Molar appliance for orthodontic therapy |
摘要 |
An orthodontic appliance for a molar tooth has a latch that is movable between an open position to admit or release an archwire into an archwire slot and a closed position to retain the archwire in the archwire slot. In one aspect of the invention, the appliance lacks tiewings and has a mesial archwire guide that is spaced from a distal archwire guide by a channel that extends in a generally occlusal-gingival direction across the appliance. In another aspect of the invention, the appliance includes a flange with at least one groove for retaining a wire segment or other item in place.
