The specialty of orthodontics has continued to evolve since its advent in the early 20th century. Changes in treatment philosophy, mechanics, and appliances have helped shape our understanding of orthodontic tooth movement. In the 1890‘s, Edward H. Angle published his classification of malocclusion based on the occlusal relationships of the first molars. This was a major step toward the develop...

“Sagging” of the palatal cusp upper second molars is a common finding observed during orthodontic treatment which may develop heavy balancing side contacts, have been found to be detrimental harmonious function masticatory system. Various modifications transpalatal arch (TPA) are advocated correct crossbite, but most them will utilize an additional step soldering wire attachment TPA. In this cl...

OBJECTIVE To quantify the three-dimensional moments and forces produced by pretorqued nickel-titanium (NiTi) rectangular archwires fully engaged in 0.018- and 0.022-inch slots of central incisor and molar edgewise and prescription brackets. MATERIALS AND METHODS Ten identical acrylic dental models with retroclined maxillary incisors were fabricated for bonding with various bracket-wire combin...

The aim of this investigation was to test the hypothesis that there is no difference in microleakage between composite-enamel and composite-wire interfaces, when different composites are used. Forty-five freshly extracted human mandibular incisors separated into three groups were used in the study. Multi-stranded 0.0215 inch diameter wire was bonded to enamel using two conventional (Transbond X...

Introduction: When using sliding mechanics for space closure during orthodontic treatment, friction occurs at the bracket-wire interface. The aim of this study was to evaluate the frictional resistance between monocrystalline (ICE) brackets and Stainless Steel, Beta TMA and NiTi wires. Methods: In this experimental study, we used 5 different types of orthodontic wires. Brackets and wires wer...

OBJECTIVE To compare the frictional resistance between self-ligating and conventional brackets tied to different types of wire. MATERIAL AND METHODS Abzil Kirium Capelozza (Pattern I) and Easy Clip (Roth prescription) incisor brackets were used. An elastomeric ligature or a 0.10-in ligating wire was used to ligate the wire to the Abzil bracket. Three types of orthodontic archwire alloys were ...

This case report describes the surgical management of mucosal entrapment a mini-implant-supported molar distalization appliance.A 17-year-old female patient was referred for removal implant-supported pendulum appliance entrapped in palatal mucosa, which is used by Department Orthodontics. The clinical findings suggested that overlying soft tissue non-inflammatory and occurred due to forceful im...
