The Reversion Force of NiTi Orthodontic Wires in the Temperature
The interest in using the pseudoelastic properties of NiTi wires in orthodontic practice arises chiefly from the expectation that they can afford low continuous forces at constant temperature. The reversion force developed by NiTi archwires depends, however, upon temperature since the superelastic force follows a Clausius-Clapeyron like equation. Actually the oral environment temperature is mod...
متن کاملEffect of FluoTide Released from Orthodontic Wires Fluoride - containingDental Restoratives on NiTi
determined daily for 10 days. The morphology of wires was observed using a seanning electron microscope, After imrnersion for 10 days, the initial micrehardness of the wires deereased by O.3-5.6% depending on the test solution. Dyract AP (DA) and F2000 (F2) (compomers) released signifieantly more fluoride than the ether resin products (composite resins) regardless of the test solution, In pH 2,...
متن کاملDo Mechanical and Physicochemical Properties of Orthodontic NiTi Wires Remain Stable In Vivo?
Introduction and Aim. Exceptional properties of the NiTi archwires may be jeopardized by the oral cavity; thus its long-term effect on the mechanical and physiochemical properties of NiTi archwires was the aim of work. Material and Methods. Study group comprised sixty 0.016 × 0.022 NiTi archwires from the same manufacturer evaluated (group A) after the first 12 weeks of orthodontic treatment. 3...

متن کاملCombined effects of different heat treatments and Cu element on transformation behavior of NiTi orthodontic wires.
The shape memory nickel-titanium alloy has been applied in many fields due to its unique thermal and mechanical performance. One of the successful applications of NiTi wires is in orthodontics because of its good characteristics such as low stiffness, high spring back, high stored energy, biocompatibility, superelasticity and shape memory effect. The mechanical properties of wires are paid spec...
