Assessment of the properties of locally produced impression compound


Background: The goal of this study was the production of new type of impression compound that meets the ADA specifications along with being cheap and available in the local market.Materials and Methods: The basic ingredients were similar to those used by the commercially available products (Harvard, QD and Vevey). Specific properties were tested, like visual inspection, flow, reproduction of details, compatibility with stone, thermal expansion, and repeated use expiration.Results: The study proved that the new impression was within the limit of the American Dental Association specification No.3. (ADA No.3) (1), hence it could be used sufficiently.Conclusion: The use of the new impression compound for dental purpose is advised. Yet the reuse of the same product again and again is not advised because of the deterioration of the impression compound properties
