Abstract: This aims to produce dental sterilizing water having not only a sterilizing action but also an action to break a bio-film. Provided is a sterilizing water producing device (51) comprising a stock solution tank (3) for storing a stock solution (52), a stroke pump (4) connected in communication to the stock solution tank, an electrolytic bath (5) connected in communication to the stroke pump, a discharge pipe (6) connected in communication to the electrolytic bath, and a dilution water tank (8) reserving dilution water (57). The dilution water tank (8) is so positioned relative to the tip position of the discharge pipe (6) that the tip of the discharge pipe (6) may be lower than the water level of the dilution water (57) reserved in the dilution water tank (8). The stock solution (52) is prepared by selecting any of the methods shown at (a-1) to (d).

Abstract: There are provided an occlusal surface transfer instrument, an articulator, and an occlusal surface setting instrument capable of making an artificial tooth with a dentition adapted to patient's occlusal surface, and a method of making an artificial tooth by use of them. An occlusal surface transfer instrument 10 according to the present invention is constituted of: a bite material holding member 2 which holds a non-hardened bite material 1 in a bitable state; a connection member 3 whose one end is provided with the bite material holding member; a pupil line setting rod 4 disposed in the other end of the connection member, and a median line setting rod 5 which is attachable at right angles to the pupil line setting rod and in an arbitrary angular position around a material axis of the pupil line setting rod.
