Abstract:
1. An isolating structure for oral use, comprising: a body having a vertically-oriented rigid first element having a portion through the first element substantially transparent to electromagnetic signals, a horizontally-oriented rigid second element, and a deformable third element on a bottom surface of the second element; a sheath surrounding the transparent portion and sealed hermetically to the body, extending away from the body and having an opening at an end furthest from the body, the sheath providing a passage from the opening to the transparent portion for a signal probe; wherein the third element is sufficiently deformable that with the second element positioned over a tooth in an oral cavity, bite pressure deforms the third element to conform to shape of the tooth, stabilizing the body relative to the tooth, and the sheath has a length sufficient that, with the body engaging the tooth, the opening for the signal probe is outside the oral cavity.
