Japanese nickel titanium (NiTi) alloy wire possesses excellent spring-back properties, shape memory and super-elasticity. In order to adapt this wire to clinical use, it is necessary to bend as well as to control its super-elastic force, and so a direct electric resistance heat treatment (DERHT) method was developed. An electric current is passed directly through the wire, thus generating enoug...

Aims and Objective Denture fractures are a common problem in clinical practice. Despite the use of different reinforcement materials (metal wires, metal plates, and various types of fibers) for denture repairs, recurrent fractures are still common. The purpose of this study was to compare the maximum flexural loads of the heat-polymerized denture base resin when repaired with autopolymerizing r...

Additive manufacturing (AM) using wire as an input material is currently in full swing, with very strong growth prospects thanks to the possibility of creating large parts, high deposition rates, but also a low investment cost compared powder bed fusion machines. A versatile 3D printing device Direct Energy Deposition Wire-Laser (DED-W Laser) Precitec Coaxprinter station melt metallic filler de...

BACKGROUND Torque of the maxillary incisors is crucial to occlusal relationship and esthetics and can be influenced by many factors. The aim of this study was to assess the relative influence of the material of the orthodontic appliance (adhesive, bracket, ligature, and wire) on tooth displacements and developed stresses/strains after torque application. METHODS A three-dimensional upper righ...

The aim of this study was to analyse the peel resistance of silver plated wires examined in an intraoral setting. In this study, a 0.016 × 0.016 inch silver plated stainless steel wire and a 0.016 × 0.016 inch Teflon-coated nickel-titanium wire were investigated. The brackets of ceramic and stainless steel were bonded to the first and second bicuspids of two subjects. We investigated peel resis...

The aim of this study was to evaluate deflection forces of orthodontic wires of different alloys engaged into conventional brackets using several ligation types. Stainless steel, conventional superelastic nickel-titanium and thermally activated nickel-titanium archwires tied into conventional brackets by a ring-shaped elastomeric ligature (RSEL), a 8-shaped elastomeric ligature (8SEL) and a met...

In this paper, a simple and versatile route was introduced to prepare solid-phase microextraction coatings on the chemically inert titanium wire. Titania nanotube array film can be created on metallic substrates by electrochemical anodization in fluoride-containing electrolytes and subsequently support various secondary reactions to prepare functional surfaces. In the present work, titania nano...
