n a line drawing of pertinent features of a cephalometric radiograph made on a piece of transparent paper placed over the radiograph.
tracing, extraoral,
n a tracing of mandibular movements made outside the oral cavity.
tracing, Gothic arch,
tracing, intraoral,
n a tracing of mandibular movements made within the oral cavity. A tracing made by a mechanical device consisting of a weighted or spring-loaded stylus that is attached to one jaw and contacts a coated plate attached to the other jaw. Movement of the mandible causes a tracing to be formed on the horizontally placed coated plate. When the stylus point is in the apex of the tracing, the mandible is said to be in the horizontal position of centric relation. The shape of the tracing depends on the relative location of the marking point and tracing table. The various tracing shapes have been called
Gothic arch, arrow point, and
sea gull tracings. The apex of a properly made tracing indicates the most retruded unstrained relation of the mandible to the maxillae (i.e., the centric relation). The tracings are made by a stylus or needle point by the movement of the mandible. Unless otherwise designated, stylus tracings are made by lateral movements registered on a horizontal plate.
