An interocclusal appliance is formed from a single polymer material composition as one unitary piece or from multiple polymer material compositions as a two-piece preform. The two-piece preform includes a base material and an impression material that has a softening point lower than the base material. Teeth are received into the heat-softened impression material, so as to contour the impression material. A portion of the impression material also may contour to a portion of the user's palate. In certain embodiments, substantially no polymeric material contacts the front surfaces of the front teeth, leading to greater comfort and better air flow between front teeth. In still another embodiment, the appliance fits over front teeth only and no polymeric material contacts the maxillary molars.

A resilient cover for a pinch clamp which fully encloses the clamp providing a smooth, snag free surface. The cover pads the clamp and softens the sharp edges of the clamp, providing an increased level of comfort for the patient using the clamp. The cover also provides an increased level of safety by reducing the likelihood of the clamp being inadvertently opened or closed. The cover closely surrounds the clamp, restricting outward movement of portions of the clamp such as the latch and tongue, reducing the chance of their being accidentally released. Internal nubs extend into the cavity holding the clamp and engage the face openings of the clamp. In addition to holding the cover in place, the nubs resist inward movement of the latch and tongue reducing the chance of the clamp being accidentally engaged. The cover is slit along one side so that it can be placed over the clamp with the clamp positioned on a tube. The slit passes through one or more of the nubs. The nubs engage the clamp and help hold the slit closed. This eliminates the need for an external latch or other mechanism to hold the cover on the pinch clamp.
