A finite element study comparing Advansync® and Twin Block in mandibular anterior repositioning.

Objective: This study aims to utilize the finite element method (FEM) to compare the dentoalveolar and mandibular effects associated with anterior mandibular repositioning using AdvanSync® (ADV) and Twin Block (TB).

Methods: A patient with Class II skeletal malocclusion and mandibular retrognathism was selected. A TB appliance was subsequently applied.
