ABSTRACT

A duplication method of the old dentures has been shown to be an effective technique of making total prostheses at patients in third age of their lives. The making of new total prostheses by denture duplication method is conducted according to protocol of three clinical visits and two laboratory phases. Selection of the box tray is done according the old denture. Then wax sprue is placed posteriorly. Next the denture is impressed with irreversible hydrocolloid on the outside, and the inside with silicone material and then we apply plaster, through previously posted retention elements. After separate the denture from both impressions, the mould is filled with molten wax. On the received wax replica, wax teeth are replaced with acrylic teeth resulting with new wax trial denture. Finally after the functional impression and convencional procedures new denture is obtained. In this way the patient has positively adjusted to the new prosthetic solution in the form of “new prosthesis”. Thus the problems, which would occur as result of errors during the de novo making are avoided.
