Aim: Purpose of our research was to analyse the current trend in impression material as well as techniques used for fabrication for complete denture prosthesis amidst prosthodontists based in India. Methodology: Around 100 practicing prosthodontists participated in this questionnaire survey containing 16 close ended questions; where they were asked about their preference of material and methods for making complete denture impression. Statistical analyses were performed using the SPSS 25.0 (Statistical Package for the Social Sciences). Results: Majority of responses indicated use of irreversible hydrocolloid in stock metal tray for making the preliminary impression. The selective pressure was the mostly used impression technique (78.3%). The most common material for the fabrication of custom trays was autopolymerizing acrylic resin (96.7%). All respondents border molded the custom tray prior to making the final impression. The final impression materials used were zinc oxide eugenol impression paste (73.3%), polyvinylsiloxane (11.7%), polyether (11.7%) and polysulphide (3.3%).
