title: A comparison of lateral interocclusal records to pantographic tracings.
abstract: Many techniques exist to record patients' lateral jaw movements, but they have not been thoroughly investigated. This study compared recordings of immediate sideshift by using a pantograph and two intraoral registration materials. Pantographs were completed on 20 healthy participants by using chinpoint guidance and a kinematic hinge axis. Three lateral interocclusal records were completed on each participant and averaged for right and left sides. The average immediate sideshift recorded by a pantograph (0.54 mm) was less than that recorded by the two intraoral registration materials. The standard deviations were similar for all materials. An analysis of variance test identified significant statistical differences between a pantograph and one of the intraoral registration materials, but not between the pantograph and the other registration material. Immediate sideshift recorded with one material compared favorably with a pantograph recording when three records using the chinpoint guidance were averaged.
