Prognathism
Prognathism, also called Habsburg jaw or Habsburgs' jaw primarily in the context of its prevalence amongst members of the House of Habsburg, is a positional relationship of the mandible or maxilla to the skeletal base where either of the jaws protrudes beyond a predetermined imaginary line in the coronal plane of the skull. In general dentistry, oral and maxillofacial surgery, and orthodontics, this is assessed clinically or radiographically ( cephalometrics). The word ''prognathism'' derives from Greek πρό (''pro'', meaning 'forward') and γνάθος (''gnáthos'', 'jaw'). One or more types of prognathism can result in the common condition of malocclusion, in which an individual's top teeth and lower teeth do not align properly. Presentation Prognathism in humans can occur due to normal variation among phenotypes. In human populations where prognathism is not the norm, it may be a malformation, the result of injury, a disease state or a hereditary condition. Prognathism ...

House Of Habsburg
The House of Habsburg (), alternatively spelled Hapsburg in Englishgerman: Haus Habsburg, ; es, Casa de Habsburgo; hu, Habsburg család, it, Casa di Asburgo, nl, Huis van Habsburg, pl, dom Habsburgów, pt, Casa de Habsburgo, la, Domus Habsburg, french: Maison des Habsbourg and also known as the House of Austriagerman: link=no, Haus Österreich, ; es, link=no, Casa de Austria; nl, Huis van Oostenrijk, pl, dom Austrii, la, Domus Austriæ, french: Maison d'Autriche; hu, Ausztria Háza; it, Casa d'Austria; pt, Casa da Áustria is one of the most prominent and important dynasties in European history. The house takes its name from Habsburg Castle, a fortress built in the 1020s in present-day Switzerland by Radbot of Klettgau, who named his fortress Habsburg. His grandson Otto II, Count of Habsburg, Otto II was the first to take the fortress name as his own, adding "Count of Habsburg" to his title. In 1273, Count Radbot's seventh-generation descendant Rudolph I of German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retrognathia
Retrognathia is a type of malocclusion which refers to an abnormal posterior positioning of the maxilla or mandible, particularly the mandible, relative to the facial skeleton and soft tissues. A retrognathic mandible is commonly referred to as an overbite, though this terminology is not used medically.

Inbreeding
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious or recessive traits resulting from incestuous sexual relationships and consanguinity. Animals avoid incest only rarely. Inbreeding results in homozygosity, which can increase the chances of offspring being affected by recessive traits. In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce. An individual who inherits such deleterious traits is colloquially referred to as ''inbred''. The avoidance of expression of such deleterious recessive alleles caused by inbreeding, via inbreeding avoidance mechanisms, is the main selective reason for ou ...

Charles II Of Spain
Charles II of Spain (''Spanish: Carlos II,'' 6 November 1661 – 1 November 1700), known as the Bewitched (''Spanish: El Hechizado''), was the last Habsburg ruler of the Spanish Empire. Best remembered for his physical disabilities and the War of the Spanish Succession that followed his death, Charles's reign has traditionally been viewed as one of managed decline. However, many of the issues Spain faced in this period were inherited from his predecessors and some recent historians have suggested a more balanced perspective. For reasons that are still debated, Charles experienced extended periods of ill health throughout his life and from the moment he became king at the age of three in 1665, the succession was a prominent consideration in European politics. Historian John Langdon-Davies summarised his life as follows: "Of no man is it more true to say that in his beginning was his end; from the day of his birth, they were waiting for his death". Despite this, his successors in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thumb Sucking
Thumb sucking is a behavior found in humans, chimpanzees, captive ring-tailed lemurs, and other primates.Benjamin, Lorna S.: "The Beginning of Thumbsucking." ''Child Development'', Vol. 38, No. 4 (Dec., 1967), pp. 1065–1078. It usually involves placing the thumb into the mouth and rhythmically repeating sucking contact for a prolonged duration. It can also be accomplished with any organ within reach (such as other fingers and toes) and is considered to be soothing and therapeutic for the person. As a child develops the habit, it will usually develop a "favorite" finger to suck on. At birth, a baby will reflexively suck any object placed in its mouth; this is the sucking reflex responsible for breastfeeding. From the very first time they engage in nutritive feeding, infants learn that the habit can not only provide valuable nourishment, but also a great deal of pleasure, comfort, and warmth. Whether from a mother, bottle, or pacifier, this behavior, over time, begins to become ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthodontics
Orthodontics is a dentistry specialty that addresses the diagnosis, prevention, management, and correction of mal-positioned teeth and jaws, and misaligned bite patterns. It may also address the modification of facial growth, known as dentofacial orthopedics. Abnormal alignment of the teeth and jaws is very common. Nearly 50% of the developed world's population, according to the American Association of Orthodontics, has malocclusions severe enough to benefit from orthodontic treatment: although this figure decreases to less than 10% according to the same AAO statement when referring to medically necessary orthodontics. However, conclusive scientific evidence for the health benefits of orthodontic treatment is lacking, although patients with completed orthodontic treatment have reported a higher quality of life than that of untreated patients undergoing orthodontic treatment. Treatment may require several months to a few years, and entails using dental braces and other appliances ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emperor Kōmei
was the 121st Emperor of Japan, according to the traditional order of succession.Imperial Household Agency (''Kunaichō'')孝明天皇 (121)/ref> Kōmei's reign spanned the years from 1846 through 1867, corresponding to the final years of the Edo period.Meyer, Eva-Maria. (1999) ''Japans Kaiserhof in der Edo-Zeit'', p. 186./ref> During his reign there was much internal turmoil as a result of Japan's first major contact with the United States, which occurred under Commodore Perry in 1853 and 1854, and the subsequent forced re-opening of Japan to western nations, ending a 220-year period of national seclusion. Emperor Kōmei did not care much for anything foreign, and he opposed opening Japan to Western powers. His reign would continue to be dominated by insurrection and partisan conflicts eventually culminating in the collapse of the Tokugawa shogunate shortly after his death and the Meiji Restoration in the beginning of the reign of his son and successor Emperor Meiji.

