Impression Materials


Impression materials are used to record the shape of the teeth and alveolar ridges. There are a wide variety of impression materials available each with their own properties, advantages and disadvantages. Materials in common use can be classified as elastic or non-elastic according to the ability of the set material to be withdrawn over undercuts.

Although there are many multiple use materials today (that is, materials that can be used for a variety of functions, such as removable prosthetcs and crown and bridge and implants) some single use materials are better suited to one’s practice. Materials such as compound and zinc oxide eugenol pastes are useful solely in removable prosthetics, primarily full dentures; the polyethers and polyvinyl siloxanes, while usable in removable prosthetics, are better suited to fixed prosthetics and implants.
