rectangular arch wires. The improvements can be clinically
significant. By using these appliances arch wire changes have shown to take half the
time at each appointment. The interactive self-ligating system has most importantly
been established as a fully pre-programmed Siamese Twin.
Repetitive replacement of time-consuming elastomers and metal ties has been replaced
by a rapidly acting, resilient clip built into the bracket body.
The aim of this paper is to explain the design and the biomechanic effects as well
as the clinical advantages of the Siamese Twin IN-OVATION bracket system.
