Claim:
A method for the manufacture of an impression-making spoon for dental use, adapted to accommodate the whole of a teeth arch, comprising: a tray for the impression-forming material, with a bottom and a shoulder; and a handle for manipulating the spoon; wherein said tray and said handle are formed by means of folding of a single sheet of cut laminar material with a central portion intended to form the bottom of the tray, a extension intended to form the handle and two symmetrical side portions intended to form the shoulders of the tray, characterized by: providing said sheet of laminar material with said two symmetrical side portions partially joined to said central portion along curved folding lines and having zones not joined to the central portion, each of said zones ending with a respective edge; folding the side portions along said curved folding lines until they are brought into a position approximately perpendicular to the central portion; and folding the zones of said side portions which are not joined to said central portion along a cylindrical surface until they complete the front zone of the tray shoulder by bringing said edges of the side portions in an end-to-end arrangement in the front zone of the spoon, opposite said handle.
