Title: Modelling tool for denture wax patterns - with fingertip release collet and heating element
Inventor: HOMBRECHER FRITZ
IPC: A61C13/00
Filed: 1979-12-24
Abstract: A modelling tool for sculpture work on wax models for the mfr. of partial or complete artificial dentures consists of a plastic cylinder which carries at the forward end a tapered clamping device with a collet for the shaft of a modelling blade or spatula. A collar at the other end can be operated by a thumb to push the shaft forward and release the hot blade. A spring normally pulls the collet back into the clamping device to retain the tool. An alternative way to the extraneous heating of the blades is an internal heating coil so that the tool can be used for soldering. This greatly facilitates the frequently necessary change of modelling tools. The tool can be produced at low cost. It saves waiting for heating up after a change.
