摘要:
A self-ligating orthodontic bracket having no movable or flexible parts includes a base having front and rear surfaces. The rear surface is adapted for attachment to the crown of a tooth. A body member is attached to the base and includes an upper half and a lower half, with facing archwire slot surfaces formed on the lower and upper sides thereof, respectively. One or more slot separating tabs are formed on the body member halves and extend vertically toward the other body member half at least partially beyond the archwire slot surface of the body member half to which the slot separating tab is attached. One or more ligating tabs are formed on the body member halves. The body member halves, slot separating tabs and ligating tabs are arranged such that they define an entry opening to a pair of archwire slots, the openings being non-linear in a mesial-distal direction.
