The device comprises a tube 2 formed of surgical mesh with a closed end 4 and a filling end 5 including an opening 6. In use the tube is packed with impression material forming a package. The package is located in an edentulous region of a patients jaw and teeth (figs 3 & 4) particularly where two or more adjacent teeth are missing. Further impression material may be dispensed from a conventional dispensing gun onto the upper surface of the package and the occlusal surfaces of the subject's remaining teeth. When the material has set the resulting bite registration (9, fig 6) is removed.
