<p>PROBLEM TO BE SOLVED: To provide a dentition orthodontic bracket capable of sliding an arch wire and preventing a grip from unintentional opening when a strong rotation is applied. SOLUTION: The dentition orthodontic bracket has a difference in level 17 formed on a ceiling plane 16 in a guide part 14 and a sliding rotation support 22 mounted at the lower end of the grip 20. When the sliding rotation support 22, sliding in contact with the ceiling 16, gets over the difference level 17 from the front side to the rear side, the grip 20 can force down the arch wire 28 toward the bottom of an arch wire slot 13.</p> |
