A STUDY OF INTEROCCLUSAL ECCENTRIC PROTRUSIVE JAW RELATION RECORDS
Abstract:
Several aspects of interocclusal eccentric protrusive jaw relation records were studied to help clarify the value of their use. The findings of this study were Five dentists did not adjust the horizontal condylar tracks of the articulator to the same setting using the same protrusive record. The variations tended to increase as the amount of protrusion decreased. The adjustment of several protrusive interocclusal eccentric jaw relation records of the same subject did not accurately repeat the same setting of the horizontal condylar tracks of the articulator. The variations that did occur were believed to be due to error in the adjustment of the articulator, differences in position and possibly to muscle tensions while the records were being made.
