Release system for treatment of a broken jaw

An apparatus for use in holding together the upper and lower dental arches of a patient, comprising:

• a first arch bar formed of an elongated flat band of malleable material capable of being conformed to the curvature of the dental arches of the patient, the band presenting opposing front and back surfaces and upper and lower edges and defining a longitudinal axis;
• a plurality of closed loops supported on the first arch bar and protruding from the front surface of the flat band, each loop presenting an opening extending in a direction parallel to the longitudinal axis of the first arch bar, and the loops being spaced from one another along the longitudinal axis to define a channel;
• a second arch bar formed of a malleable material capable of being conformed to the curvature of the dental arches of the patient;
• a fastening means for fastening the first and second arch bars to the dental arches of the patient;
• an elongated release bar formed of a malleable material capable of being conformed to the curvature of the longitudinal axis of the first arch bar and presenting proximal and distal ends, the release bar being sized for receipt in the channel defined by the loops and including a means at the proximal end for permitting gripping and handling of the release bar;
• and
• a tying means for tying the release bar and the second arch bar together when the release bar is received in the channel to immobilize the arch bars relative to one another, the release bar being removable from the channel to release the tying means so that the first and second arch bars are movable relative to one another, wherein each loop includes a depending portion supported on the upper edge of the flat band and an upturned portion that is turned inward toward the front surface of the band and upward to form the loop, the upturned portion defining a spacing means for spacing the release bar from the flat band when the release bar is received in the channel, facilitating tying of the tying means.

• a housing for the distal end of said release bar, said housing including a sleeve for insertion through at least one of said loops, means for engaging said sleeve to said first arch bar and an aperture for insertion of said distal end of said release bar into said sleeve;
• and
• a tying means for tying the release bar and the second arch bar together when the release bar is received in the channel to immobilize the arch bars relative to one another, the release bar being removable from the channel to release the tying means so that the first and second arch bars are movable relative to one another.

An orthodontic surgery apparatus for use in holding together the upper and lower dental arches of a patient comprising:

• a first arch bar for the upper dental arch;
• channel means on said arch bar for presenting a channel projecting from said first arch bar for insertion of a release bar therethrough;
• an elongated tab attached to said channel means, the tab being folded about said first arch bar to connect said channel means to said first arch bar;
• a second arch bar for the lower dental arch;
• a release bar having proximal and distal ends for extension through said channel means of said first arch bar;
• and
• means extending between said release bar and said second arch bar in a manner for urging said first arch bar and said second arch bar, and said dental arches together;
• said proximal end of said release bar being manipulated by a user to withdraw said release bar from said channel means and said urging means, whereby to allow said first and second arch bars and dental arches to move in a direction apart from each other.
