clusions often requires intrusion and retraction of the anterior segment, which, in turn, usually necessitate mechanical reinforcement of posterior anchorage.1 Intraoral devices such as transpalatal bars or Nance appliances2 can reduce the need to wear Class II elastics, but can cause mesial movement of the lower first molars and protrusion of the incisors. Additional extraoral anchorage in the...

Tetraploid and near-tetraploid chemically transformed derivatives of the pseudodiploid hamster line BHK 21/clone 13 were prepared in four different ways and their ability to be suppressed for anchorage independence by fusion to the anchorage-dependent parental line was tested. In all cases the presence of a single normal genome, thought on genetic grounds to contain a single suppressor gene, wa...

Aim of the study The aim of this paper is to present a clinical case of an Angle class II malocclusion which was treated with premolar extractions and skeletal anchorage in order to establish the facial and dental balance. Material and methods After the clinical and paraclinical evaluations, it was assigned a diagnostic of a class II, division 2 malocclusion according to Angle classification. T...

E-cadherin inactivation underpins the progression of invasive lobular breast carcinoma (ILC). In ILC, p120-catenin (p120) translocates to the cytosol where it controls anchorage independence through the Rho-Rock signaling pathway, a key mechanism driving tumor growth and metastasis. We now demonstrate that anchorage-independent ILC cells show an increase in nuclear p120, which results in relief...

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-...

Successful replacement of hips is the only solution for severe degenerative diseases such as osteoarthritis (Bird, 1995). During cemented fixation of the acetabular cup, anchorage holes are drilled in the acetabulum, then cement is introduced and pressurised to create cement pegs within the anchorage holes. During physiological activities, the bone cement interface of the acetabulum experiences...

The goal of this research was to evaluate and recommend improvement of wall-to-wall connections for prefabricated wall panels. Results of 6 racking tests and 9 bending tests on full-size 2.44 by 2.44 m walls are presented. The specimens were composed of two 1.22 by 2.44 m segments attached with three different types of connection configurations. Static racking tests were performed according to ...

proposed for use as skeletal anchorage in orthodontic treatment.1-5 In 1992, Wehrbein and colleagues, in collaboration with the Straumann Institute, introduced the Orthosystem*—a sandblasted, chemically treated mini-implant that is narrower (3.3mm), but longer (4mm or 6mm), than previous types.6-9 More recently, Giancotti and colleagues showed a step-by-step procedure for insertion of the Strau...
