A right bite pad assembly is slidingly connected to and completely encloses the right aft end portion of the buccal strap. A left bite pad assembly is slidingly connected to and completely encloses the left aft end portion of the buccal strap. The right bite pad assembly can include a right upper bite surface member for contacting right upper molars of a wearer and a right lower bite surface member for contacting right lower molars of the wearer. The left bite pad assembly can include a left upper bite surface member for contacting left upper molars of a wearer and a left lower bite surface member for contacting left lower molars of the wearer. A right channel extends through the right upper bite surface member and the right lower bite surface member. A left channel extends through the left upper bite surface member and the left lower bite surface member.

Abstract: An orthodontic bracket system including a plurality of interchangeable ligation covers so as to allow the patient and practitioner to create a desired aesthetic look. The inventive orthodontic bracket system includes a bracket base, at least one arch wire slot formed in the bracket base adapted to receive an arch wire therein, a first interchangeable ligation cover that when releasably assembled to the bracket base can be selectively moved relative to the bracket base between an open non-ligating position relative to the arch wire slot and a closed, ligating position relative to the arch wire slot, and a second interchangeable ligation cover of a different color and/or formed of a different material relative to the first cover. The interchangeable ligation covers can be removed and replaced with another cover of a different color and/or different material to create a different aesthetic appearance.
