DEVICE FOR MAKING POSITIVE REPRODUCTIONS OF DENTAL IMPRESSIONS

摘要

This device for producing positive reproductions of dental impressions comprises a frame on which a mixer assembly (10) capable of preparing the plaster in liquid form necessary for producing the positive reproduction of the impression can be fitted. . The mixer assembly (10) comprises a reservoir, open at both ends, intended to receive a dose of powdered plaster, and an agitator, adapted to be received in the reservoir and to produce the plaster in liquid form in cooperation with the reservoir, said agitator being configured to close the lower opening of the reservoir. The mixer assembly (10) is received reversibly within the frame in order to couple the stirrer to a motor with which the frame is provided and thus ensure the rotation of said stirrer. The frame comprises a member able to move the stirrer vertically with respect to the tank, in order to release the lower opening of the said tank and allow the flow by gravity of the plaster then obtained in liquid form.
