Abstract

The purpose of this study was to investigate the accuracy of interocclusal recording addition-type silicone rubber impression 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, Stat·BR, BITESIL, MEMOSIL, and MUSHPRINT 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. In addition, the relationship of the reproducibility of intercuspation and the mechanical properties of materials was studied.<BR>The results were as follows:<BR>1. The occlusal height on the left molar was high; the occlusal height on the anterior teeth and the rightmolar were unchanged or low when the recording range was on the abutments. The occlusal height on the left molar and the anterior teeth were high; the occlusal height on the right molar was unchanged when the recording range was 1/3 of the dentition.<BR>2. The reproducibility of intercuspation of the interocclusal recording addition-type silicone rubber impression materials was excellent; however, MEMOSIL was inferior to the other materials. The occlusal height on the anterior teeth was greatly influenced by the recording range when BITESIL and MEMOSIL were used.<BR>3. It was surmised that the reproducibility of intercuspation was influenced by the compression set and the dimensional change of the interocclusal recording addition-type silicone rubber impression materials.
