Kieferorthopädische Therapie im parodontal reduzierten Gebiss

Die Abwesenheit evidenzbasierter Therapiekonzepte macht die kieferorthopädische Behandlung parodontal Erkrankter zu einer großen Herausforderung für die kieferorthopädische Praxis. Der Verlust von parodontalem Attachment verändert die biomechanischen Voraussetzungen einer geplanten kieferorthopädischen Zahnbewegung. Die Simulation von Zahnbewegung an Modellen mit reduziertem Attachment mittels Finite-Elemente-Methode (FEM) würde die Therapie vorhersagbarer machen. In dieser Arbeit wird ein solches FEM-Modell vorgestellt, dass eine intrusive Zahnbewegung oberer Frontzähne simuliert und einem gesunden Modell gegenübergestellt.

Due to the absence of evidence based concepts for the therapy of periodontal reduced patients the therapy of such patients is a challenge for the orthodontic team. Attachment loss modifies the biomechanical features and must be considered in the treatment plan. The simulation of tooth movement in Finite-Element-Method models with reduced periodontal support would make the treatment more predictable. In this article we present such a model, simulating an intrusive tooth movement and compare it to a periodontal healthy model.
