Die Fotografie gibt es seit über einem Jahrhundert. Sie kann am besten als "Kunst" für verschiedene Zwecke beschrieben werden. Sie kann ein Hobby, ein Beruf oder eine Wissenschaft sein, zu der sie sich in den letzten Jahren entwickelt hat. Die Einsatzmöglichkeiten der Fotografie sind immens. Sie reichen von Schnappschüssen in der Familie, die uns an vergangene Zeiten erinnern, bis hin zu Luftaufnahmen, die uns helfen, die Bewegungen des Feindes zu erkennen und eine Kampfstrategie zu planen. Anthropologen und Soziologen studieren Fotografien von verschiedenen Personengruppen, um Hinweise...

La photographie existe depuis plus d'un siècle. Elle peut être décrite comme un "art" à des fins diverses. Il peut s'agir d'un loisir, d'une profession ou d'une science, comme cela a été le cas ces dernières années. Les utilisations de la photographie sont immenses. Elles vont des clichés familiaux, qui sont un rappel de nos jours passés, aux photographies aériennes pour connaître les mouvements de la boucle ennemie et planifier la stratégie de combat. Les anthropologues et les sociologues étudient les photographies de divers groupes de personnes pour trouver des indices sur les...

Photography has been in existence for over a century. It can best be described as an 'Art' for various purposes. It can be a hobby, a profession or a science as it has developed into in recent years. The uses of photography are immense. It varies from family snap shots, which are a reminder of our past days, aerial photographs to learn about enemy loop movements and plan battle strategy. Anthropologists and sociologists study photographs of various groups of people for clues to patterns of human behavior. This book deals about dental photography and its clinical applications in Orthodontics.

Orthodontic tooth movement during space closure is achieved through two types of mechanics. The first type, segmental or sectional mechanics involving closing loops either in a full or sectional archwire. The second type, sliding mechanics, involves either moving the brackets along an archwire or sliding the archwire through the tube or brackets.One of the main differentiating factors between the two types of mechanics pertains to friction. Orthodontic space closure should be individually tailored based on the diagnosis and treatment plan. The effectiveness and superiority of one method over...

Arne Bjork is internationally known for his contributions to the understanding of craniofacial growth. His early publication, The Face in Profile, 1947, made him known all over the world.Bjork practiced as a clinician in Sweden for 14 years before moving to Denmark in 1951, where he chaired the Dept of Orthodontics, Royal Dental College, Copenhagen.This book deals with introduction of Bjork and his contribution in the field of Orthodontics.

Stainless steel has many uses in orthodontics for the fabrication of brackets, arch wires, bands, ligatures, among other appliances. Stainless steel is an alloy composed of iron and carbon that contains chromium, nickel, and other elements that impart the property of resisting corrosion. There are many different stainless steel alloys in the market, some of which are useful in orthodontics due to their properties.
