Accidental ingestion or inhalation of foreign bodies has been widely documented, including incidents which occur whilst undertaking dental treatment. Most ingested objects pass through the gastrointestinal tract (GIT) spontaneously, but approximately 10%-20% need to be removed endoscopically and 1% require surgery. This case reports a complication arising from the accidental loss of an archwire...

introduction: the aim of this study was to assess the galvanic behavior of different bracket and archwire combinations that are commonly used in orthodontic treatments. methods: three types of orthodontic archwires with a diameter of 0.016×0.022 inch and 80 standard edgewise maxillary central incisor brackets were selected. three groups consisted of different wire-bracket couples and one group ...

BACKGROUND The aim of this study is to calculate and compare the play and torque expression of 0.018 and 0.022 bracket slots when engaged with archwires of different size, cross section and material. METHODS Eight orthodontic brackets, two of slot height 0.018 and six of slot height 0.022, from different manufacturers, were measured and fixed to a vertical support. Twenty-four archwires of di...

OBJECTIVE The purpose of this study was to observe stress distribution and displacement patterns of the entire maxillary arch with regard to distalizing force vectors applied from interdental miniscrews. METHODS A standard three-dimensional finite element model was constructed to simulate the maxillary teeth, periodontal ligament, and alveolar process. The displacement of each tooth was calcu...

The aim of this study was to assess the effect of the moments generated with low- and high-torque brackets. Four different bracket prescription-slot combinations of the same bracket type (Mini Diamond® Twin) were evaluated: high-torque 0.018 and 0.022 inch and low-torque 0.018 and 0.022 inch. These brackets were bonded on identical maxillary acrylic resin models with levelled and aligned teeth ...

Background: Bodily alignment of teeth that are blocked out of the arch such as a lingually placed lateral incisor, is often time consuming and difficult. Though several treatment methods are available for accomplishing this, these approaches have some drawbacks. Aim: To describe how Mollenhauer aligning auxiliary (MAA) can be adapted to bodily align lingually blocked-out lateral incisors in pre...

Newton’s third law of motion states that whenever a force is applied an equal and opposite force occurs in the opposite direction of applied force. Orthodontic tooth movement (OTM) being a biological phenomenon; sound knowledge of biomechanics is required. Sliding mechanics is a common approach in orthodontics to achieve tooth movement for closure and gaining of space.1,2 Sliding mechanics invo...

INTRODUCTION The purpose of this study was to compare the frictional force (FF) generated by various combinations of self-ligating bracket (SLB) types, archwire sizes, and alloy types, and the amount of displacement during the initial leveling phase of orthodontic treatment, by using a custom-designed typodont system. METHODS Two passive SLBs (Damon 2 [D2] and Damon 3 [D3]), and 3 active SLBs...

INTRODUCTION The aim of this study was to evaluate the frictional resistance between active and passive self-ligating brackets and 0.019 × 0.025-in stainless steel archwire during sliding mechanics by using an orthodontic sliding simulation device. METHODS Maxillary right first premolar active self-ligating brackets In-Ovation R, In-Ovation C (both, GAC International, Bohemia, NY), and SPEED ...
