New device for accurately recording centric relation.
A new system for recording jaw relations has been described. It is easy to learn to use correctly, is pleasant to the patient while assisting the patient's neuromusculature into the desired retruded closure at the specific vertical dimension preselected by the dentist, and its uses minimal amounts of recording media. Duplicate records can be quickly made for verification, various recording media may be used, improved stability during mounting is obtained, and the method is applicable in most dentulous and partially edentulous situations. Two elements are used, a dental arch-shaped, partially performed, thin, waterproof wafer and a disposable paper leaf gauge. The paper leaf gauge is narrower and more solid than the plastic leaf gauge and thus forms a better anterior leg of the tripod with the two condyles on patient-guided terminal hinge closures. The leaf gauge of preselected thickness is inserted into a slot in the wafer that has been deformed exactly like the occlusal plane by a previous centric occlusion closure. The system is quick, economical, and less complex than most methods presently used. Even so, it accurately reproduced six check-bites on one patient according to comparisons on the Veri-check instrument (Denar Corp., Anaheim, Calif.).
