Force system generated by elastic archwires with vertical V bends: a three-dimensional analysis.

ABSTRACT:

Background

Our previous understanding of V-bend mechanics is primarily from two-dimensional (2D) analysis of archwire bracket interactions in the second order. These analyses do not take into consideration the three-dimensional (3D) nature of orthodontic appliances involving the third order.

Objective

To quantify the force system generated in a 3D two bracket set up involving the molar and incisors with vertical V-bends.

Materials and methods

Maxillary molar and incisor brackets were arranged in a dental arch form and attached to load cells capable of measuring forces and moments in all three planes (x, y, and z) of space. Symmetrical V-bends (right and left sides) were placed at 11 different locations along rectangular beta-titanium archwires of various sizes at an a
