Study of the acceptability of lateral interocclusal records by a modular articulator

Semiadjustable articulators are extensively used for routine restorative procedures. The instruments may be adjusted by lateral interocclusal records. However, it has been reported that semiadjustable articulators do not accept lateral interocclusal records from all patients. The Hanau modular system 194 semiadjustable articulator was introduced to develop occlusion with minimal error. The manufacturer recommends that the instrument should be adjusted by means of lateral interocclusal records. This study investigated the acceptability of lateral interocclusal records. Sixty lateral interocclusal records were made for 30 edentulous subjects, and the acceptability of the records was evaluated by use of the split-cast mounting procedure. Out of 60 lateral interocclusal records, 52 (87%) records were accepted by the articulator. A Z test was used for two proportions and was statistically significant (p < 0.05).
