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%).

Using the method of scanning electron microscopy learned the
state of the surface of dentures and the oral mucosa in individuals that
intolerant to acrylic dentures.
It was found that in case of intolerance to acrylic dentures significant
accumulation of microorganisms and their proliferation are determined on the
surface of the prosthetics in contact with the oral mucosa.
These microorganisms along with micro trauma of the surface of the oral
mucosa may be one of the etiological factors in the development of
intolerance to acrylic dentures.

In the past, the ingredients used for the denture bases were formaldehyde of vulcanite, celluloid & phenol. Around 1930's, acrylic resins were brought into dental work. There are other disadvantages of acrylics, such as residual monomer sensitivity, weak mechanical resistance, low fatigue power, fragile on contact, weak heat conductors, low stiffness, strong thermal expansion coefficient, thermal shrinkage, bad color consistency of self-curing resins, porosity, craziness, warpage, poor metal and porcelain adhesion and mechanical retaining criteria. But they are also the most commonly used products of the denture foundation to date. The aim of this literature review was to examine the established works on denture-based resources for the manufacture of full dentures and provide historical context, current status, and potential perspectives on evolving technologies to the reader. The analysis of many dentures provides an overview of the various developments in this field. The polymers, particularly the acrylic resins, are constantly changing and the materials of choice after being in this field more than 65 year.

Aim: The aim of the study is to evaluate the frequency of the number of patients who undergo maxillary single complete denture in a private dental college, Chennai.
Materials and Methods: The data were reviewed from patient records in a private dental college from a particular time period of June 2019 to March 2020. The data collected was then tabulated in excel and exported to SPSS by IBM. The outputs were obtained through statistical analysis..
Results: The results obtained were based on age, the most common age groups found were 44- 49 years. Based on gender, the gender predilection was towards females. The total number of patients who were diagnosed was greater than the number of patients who underwent treatment ( 51.2%) Conclusion: Within the limits of the study, the maxillary complete dentures are the most prevalent in the female gender of the age group 44-49 years of age. The number of patients treated were less compared to the number of patients diagnosed with partial edentulous maxilla.
