<p><P>PROBLEM TO BE SOLVED: To provide a blade for trituration of a vacuum agitator for dental craftsman, performing agitation and trituration of mixing materials such as implant, gypsum or impression material in dental surgery under reduced pressure without uneven kneading. <P>SOLUTION: In the agitator, materials blown up to an outside upper part by centrifugal force are moved downward by a return piece and incorporated by a trituration blade side edge in agitation and trituration. In the structure, a central staircase-like hole 7 is provided to thereby prevent powder and liquid such as implant from adhering to the central part of the trituration blade, so that uneven kneading is reduced. The blade for trituration is used to hold down uneven kneading to the minimum, so that kneading can be performed to hardly affect curing of contents. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
