摘要:
The dental appliance-holding bracket assembly includes a plurality of housings attached to a corresponding tooth band, each of the tooth bands being cemented to the crown of an adjoining tooth. Each housing defines a socket of a ball-and-socket joint. The assembly further includes a plurality of bracket arms, each bracket arm having a shank including a proximal end and an opposing distal end. The proximal end of the shank has a ball pivotally captured within the housing socket to form a ball-and-socket joint, while the opposing distal end of the shank includes a ring adapted for supporting a dental appliance.
