The purpose of this study is to estimate the reproducibility of the intercuspation of articulated casts using the silicone bite-impression technique compared with the conventional technique. Using 6 crown cases of the mandibular first molar, the occlusal height and the occlusal contacts reproduced by each technique were measured with the 1P-Checker and articulating paper. For the conventional technique the variation of the hand articulation was also measured.The following results were obtained.1.The occlusal height of the silicone bite-impression technique showed lower and narrower scattering than the conventional technique.2.The reproducibility of the occlusal contacts showed high in the silicone bite-impression technique but low in the conventional technique. For the conventional technique, depending on the cusp inclination, as the cusp inclination became steep, it showed high. The silicone bite-impression technique was not influenced very much and proved to be superior to the conventional technique with regard to the reproducibility of the intercuspation and its stability.3.The hand articulation in the conventional technique showed narrow variation for the steep cusp inclination, but wide variation for the gentle cusp inclination and could have an influence on the reproducibility of the intercuspation.
