A complete denture is an artificial prosthetic device that replaces the entire dentition and associated structures of the maxilla or the mandible. There exists consensus that to obtain a successful complete denture it is necessary to have support, stability and retention. It starts from an adequate preliminary impression, that allows building the individual trays, performing peripheral sealing of the individual tray to final impressions with great detail and accuracy. A peripheral sealing and an adequate extension of removable prostheses helps to acomplish a “triad of equilibrium” characterised by good retention, support and stability. The aim of this study was to identify the current trends in impressions for complete dentures made in post-graduate programs in Prosthodontics in the Iberian Peninsula; establishing the most used impression techniques as well as establishing which biomaterials are the most frequently used, through a survey sent by e-mail to postgraduate directors in Prosthodontics in Iberian Peninsula. This survey comprised 24 questions, divided into two parts. Although there have been limitations due to the lack of some answers to certain questions, which may have had an influence on the possible statistical inference of the results of this survey, it was found that: largely, the techniques and materials used were similar both in Portugal and Spain. Nevertheless, it was found that there are some differences, such as the type of tray used in the preliminary impression and the material used for final impressions. There aren’t any studies of this kind in the Iberian Peninsula and from the academic point of view it was found that most of the techniques and materials used in the Iberian Peninsula are similar to those found in the postgraduate prosthodontic programs in the United States of America.
