An objective of the present invention is to provide a holder of an abutment tooth model to surely and accurately set a model of an abutment tooth on a three-dimensional coordinates measuring apparatus when measuring an outer face shape of the abutment tooth model by the three-dimensional coordinates measuring apparatus, where the holder of an abutment tooth model can easily hold an abutment tooth model, and can easily adjust and confirm an accurate position of the abutment tooth model. The holder includes an abutment tooth model holding base 1 and a cylindrical body 2. The abutment tooth model holding base 1 is formed in a pillar shape, has a concave part at the upper side thereof and a holding hole provided at a center of an end face of the lower side thereof for inserting a supporting shaft which projects at a center of a rotating part of a three-dimensional coordinates measuring apparatus, and can attachable/detachable hold the residual ridge side of an abutment tooth model by adhesion with a sticky material built on a bottom face in the concave part thereof. The cylindrical body 2 is formed in a cylindrical shape, and has a lower side thereof having a slightly larger inner diameter than an outer diameter of the abutment tooth model holding base 1 and being externally fitted to the abutment tooth model holding base, a stepped part, which contacts to a part or the whole of upper face of the abutment tooth model holding base 1, and an upper side from the stepped part having a smaller inner diameter than that of the lower side thereof.
