摘要： A dental implant includes a male threading part and an implantation torque increasing part from the tip side. The male threading part includes multiple threading parts that have the same lead but different pitches, with the pitch increasing toward the tip side. The outer diameter of the male threading part is constant or increases toward the implantation torque increasing part. The implantation torque increasing part includes thread crests that have a different lead from the lead of the male threading part or a projecting row that is continuous circumferentially. In cross-section, a contour line connecting tops of the thread crests of the threading part that is adjacent to the implantation torque increasing part is a straight line, and the tops of the thread crests or the top of the projecting row of the implantation torque increasing part are located on an extension line of the contour line.

摘要： The present invention relates to a color adapting composition used for coloring and color adapting porcelain for ceramic crown such as dental restorations and prosthetics, and aluminosilicate glass appropriate for using in a color adapting composition. More specifically, a color adapting composition for dental porcelains are prepared by blending two or more kinds of glass frits having different sintering temperatures from each other and an inorganic pigment or a colored glass obtained by previously dispersing inorganic pigments in glass.

摘要： The present invention relates to a tooth which is used in a dental arch model with which dental students can experience dental works in the oral cavity and practice treatments. More specifically, the present invention relates to a tooth composition for formation trainings such as abutment tooth formation and cavity preparation. Since conventionally used dental arch models have a grinding sensation different from a natural tooth, dental students having completed formation trainings such as abutment tooth formation and cavity preparation by using these conventional models are frequently puzzled to have different grinding and handling properties upon dental works in the oral cavity in practice. That is, these conventional dental arch models are largely different from a natural tooth in grinding sensation including slipperiness and easiness in grinding. A tooth for a dental arch model simulating the enamel texture and the dentin texture constituting a natural tooth whereby even the difference in grinding sensation between the enamel texture and the dentin texture constituting a natural tooth can be reproduced by forming at least the enamel portion with the use of a sintered body of an inorganic powder such as alumina.
