A mandibular subluxation device (MSD) is provided. The device includes an upper MSD component and a lower MSD component. The upper MSD component includes and upper tooth guide connected to an upper plate having a pair of depending legs. The upper MSD component further includes an upper force receiving plate. The MSD also includes a lower MSD component. The lower MSD component includes a lower tooth guide connected to a lower plate. The lower MSD component further includes a lower force receiving plate. The upper and lower MSD components are connected in a way that allows relative longitudinal movement between the two components between a neutral position and a plurality of extended positions. A ratchet mechanism inhibits movement of the lower plate from any extended position toward the neutral position. The ratchet mechanism may be manually disengaged to allow the lower MSD component to return to the neutral position.
1. A mandibular subluxation device comprising: a first mandibular subluxation component including an upper plate and an upper tooth guide connected to the upper plate;a second mandibular subluxation component including a lower plate and a lower tooth guide connected to the lower plate;the first mand
1. A mandibular subluxation device comprising: a first mandibular subluxation component including an upper plate and an upper tooth guide connected to the upper plate;a second mandibular subluxation component including a lower plate and a lower tooth guide connected to the lower plate;the first mandibular subluxation component connected with the second mandibular subluxation component to allow relative longitudinal movement between the first and second mandibular subluxation components between a neutral position and at least one extended position; anda ratchet mechanism acting between the first and second mandibular subluxation components, the ratchet mechanism allowing for movement of the second mandibular subluxation component from the neutral position to an extended position and inhibiting movement of the second mandibular subluxation component from an extended position toward the neutral position. 2. The mandibular subluxation device as set forth in claim 1 wherein the ratchet mechanism comprises a pawl on one of the upper plate or the lower plate and a plurality of teeth on the other of the upper plate or the lower plate. 3. The mandibular subluxation device as set forth in claim 2 wherein the upper plate further comprises a pair of spaced apart slits, the upper plate including a central portion between the spaced apart slits and outer portions disposed outwardly of the slits. 4. The mandibular subluxation device as set forth in claim 3 wherein the central portion of the upper plate can flex relative to the outer portions, the central portion including the pawl thereon. 5. The mandibular subluxation device as set forth in claim 4 wherein the first mandibular subluxation component further comprises an upper force receiving plate extending transversely to the upper plate having a pair of outermost sections secured to the outer portions of the upper plate and a center section secured to the center portion of the upper plate. 6. The mandibular subluxation device as set forth in claim 4 wherein the plurality of teeth are disposed on the lower plate and wherein the pawl is adapted to engage at least one tooth. 7. The mandibular subluxation device as set forth in claim 6 wherein the second mandibular subluxation component further comprises an lower force receiving plate extending transversely to the lower plate. 8. The mandibular subluxation device as set forth in claim 6 wherein the pawl includes a ramped surface and a generally vertical surface and each tooth includes a ramped surface and a generally vertical surface, the ramped surfaces of the pawl and tooth allow the pawl to move over the tooth as the second mandibular subluxation component is being moved to an extended position and the generally vertical surfaces of the pawl and tooth cooperating to inhibit movement of the second mandibular subluxation component from being moved from an extended position toward the neutral position. 9. The mandibular subluxation device as set forth in claim 8 wherein the first mandibular subluxation component includes a pair of legs depending from the outer portions of the upper plate, each of the legs including a lip thereon, the upper plate, legs and lips cooperating to form a guide to receive the lower plate of the second mandibular subluxation component. 10. The mandibular subluxation device as set forth in claim 8 wherein the central portion of the upper plate is adapted to receive a force to move the center section so as to disengage the pawl from the tooth to allow the second mandibular subluxation component to move toward the neutral position. 11. The mandibular subluxation device as set forth in claim 10 wherein the second mandibular subluxation component includes at least one stop for limiting relative longitudinal movement between the first mandibular subluxation component and the second mandibular subluxation component. 12. A method of mandibular subluxation comprising: positioning an upper tooth guide of a first mandibular subluxation component relative to a patient and positioning a lower tooth guide of a second mandibular subluxation component relative to a patient, the second mandibular subluxation component being in a neutral position;applying a force to the second mandibular subluxation component in a direction away from the patient to move the second mandibular subluxation component relative to the first mandibular subluxation component from the neutral position to an extended position to thereby distract the patient mandible; andmaintaining the second mandibular subluxation component in an extended position by a ratchet mechanism on the first mandibular subluxation component and the second mandibular subluxation component. 13. The method of mandibular subluxation as set forth in claim 12 further comprising releasing the ratchet mechanism to thereby allow the second mandibular subluxation component to be moved toward the neutral position.
