Triple Tray Impressions
Stalagmite® (using the Articulated Triple Tray System)
Adding acrylic stop rods:
Stop-rods are shown on Bases without models for illustration purposes
There are notches at the anterior and posterior ends of all the RTP Bases. These notches are for round plastic-stop-rods to maintain the vertical relationship between the Upper and Lower Bases. A thin (.030" or .75mm) membrane needs to be removed with a small fissure bur to allow the rod (3/16" or 4.75mm) to pass through. Once in place, add a drop of super-glue to secure it to the base.
A combination of designs can be used. Rods of one length or two rods meeting near the occlusal plane are examples shown above.
If the square hinge-stop-rods are to be used to
maintain the vertical dimension at the posterior end, the upper stop-rod must
be in contact with the lower stop-rod to be effective.
there will be a slight gap between the two stop-rods or they will make contact prematurely.
The gap can be built up with glue or acrylic and ground in. If contact
is premature it can be ground in with a thin strip of articulating tape
until the teeth are in occlusal contact.
