Effects of Topical Fluoride Prophylactic Agents on the Mechanical Properties of Orthodontic Nickel-titanium Closed Coil Springs and Stainless Steel Closed Coil Springs
The purpose of this study was to investigate the effects of topical fluoride prophylactic agents on the mechanical unloading properties of nickel-titanium (NiTi) and stainless steel (SS) closed coil springs. Spring were stored at 37 ̊C under static load in phosphate buffered saline (PBS) and treated with either neutral sodium fluoride (NaF) or acidulated phosphate fluoride (APF) five days per we...
متن کاملMechanical Analysis of Orthodontic Wires
Orthodontic tooth movement is a physiologic response to externally applied forces; the motive forces are primarily mechanical. The optimal application of orthodontic force enables maximum movement of teeth with minimal irreversible damage of the periodontal ligament (PDL), alveolar bone, and teeth. Since arch wires are the main force system in orthodontics, it is important in clinical practice ...
متن کاملMechanical behavior and clinical application of nickel-titanium closed-coil springs under different stress levels and mechanical loading cycles.
INTRODUCTION The main advantage of superelastic nickel-titanium (NiTi) products is their unique characteristic of force plateaus, which allow for clinically precise control of the force. The aims of this study were to define the mechanical characteristics of several currently available closed-coil retraction springs and to compare these products. METHODS A universal test frame was used to acq...
