Abstract: Process of making a post for inserting a false tooth in a vacant space between first and second good teeth having the following steps. Cut first and second small indentations in the sides of each first and second good tooth facing the vacant space. Make a plaster model of the first and second good teeth. Insert wax in the gum saddle between the two existing teeth of the model. Insert pontic having interior and exterior portions, one portion having a first wing and the other portion having a second wing. Apply wax to the first wing so that it extends into the first indentation. Apply wax to the second wing so that it extends into the second indentation. Remove the pontic portions separately with the wax attached to them with the saddle wax adhering to the lingual pontic portion. Cast each pontic portion separately by the lost wax process. Whereby the two castings may be inserted separately in the first and second indentations and fastened together.
