Abstract
A bracket having a closure slot extending through both sides of the bracket body across art archwire slot for a closure member to secure an archwire. The bracket body has an internal shoulder extending across one side of the closure slot. The closure member is a lengthwise-folded flat spring having a free end positioned and biased to engage the shoulder when closed, and including a ramp forming a cam at the distal end thereof. Pushing the closure member lengthwise in the closure slot with sufficient force depresses the free end to disengage it from the internal shoulder to slide the closure member to an open position. Intermediate retention ears are formed on the core of the closure member to engage opposite lateral sides of the closure slot when open. A bendable tab is formed in the bracket body to block the closure member from removal from one end of the closure slot after insertion therein. The bracket body has twin pairs of tie wings to provide dual modes of closure.
