Abstract

The purpose of this study was to investigate the accuracy of interocclusal recording materials that reproduced intercuspation on mounting stone casts. A bridge type reference model, which could not maintain stable intercuspation without interocclusal records, was selected. The reference model was mounted on an articulator. Interocclusal records were taken on the reference model. The reference model could be separated from the articulator when interocclusal records were measured. For interocclusal records, which were made from PRESIDENT JET BITE, EXABITE, RAMITEC, Xantano, and NEW PLASTONE between the upper and lower reference models, the occlusal heights of the reference model on the left molar of the abutment side, anterior teeth, and right molar were measured using an IP-Checker. The PRESIDENT JET BITE, EXABITE, and RAMITEC elastic materials were studied to determine the influence on the recording range.<BR>The results were as follows:<BR>1. The occlusal height was higher for the left molar than the other sides when the recording range was the abutments; the occlusal height was higher for the left molar and the anterior teeth than for the right molar when the recording range was 1/3 dentition.<BR>2. The occlusal height of the elastic materials was lower than the nonelastic materials.<BR>3. The results suggested that interocclusal records made from addition type silicone rubber impression materials have the best reproducibility of intercuspation and a smaller recording range has greater reproducibility of intercuspation.
