Einordnung ankylosierter Zähne im digitalen Zeitalter

Zusammenfassung

Ankylosierte Zähne sind eine große Herausforderung im Rahmen einer kieferorthopädischen Behandlung. Neben der Extraktion, der Transplantation, dem konventionellen Einordnungsversuch nach Lockerung, sowie der ossären Distraktion stellt die parodontale Distraktion (PDL-Distraktion) eine sehr effektive Methode zur Einordnung ankylosierter Zähne dar. Auch bei unsicherer langfristiger Prognose von Zähnen mit Defekten kann mittels PDL-Distraktion Knochen sowie Weichgewebe in der oft defizitären Region generiert werden. Neue CAD-CAM-Techniken wie Insertionsguides und Metalldruck mittels Lasersintering optimieren das Verfahren der PDL-Distraktion.

Abstract

Ankylosed teeth are a major challenge in orthodontic treatment. In addition to extraction, transplantation, conventional alignment after tooth loosening, and osseous distraction, periodontal distraction (PDL distraction) is a very effective method for aligning ankylosed teeth. Even when the long-term prognosis of deficient teeth is uncertain, PDL distraction can be used to generate bone as well as soft tissue in the often deficient region. New CAD-CAM techniques such as insertion guides and metal printing by laser sintering optimize the PDL distraction procedure.
