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...

• 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...

The aim of this trial was to evaluate and compare perceived pain, discomfort, and jaw function impairment between orthodontic treatments combined with skeletal anchorage and treatment using conventional anchorage with headgear or transpalatal bar. A total of 120 adolescent patients in order to start orthodontic treatment were consecutively recruited and randomized into three groups with differe...

The relationship between the anchorage mechanics and root architecture of Pinus peuce was investigated by carrying out winching tests and examining excavated root systems of 20 mature trees. The root system was dominated by 6.1 ± 1.3 lateral roots, more than 70% of the lateral root cross sectional area (CSA) being distributed in the uppermost 10 cm of soil. Anchorage strength was related to the...

Transforming growth factor-beta (TGF-beta) was originally identified, characterized, and named on the basis of its ability to induce anchorage-independent growth (phenotypic transformation). This effect has received little attention in recent years, probably because the induction of anchorage-independent growth by TGF-beta has been observed only in a few cell lines, of which NRK fibroblasts are...

Anchorage-independent growth is a hallmark of tumor cells. We compared gene expression profiles of anchored and nonanchored human mammary carcinoma cells to study this phenomenon. In this study, we show that anchorage had striking effects on cell growth and morphology but altered transcript levels from a limited number of genes. Only about 1% of mRNA transcripts detected in these cells was alte...
