ABSTRACT:
In order to solve such problem that heating a mark such as a one-chip microprocessor which is easily damaged thermally in case of curing a heat-curing resin enclosing such one-chip microprocessor could have not been essentially made in event of embedding sealably such mark in the resin section of a denture, the present invention is characterized by that a groove-shaped recess for inserting the mark has previously been defined in a wax pattern indispensable for fabrication of the denture. For defining such recess, the implement for making a recess for embedding sealably the mark which is provided with a head shaped so as to have substantially the same dimension as that of the mark is used. More specifically, the head of the implement which has been heated by hot water is pressed upon a surface of the wax pattern to define such a groove-shaped recess as a result of melting a portion of the wax thus heated. Then, a heat-curing resin is poured into the recess defined in the wax pattern, whereby a cured resin section containing the recess is shaped. Thereafter the mark is inserted into the groove-shaped recess, and then a gap defined around the mark and an exposed portion of the mark is covered with a resin used for direct restoration which cures instantly at ordinary temperatures, or a photo-polymerizing resin to sealably embed the gap and the exposed part of the mark. When a one-chip microprocessor transmitting identification number us utilized as a mark and is embedded in the resin section of such denture, the resulting denture can be identified simply and positively. As a result, management for dentures becomes very easy un dentist's or dental mechanic's office.
