dc.description.abstractOrthodontic archwires play a crucial role in orthodontic treatment, serving as a primary component in fixed appliances by delivering controlled forces for tooth movement. This thesis explores the materials, mechanical properties, and recent advancements in archwire technology to optimize clinical outcomes. The study begins by reviewing the evolution of orthodontic archwires, from early gold and stainless steel wires to modern alloys such as nickel-titanium (NiTi), beta-titanium, and cobalt-chromium. Each material’s mechanical properties, including elasticity, strength, biocompatibility, and friction characteristics, are analyzed in detail. Special attention is given to the influence of wire shape, cross-section, and stiffness on tooth movement efficiency and patient comfort. Recent advancements in coating technologies have further improved archwire performance. Coatings such as physical vapor deposition (PVD), chemical vapor deposition (CVD), and functional surface treatments enhance corrosion resistance, friction reduction, and biocompatibility. Additionally, antimicrobial coatings with silver nanoparticles have shown promise in reducing bacterial colonization, addressing common oral hygiene concerns associated with orthodontic appliances. Aesthetic considerations have also driven the development of tooth-colored archwires using epoxy, teflon, and rhodium coatings. These materials maintain mechanical performance while improving patient satisfaction. The thesis evaluates the durability of these coatings and their impact on force transmission, wear resistance, and plaque accumulation. Furthermore, the study examines the clinical applications of specialized archwires such as superelastic NiTi, copper NiTi, bioforce wires, and fiber-reinforced composite wires, highlighting their role in different treatment phases. Comparative analyses of friction, load-deflection characteristics, and long-term stability guide material selection for optimal treatment efficiency. In conclusion, ongoing innovations in orthodontic archwire materials and coatings have significantly enhanced treatment effectiveness, aesthetics, and patient comfort. Future research should focus on developing advanced biocompatible materials and surface modifications to further optimize orthodontic outcomes while minimizing treatment duration and adverse effects.
