MAGNETS AN ATTRACTIVE WEAPON IN THE WAR ON CROOKED TEETH

 TORONTO, May 17 /PRNewswire/ -- Magnets can be an attractive solution to some orthodontic problems in children. At the same time, they can repel problems parents sometimes may have in getting their children to wear orthodontic appliances.
 Dr. T.M. Graber, of Evanston, Ill., today discusses his latest findings in the use of magnets in orthodontics, Monday, May 17, during the 1993 Annual Sessions of the American Association of Orthodontists in Toronto. The meeting, which runs through Wednesday, has attracted more than 10,000 participants.
 Tiny magnets, three to four millimeters in diameter, are made of materials such as samarium-cobalt and neodymium-iron-boron. These are essentially the same type of magnets used in stereo equipment and other electronics.
 Depending on the type of orthodontic problem being treated, magnets are used to pull teeth in a certain direction or to push them apart. According to Graber, "One advantage of magnets is that they provide a continuous, durable force."
 Graber recently has begun to use surgically implanted magnets to pull down eye teeth impacted in the roof of children's mouths. Using conventional orthodontic methods, this procedure can take up to two years. Magnets, however, can be used to accomplish the same goal in one-third the time, Graber said.
 Magnets also can be used to open or close spaces between teeth, expand the roof of the mouth and correct open bites, conditions in which some teeth can't be brought into contact with opposing teeth.
