The present invention relates to a device for supporting a partial denture on a front tooth or a molar tooth. A fixture member fixedly mounted on a supporting tooth crown is provided with a supporting member. A movable member formed of a shape memory alloy carrying out the martensite-transformation so as to be engageable and disengageable with the fixture member comprises a base portion to be fixedly mounted on the denture and movable portions which are subjected to the martensite-transformation to be transformed into a memorized form, thereby being engaged with the supporting member.
