[Control of the incisor axis in the vestibulo-lingual direction using an original titanium-molybdenum alloy arch]

In order to restore the vestibulo-lingual orientation of the incisor axis while controlling the position of the crowns, the author suggests using a simple original arch, compatible with any of the multi-clip technics used by orthodontists. This arch is made of Titanium-Molybdenum Alloy and presents the distinctive feature of being specially shaped, on the ribbon side, so as to be introduced edgewise. Practical ease, efficiency in obtaining large amplitude, precisely controlled movements, as well as accurate measurement of torque make of this instrument a practical tool for controlling the incisor axis in the vestibulo-lingual orientation, and for improving the I/i angle warranteeing the stability of the results. This arch can be used both in monodisciplinary and multidisciplinary orthodontics, more particularly in surgical-orthodontic management of retrognathia combined with traumatic supraclusion of incisors or with linguoversions of central upper teeth.
