W-beam systems utilize end-terminal anchorages to develop tension upstream and downstream of an impact event. However, the capacities of the anchorage components under impact loading are not well known. One such W-beam end anchorage system, the Midwest guardrail system (MGS) trailing-end anchorage, was evaluated using three dynamic component tests _ a soil foundation tube pull test, a breakaway...

INTRODUCTION The goal of this retrospective cephalometric study was to compare orthodontic outcomes in patients with maxillary dentoalveolar protrusion malocclusion treated with extraoral headgear or mini-implants for maximum anchorage. MATERIALS Forty-seven subjects with Angle Class II malocclusion or Class I bimaxillary dentoalveolar protrusion were treated by retracting the maxillary dento...

The aim of this study was to review the literature and evaluate failure rates factors that affect stability success temporary anchorage devices (TADs) used as orthodontic anchorage. Data collected from electronic databases: MEDLINE database Google Scholar. Four combinations term were keywords: “micro-implant”, “mini-implant”, “mini-screw”, “orthodontics”. following selection criteria select app...

One of the most important phases of oral health is the form and function of the oral mechanism. Recently, pediatric dentists are concerned with the obvious esthetic disabilities and the pathologic implications of the malposed teeth. Interceptive and functional orthodontic treatment is playing a major role in these discrepancies. Anchorage is an important consideration in orthodontics, particula...

this paper presented a multimodal discourse analysis of some visual images in the political rally discourse of 2011 electioneering campaigns in southwestern nigeria. the data comprised purposively selected political visual artefacts from political rallies across the six southwestern states in nigeria (osun, oyo, ondo, ekiti, ogun, and lagos). the data were analyzed using halliday’s (1985) syste...

BACKGROUND The term anchorage in orthodontic treatment refers to methods of controlling unwanted tooth movement. This is provided either by anchor sites within the mouth, such as the teeth and the palate, or from outside the mouth (headgear). Recently, new methods of providing anchorage have been developed using orthodontic implants which are surgically inserted into the bone in the mouth. This...

The bearing plate is an important part of a tendon–anchorage subsystem; however, its function and safety can be compromised by factors such as fatigue corrosion. This paper explores the feasibility electromechanical impedance (EMI) technique for crack detection in prestressed anchorage. Firstly, theory EMI presented. Next, well-established anchorage literature selected target structure. Thirdly...
