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%).

Additive Manufacturing has brought a paradigm shift in manufacturing trends
in terms of material flexibility, accuracy, lead time and product cost. There are myriad of
additive manufacturing technologies which are commercially available but Fused
Deposition Modeling (FDM) has outclassed others due to its unique capabilities. The paper
aims to present the critical analysis of materials, applications and recent advancements in
the area of FDM. The inception of additive manufacturing processes along with their
aggressive development in field of new product development and customized parts is also
highlighted. A detailed literature survey has been carried out to chalk out various materials
and advantages of FDM. An analysis using VOSviewer software has been carried to
highlight the major areas where an intensive research has been performed. It has been
noticed that limited research has been performed on development of functionally graded
material. Moreover, the effect of temperature on different additive manufacturing
processes must explored in future.
