PROBLEM TO BE SOLVED: To provide a post stand for dental technology on which a reduction fraction type model, where double-pin shape dowel pins called twin pins are embedded and a reduction fraction type model, where two single pins are embedded, can easily be placed. SOLUTION: A plurality of holes 2 for post planting and long holes 3 for the dowel pins are arranged in the upper surface of the post stand 1. The long holes 3 for the dowel pins are radially arranged by 90°with the cylindrical axis of the post stand 1 as a center, but can be arranged in other ways. The long holes 3 for the dowel pins are linearly drawn, but can be drawn as curved lines. The long holes 3 for the dowel pins are adequate when the depth is≥8 mm and they are either penetrating or not penetrating. COPYRIGHT: (C)2009,JPO&INPIT
