Locating centric relation with a leaf gauge

A device called a leaf gauge consists of a number of leaves of plastic and can be used to locate the mandible in centric relation.The leaf gauge, when placed between the anterior teeth, aids the patient in retruding the mandible. The biting force tends to move the condyles against their menisci. Since the patient is applying all pressures, the position of the mandible is not likely to exceed physiologic limits.
