Crowns and bridges today most crowns are made from alloys. sometimes these alloys are coated with a layer of porcelain for natural appearance. the patient is given a temporary crown to wear while the permanent one is being constructed. after a «try-in» appointment any necessary changes are made and the crown is put into place. when a single crown is not sufficient to mask the defects and the patient has enough natural teeth remaining, a fixed partial denture (bridge) can be used. for some dental problems, for example, insufficient remaining teeth affected by periodontal disease, a removable partial denture may be recommended. both fixed and removable partial dentures depend on the existing teeth for their support, and caution must be taken to avoid damage to these supporting teeth. thorough brushing and flossing, eating a balanced diet, and visiting the dentist regularly will help to ensure the health of the remaining teeth. moreover, some precautions are necessary to avoid fracturing the replaced teeth. задайте к тексту 5 вопросов (общий, спец, альтернативный, разделительный и к подлежащему)

A crossword puzzle is a game of words where the player is given a hint and the number of letters. The player then fills in a grid of boxes by finding the right words. Liverpool journalist, Arthur Wynne invented the first crossword puzzle.Arthur WynneArthur Wynne was born on June 22, 1871 in Liverpool, England. He immigrated to the United States at the age of nineteen. He first lived in Pittsburgh, Pennsylvania, and worked for the Pittsburgh Press newspaper. An interesting side-note, was that Wynne also played violin in the Pittsburgh Symphony Orchestra.Later, Arthur Wynne moved to Cedar Grove, New Jersey and started working for a New York City based newspaper called the New York World. He wrote the first crossword puzzle for the New York World, published on Sunday, December 21, 1913. The editor had asked Wynne to invent a new game for the paper's Sunday entertainment section.View a copy of Arthur Wynne's first crossword puzzleWord-Cross to Cross-Word to CrosswordArthur Wynne's first crossword puzzle was initially called word-cross and was diamond-shaped. The name later switched to cross-word, and then as a result of an accidental typo the hyphen was dropped and the name became crossword.Wynne based his crossword puzzle on a similar but much older game played in ancient Pompeii that translated from Latin to English was called Magic Squares. In Magic Squares, the player is given a group of words and has to arrange them on a grid so that the words read the same way across and down. A crossword puzzle is very similar, except instead of being given the words the player is given clues.Arthur Wynne added other innovations to the crossword puzzle. While the first puzzle wasdiamond-shaped, he later invented horizontal and vertical shaped puzzles; and Wynne invented the use of adding blank black squares to a crossword puzzle.The crossword puzzle in a British publication was published in Pearson's Magazine in February 1922. The first New York Times crossword was published on February 1 1930.First Book of Crossword PuzzlesAccording to the Guinness Book of Records, the first collection of crossword puzzles was published in the USA in 1924. Called The Cross Word Puzzle Book it was the first publication by a new partnership formed by Dick Simon and Lincoln Schuster. The book, a compilation of crossword puzzles from the newspaper New York World, was an instant success and helped to establish publishing giant Simon & Schuster, who continue to produce crossword books to this day.
