The PhysioDynamicSystem (PDS) developed by Dr Ronald M Roncone focuses on six steps, which, when implemented accordingly, mean the PDS treatment concept has more than just an excellent functional and aesthetic outcome. What’s more, the duration of multi-band treatment is significantly reduced. One of these elementary steps is the use of the PDS Prescription. An extensive range of archwires is used in addition to interactive bracket systems (BioQuick® and QuicKlear® III). Whether they’re round or rectangular, made of titanol SE universal or beta-titanium, or come with or without a pre-loop – there’s a perfect archwire available for each stage of treatment.
