Next, starting in the posterior with the back teeth, the pro-

provider passes the blunt metal introducer between two teeth,
below the occlusal contact where the teeth touch, first on the
maxillary teeth, then on the mandibular, as illustrated in the
previous figures. The largest-size Minnie Tie should be used

Now, the provider has applied the Minnie Ties in a loose fash-
ion (Figure 15). Next, the ties are tightened from the anterior
to posterior (front teeth to back teeth). To facilitate this, the
operating provider or team needs to do several things. First,

force and is a similar technique to a two-handed mask ven-

ensure both the front and back teeth are seated, and holding
the jaws together while another provider tightens down the
Minnie Ties.

To describe the process of application in more detail, the first
step to see evaluate the fracture to see if it needs what is called
a bridal wire reduction. This is simply a technique where tra-
ditionally a metal wire is passed on each side of the fracture,
usually two teeth on each side, and tightened, which can help
in reducing the fracture (Figure 13). This can be accomplished
with a Minnie Tie as well and is generally recommended as
