Charles Henry Land
Charles Henry Land (born August 1, 1847 , † June 1, 1922 in Detroit , Michigan ) was an American dentist and inventor of the jacket crown . He was called Father of Porcelain Dentistry ( English: " Father of Porcelain Dentistry ").
Life
Compatriot's father, John Scott Land , was born in Scotland and emigrated to the USA via Canada with his wife Emily Hayden and family . Disapproved by his father as a teenager, he started out selling newspapers on the streets of New York and then packed meat at Des Moins . At the age of 21, he learned in Chicago the dentistry . He soon started his practice, but it fell victim to the Chicago firestorm in October 1871. He found his way to Detroit penniless and at the age of twenty he again founded a dental practice. Charles Henry Land married Evangeline Lodge (1850–?) In 1875, who graduated from the University of Michigan with a degree in chemistry in 1899 . They had two children: Evangeline Lodge Land (1876–1954), who married Charles August Lindbergh I (1859–1924) and Charles Henry Land II (1879–1954). His grandson was Charles Lindbergh (1902–1974), who on 20./21. May 1927 the first solo crossing of the Atlantic from New York to Paris without a stopover succeeded.

After gold crowns , especially the front teeth , left a lot to be aesthetically pleasing, the jacket crown (coat crown) made of all-ceramic in tooth color, for which he had applied for a patent in 1889, represented a breakthrough. Ceramic was burned onto a folded platinum cap and shaped into the required shape. Before insertion, the platinum had to be removed from the inside of the crown; then it could be cemented in place. However, the breaking strength was not particularly high. His dental colleagues, who specialize in gold crowns, referred to Land as a quack when he developed his porcelain crowns . Even the Michigan Dental Society , the local dental association, excluded him from the association. He then founded a sales company for his development. His dental colleagues led numerous lawsuits against him, which ultimately led him to bankruptcy .
Until the 1960s, the jacket crown was the reconstruction of a tooth that best corresponded aesthetically to the natural tooth. He also filed over 20 patents relating to the manufacture of dentures and general dentistry. These included improvements in filling technology , surgical procedures, dentures, and systems for producing gold and porcelain inlays .
