The influence of occlusal forces on force delivery properties of aligners during rotation of an upper central incisor.

Objective: To determine the forces and moments delivered to a maxillary central incisor during rotation with aligners when a simulated occlusal force generated during swallowing acts on the appliance.

Materials And Methods: Five identical appliances were manufactured from four different starting materials (Erkodur 0.8 mm and 1.

Initial forces and moments delivered by removable thermoplastic appliances during rotation of an upper central incisor.

Objective: To determine the forces and moments delivered to a maxillary central incisor during rotation by three different thermoplastic appliances with identical thickness.

Materials And Methods: Five identical appliances were manufactured from each of three materials (Ideal Clear 1.0 mm, Erkodur 1.
