    Background: The growing demands from clinicians and patients to optimize the dental implant treatment protocols require the fabrication of a precisely fitting implant-supported prosthesis, the prerequisite of which is the accuracy of the implant impression. The objectives of this study were to determine the knowledge, attitude, and practice of dental students and dental practitioners on impression materials for implant placement. In particular, this study investigated the most accepted impression material used for making impressions for dental implants among these practitioners and students and their opinions regarding the clinical factors that may influence the decision-making process for the selection of the impression material. Materials and Methods: An online questionnaire was sent to dental students and practitioners in Saveetha Dental College. Returned responses were subjected to qualitative and quantitative analysis. Differences in groups were examined using Chi-squared test for linear trends across the rated questions and cross-tabulations to compare responses from different groups. The level of significance was set at P < 0.05. Results: A total of 100 dental implant practitioners responded to this survey. The majority of respondents (71%) preferred addition silicone and polyether as an impression material, and about an equal number of respondents believed that dimensional stability and elasticity are ideal requisites for impression materials (32%). Most of the clinicians (89%) felt that the most accurate impression material technique for subgingival implants is the usage of putty and light body combination vinyl polysiloxane impression material. In case of non-parallel multiple implants, the majority of dentists (46%) chose open tray technique with polyvinyl siloxane (PVS) as the choice of impression material and technique and 22% preferred closed tray with PVS. Significant relationships between the choice of impression material and the qualification of the respondents were noted. Conclusions: The current survey concludes that addition silicone and polyether are the most commonly used impression materials, the presence of angulated implants and subgingival implants affects the choice of impression material and technique, and elasticity and dimensional stability are the most important requisites of an impression material for implants. Therefore, it can be understood that most of the dental students and practitioners followed the well-documented techniques and proven materials.
