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...

Establishment of proper anchorage must be one of the most important keys to achieve successful results in treating Class II patients. In this decade, emergence of temporary anchorage devices (TADs) has completely changed the treatment strategy, providing sufficient anchorage without patient compliance. 1, 2 In this lecture, I would like to introduce effective usage of TADs in Class II treatment...

Bi-maxillary protrusion is a condition with protrusive and proclined upper lower incisors the patient not able to close lips without strain. The presented case reported chief complaint of forwardly placed teeth, skeletal class II malocclusion, Angle’s I malocclusion incisors. treatment was performed extraction all first premolars retraction under absolute anchorage. about 3 mm 3.5 achieved resp...

M olar distalization for the treatment of Class II malocclusions has historically depended on patient compliance with intra-and extraoral auxiliaries. 1-5 In recent years, " non-compliance " devices such as the Distal Jet,* 6,7 Jones Jig,* 8 Pendulum,** 9 and repelling magnets 10 have been developed. The problem of anchorage loss during molar distaliza-tion with these appliances has not been so...

The intensive increase of global warming every year affects our world negatively and severely. use renewable energy sources has gained importance in reducing eliminating the effect warming. To this end, new technologies are being developed to facilitate these resources. One technological developments is floating wind turbine. In order evaluate respective environmental footprint systems, a life ...

• Self-anchored prestressed CFRP plates without the need for mechanical end anchorage. Significant improvement in bending stiffness, crack width, and load-carrying capacity. Nonlinear finite element analyses of flexural cracks crack-induced debonding plates. This paper presents an innovative method prestressing carbon fibre reinforced polymer (CFRP) used as externally bonded reinforcement stren...

-Analysis and design provisions for the bond and anchorage length of deformed reinforcing bars in reinforced concrete elements are typically developed based on the assumption that the strain variations along the bar becomes approximately linear at or near the ultimate state of bond failure. Hence the assumption of the development of uniform bond stress along the anchorage length is used to calc...

We examined the tonal alignment and scaling patterns of the start and end points of the French late rise, using a rate manipulation paradigm. Our findings call into question aspects of the segmental anchoring hypothesis: the low starting point of the late rise was not stably anchored to a segmental landmark, and for some speakers, F 0 excursion size varied across rates. The position of the peak...
