ABSTRACT:
Disclosed is a tool for turning a hex screw at the top of a denture compress containing denture flasks which comprises a hex key wrench having a shaft of finite length. Turning the hex screw in one direction causes pressure to be applied to a plate beneath it, and to the denture flasks within the compress. At one end of the shaft there is a handle perpendicular to the shaft, a T-handle. At the opposite end of the shaft a plurality of hex keys of different sizes are formed, in a contiguous relationship, the largest hex key being closest to the shaft and the smallest being furthest from the shaft. The T-handled hex key is supported by a frame which is attached to a flat base plate. The frame is perpendicular to the plane of the base plate, which has either within its surface or on its surface means for temporarily securing the dental compress thereto.
