WIPO Patent Application WO/2011/056843
Kind Code:
A3
Abstract:
A dowel pin and sleeve combination for use with a tooth die that is part of a dental model includes a dowel pin and a sleeve that receives the pin. The dowel pin includes a tooth anchor section that is configured to be fixedly attached to the tooth die and a main body section having a bore formed therein. The main body section has a living hinge formed therein that partitions the main body section into an upper pivotable portion that pivots about the hinge and a lower portion. A section of the bore is threaded and the main body section includes an urging member that travels along the threaded bore section and can be driven into contact with the pivotable portion of the main body section. The bore forms an entrance into the slot that defines the living hinge to permit the urging member to be driven into contact with the pivotable portion. The pin includes a locating member extending radially outward from the main body section. The locating member is shaped to indicate a pivot direction of the tooth die and therefore a direction of intended tooth movement. The sleeve is for fixation in a base of the model and has a central bore formed therein that is configured to receive the pin.
