Arco recto de baja fricciónsistema Synergy (1. ª parte)

Abstract

Straight wire low friction (SWLF) represent the latest generation of straight wire technique and it is based on the concept of selective friction control (CSF) which tries to overcome the problems arising from the static and kinetic friction which occurs in the SW techniques using with traditional brackets. The SWLF is a diagnostic and therapeutic upgrade in accordance with the latest technological advances in our specialty ( orthodontic practice), and combines the use of Synergy low friction brackets (RMO), superelastics and thermoelastics latest generation wires, beta III-titanium finishing wires, hooks and elastic modules to close spaces and microscrews as a means oh bone anchorage. The special design of the Synergy bracket, the new prescription SWLF and the latest generation wires facilitate easier alignment, allows the rapid rectangular arch wire fit and better wire-slot interaction. The new arch wires with their wide range of action allow us to space out patient appointments and reduce the treatment time which uses fixed apparatus. Selective friction control (CSF) is established according to the following criteria: wire selection, ligature (composition, type and design) and the placement and control hooks (crimpable-hook) which may be placement in any arch with special pliers. The technique has a series of diagnostic and therapeutic protocols and includes a clear archwires selection policy. The general philosophy of the technique is to standardize our treatments, simplifying biomechanical aspects and optimizing the biological tooth movement by appling continius and long lasting light forces. The SWLF is an attempt to bring orthodontic practice in line with the demands of patients, making shorter, faster and ergonomic treatment possible.
