A modification to the standard quadhelix transpalatal expansion arch is presented in which the wire passes distal to the most posterior molar and enters the mesial end of the headgear tube. Laboratory measurements were carried out on small, average a

The theoretical prediction of the onset of distortion within a retraction U-loop as derived from a knowledge of the maximum bending moment, the wire characteristics and the loop dimensions was found to be in good agreement with the experimental measu

Friction in fixed appliance systems has received considerable attention in the recent literature, although that attributable to the type of ligation used has not been fully investigated. This in vitro study of 0.022 × 0.028 inch slot Minitwin, Activ

The force system operating between bracket and wire in sliding mechanics has been examined analytically using simple beam theory with the object of providing further information on the cause of bracket binding. The results were checked on an enlarged

Superelastic nickel-titanium archwires, unlike conventional wires, are capable of withstanding very large deflections and on returning to their original shape on deactivation will produce more moderate forces. The region over which there is a 'platea

The characteristics of the Ricketts maxillary canine retraction spring (Ricketts, 1974) have been derived using the complementary (strain) energy method. The theoretical predictions of the analysis have been confirmed by experiments on large planar m

Friction in fixed appliance systems has received considerable attention in recent literature, although that attributable to varying second order (tip) and third order (torque) adjustments in either the bracket or the archwire has not been fully inves

Intra-batch variation in the load-deflection characteristics of 13 superalloy nickel-titanium wires has been examined at nominal mouth temperature (35 degrees C). The results indicate that although most of the superalloy nickel-titanium wires were un

A logical basis for the sequence of wires chosen during orthodontic treatment with fixed appliances is presented. This utilizes a new more realistic model for the radial deflection of a segment of the archwire in which the wire is restrained by the l
