Abstract
An orthodontic buccal tube appliance for use with the molars has a tube with a mesial, open-ended cylindrical passage and a distal rectangular passage aligned with the cylindrical passage. The tube is thus adapted for use with either round or rectangular wire in accordance with the preference of the orthodontist. A funnel-shaped wall connects the cylindrical passage to the rectangular passage in order to guide an end of rectangular wire toward a position within the rectangular passage.
