        OJW rationale and wiring instructions

                                                                                                                                                                                   

 

Wiring begins at oval diagram A at top center and continues on clockwise thru B, C, D, E and F

 

Ligature wire cutter... Deadsoft wire.... 5" Mathieu needle holder

Note the position of the vertical posts: (toward the back on the upper (distal) and toward the front on the lower (mesial)
*If you think of the brackets as #1,2,3,4,5,6 from upper left to  lower right then...

...with the top half of the wire remaining passive, the bottom half begins the wrapping as follows: #1,2,3, 6: The wire first engages #1, the bracket on upper right second premolar;  and
   

Then finish wrapping the upper half of the wire in this sequence: #1, 4, 5, 6. When the lower wire passes over and around #5 it is passed over #6 and wrapped into a pigtail" by joining the  upper and lower strand  together in front

... both strands are twisted together 5-7 times until patient can move 2.0 mm-2.5 mm in all directions...

.     ...and then tucked in.

Note the vertical posts on these brackets: they allow the patient to rewire themselves easily and apart the requisite distance... "THE OJW POSITION OF PHYSIOLOGIC REST" 

THE OJW POSITION OF PHYSIOLOGIC REST is a parted resting position of the mandible at which the muscles of mastication are in a minimally contracted position thereby allowing the lower jaw to be suspended from the maxillary teeth in a condition of "weightlessness". Inter-occlusal wiring permits the mandible to move  2.0 mm - 4.0 mm laterally, vertically and antero-posteriorly  thereby minimally impeding speech and minimizing the possibility of TMJ stiffening. This position is often congruent with an observable inter-occlusal space of 2.0 mm - 4.0 mm and closely approximates the position we know as the "physiologic jaw resting" position, the initial position  from which all jaw excursions begin. It is this condition of  jaw "weightlessness" that precludes the possibility that the upper/lower teeth are extruded during the time the OJW device is in place.

Model demonstrates how OJW can be accomplished using the "parallelogram" wiring method. The wire is seen passing thru the slot of the bracket. However the wire in most other kinds of bracket would be passed around the vertical posts NOT EMBEDDED IN THE  BRACKET SLOT.
