The purpose of this study is to establish an index in adjustment of occlusal height of a cast crown by the silicone-black method. Firstly, occlusal contact area in dentition was measured when occlusal height and proximal contacts of the molar tooth xvere varied. Secondly, validity of this index was investigated inadjustment of occlusal height of a cast crown.The results obtained were as follows : 1) In case that any the second premolar, the first molar, or the second molar was an abutment tooth, occlusal contacts of the mesial tooth close to them came into being only when occlusal height of a crown was made high less than 100 μm. 2) In case that any the first premolar was an abutment tooth, occlusal contacts of a contralateral one came into being only when occlusal height of a crown was made high less than 100 μm. 3) It was found that phenomena of l) and 2) were an useful index in adjustment of occlusalheight of a crown.
