To provide a polymerization apparatus for dental technology capable of carrying out effective polymerization with a reduced number of LED light sources to be used.

The polymerization apparatus 10 for dental technology, which cures a light curing material to be used for a dental prosthesis 1, comprises a housing 11; a partition wall 13 disposed in the housing so as to form a polymerization space A where polymerization is carried out; a rotating table 14, which is arranged on a lower side of the polymerization space and on which the dental prosthesis is disposed directly or via other members; and a plurality of LED light sources 15b, 15c which irradiate a light for the curing to a polymerization region B, which is formed on the upper side of the rotating table and where the dental prosthesis can be disposed, wherein at least one 15c of the plurality of LED light sources is disposed such that a light axis thereof is inclined obliquely upward to be directed toward the polymerization region.
