6.3 Positioning the transferbow
The patient should be in an upright position. Loosen
the width setting screw (1.7) and completely open the
transferbow. Introduce the earpieces (6.3) into the
external auditory meatus by slowly pushing the side arms
together. To relieve some of the weight, the patient may
support the UTS 3D by holding the side arms with both
hands.
Do not apply too much pressure when
positioning the earpieces.
Next, tighten the width setting screw (1.7) to set the
width.
6.1 Preparing the bite fork
Coat the bite fork with sufficient hard wax (warmed) or
silicone. Press wax or silicone on the maxillary tooth row.
Make sure that clear occlusal support on both sides is
provided.
