Behandlungsmöglichkeiten bei Nichtanlagen der lateralen Inzisivi – eine Literaturübersicht

Zusammenfassung

In der Kieferorthopädie ist man häufig mit Patienten mit Agenesien konfrontiert. Der obere seitliche Schneidezahn ist der am zweithäufigsten fehlende Zahn. Es gibt 3 Therapieoptionen, um den fehlenden Schneidezahn zu ersetzen. Dazu gehört der Lückenschluss mit Ersatz des seitlichen Schneidzahnes durch den Eckzahn und die Lückenöffnung mit implantat- oder zahngetragener Versorgung. Zahlreiche Faktoren wie bspw. die Malokklusion, das Ausmaß des Crowdings, das Profil, die Lachlinie und die Form und Farbe der Eckzähne, spielen eine entscheidende Rolle bei der Therapieentscheidung. Der vorliegende Artikel beschäftigt sich mit den Vorteilen und Nachteilen von kieferorthopädischem Lückenschluss und der Lückenöffnung.

Abstract

Orthodontists often encounter patients with missing teeth. The maxillary lateral incisor is the second most common congenitally absent tooth. There are 3 treatment options for replacing missing lateral incisors. They include canine substitution, a tooth-supported restoration or a single-tooth implant. Managing patients with congenitally missing maxillary lateral incisors raises several important issues involving type of malocclusion, amount of space, profile, smile line, as well as shape and color of the canines. The present article will discuss advantages and disadvantages for orthodontic space closure and also for space opening.