Cornelia De Lange Syndrome
Cornelia de Lange syndrome (CdLS) is a genetic disorder. People with this syndrome experience a range of physical, cognitive, and medical challenges ranging from mild to severe. The syndrome has a widely varied phenotype, meaning people with the syndrome have varied features and challenges. The typical features of CdLS include thick or long eyebrows, a small nose, small stature, developmental delay, long or smooth philtrum, thin upper lip and downturned mouth. The syndrome is named after Dutch pediatrician Cornelia Catharina de Lange, who described it in 1933. It is often termed Brachmann de Lange syndrome or Bushy syndrome and is also known as Amsterdam dwarfism. Its exact incidence is unknown, but it is estimated at 1 in 10,000 to 30,000. Signs and symptoms The phenotype of CdLS is highly varied and is described as a spectrum; from Classic CdLS (with a greater number of key features) to mild variations with only a few features. Some people will have a small number of features ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mandible
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints. The bone is formed in the fetus from a fusion of the left and right mandibular prominences, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 59 The word "mandible" derives from the Latin word ''mandibula'', "jawbone" (literally "one used for chewing"), from '' mandere'' "to chew" and ''-bula'' ...

Vlad III
Vlad III, commonly known as Vlad the Impaler ( ro, Vlad Țepeș ) or Vlad Dracula (; ro, Vlad Drăculea ; 1428/311476/77), was Voivode of Wallachia three times between 1448 and his death in 1476/77. He is often considered one of the most important rulers in Wallachian history and a national hero of Romania. He was the second son of Vlad Dracul, who became the ruler of Wallachia in 1436. Vlad and his younger brother, Radu, were held as hostages in the Ottoman Empire in 1442 to secure their father's loyalty. Vlad's eldest brother Mircea and their father were murdered after John Hunyadi, regent-governor of Hungary, invaded Wallachia in 1447. Hunyadi installed Vlad's second cousin, VladislavII, as the new voivode. Hunyadi launched a military campaign against the Ottomans in the autumn of 1448, and Vladislav accompanied him. Vlad broke into Wallachia with Ottoman support in October, but Vladislav returned and Vlad sought refuge in the Ottoman Empire before the end of the year. ...

Frederick, Hereditary Prince Of Denmark
Frederick, Hereditary Prince of Denmark ( da, Frederik; 11 October 1753 – 7 December 1805) was heir presumptive to the thrones of Denmark and Norway. He was the only surviving son of King Frederick V by his second wife, Juliana Maria of Braunschweig-Wolfenbüttel. Hereditary Prince Frederick acted as regent on behalf of his half-brother King Christian VII from 1772 to 1784. Life Early life Frederick was born at Christiansborg Palace in Copenhagen on 11 October 1753. To provide for his future position, at the age of 3 he was elected coadjutor in the Prince-Bishopric of Lübeck. This meant that in time he would succeed the Prince-Bishop then in office, Frederick August. This plan had to be abandoned, however, and Frederick stayed in Denmark as a junior member of the royal family. Marriage He married Duchess Sophia Frederica of Mecklenburg-Schwerin (1758–1794) in Copenhagen on 21 October 1774. She was a daughter of Duke Louis of Mecklenburg-Schwerin and Princess Charlott ...
