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...

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...

a 16-year-old class ii female patient was treated without tooth extraction. the upper first molars were distalized by the pendulum appliance. after six months, the molars tipped significantly to the distal. to correct this side effect, we decided to upright the molars using skeletal anchorage. on each side, a mini-screw was inserted between first and second premolars in the buccal cortical plat...

Developments in digitisation and the need to reduce carbon emissions have increased attention on port call optimisation. Just-in-time arrival for ships is recognised literature as being achieved more readily container trades than bulk trades. This paper examines governance trade logistics conditions of Vancouver, Canada, increasing number at anchor gives rise explore absence initiatives limit a...
