A Survey on Commonly Followed Impression Techniques and Materials in Complete Denture Fabrication

Abstract

This study aims to investigate the prevailing practices in complete denture fabrication by examining the choice of impression techniques and materials among dental clinicians and students. A comprehensive survey was conducted involving 140 participants, revealing that 86.4% favor zinc oxide eugenol, while 13.6% opt for impression compound; intriguingly, none utilize impression plaster. The rationale behind the predominant use of zinc oxide eugenol was diverse, with 86.4% emphasizing its ability to record fine details, 38.6% highlighting patient comfort, and 33.6% considering its cost-effectiveness. Edentulism, particularly among those aged 65 and older, presents a substantial oral health challenge. Complete dentures stand as a primary solution to restore both function and aesthetics for this demographic. At the core of denture fabrication lies the impression-making process, a crucial step influencing the ultimate success of the prosthetic intervention. This study delves into the dynamic landscape of impression materials and techniques, acknowledging the historical use of traditional materials like alginate and impression compound. However, it also recognizes the contemporary shift towards elastomeric materials such as polyvinylsiloxane and polyether, heralding enhanced properties in terms of dimensional accuracy, elastic recovery, and ease of use. The objectives of this survey encompass understanding the prevalent choices made by dental clinicians and students, dissecting the factors that drive these preferences, and shedding light on the evolving landscape of complete denture fabrication. The findings not only reveal a predominant inclination towards zinc oxide eugenol but also unveil the nuanced reasoning behind this preference. This survey contributes valuable insights into current practices, offering a foundation for future research directions, educational enhancements, and potential advancements in the field of complete denture prosthetics.
