The clinical routine has been undergoing continuous changes since it was defined by Angle[1]. Looking into the literature most changes occur following the presentation of a new approach. This was the case with the introduction of the skeletal anchorage by Creekmore [2] and Eklund. A hypothesis can be created based on single observations and research can be started. The present paper is a “story...

The load transfer mechanisms of cable bolts differ from those for normal rebar bolts. The cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. Tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. The tendon strength can be evaluated by the tensi...

For many years, orthodontists have searched for a form of anchorage that does not rely on patient cooperation, although the answer already lay in the implants dentists used to replace missing teeth and oral surgeons used to hold bone segments together. Now these divergent lines have come together in the form of stationary anchorage, and titanium is the most biocompatible material. State-of-the-...

Aims and Objectives The aim of this article is to re-evaluate anchorage coefficient values in orthodontics and their influence in the treatment decision through the usage of three-dimensional (3D) scanner. Materials and Methods A sample of 80 patients was analyzed with the 3D scanner using the C2000 and Cepha 3DT softwares (CIRAD Montpellier, France). Tooth anatomy parameters (linear measurem...

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...

Metastatic breast cancer remains the chief cause of cancer-related death among women in the Western world. Although loss of cell–cell adhesion is key to breast cancer progression, little is known about the underlying mechanisms that drive tumor invasion and metastasis. Here, we show that somatic loss of p120catenin (p120) in a conditional mouse model of noninvasive mammary carcinoma results in ...

The aims of this study were to compare dental and skeletal treatment changes in Class II division 1 malocclusions with two modes of maxillary control and two modes of bite-jumping. The subjects comprised Chinese children with severe Class II division 1 malocclusions, i.e. 21 consecutive subjects (13.4 +/- 1.4 years) treated with a headgear Herbst appliance and step-by-step advancement (HHSSA) o...
