The aim: this study aimed to assess the awareness of dentists in Benghazi, Libya toward current impression materials and techniques used for complete denture construction.
Material and methods: Seventeen closed-ended questions were designed as anonymous self-administered questionnaires, and they were intended as a survey of current impression materials and techniques used by dentists in Benghazi to fabricate complete dentures. a questionnaire-based survey was confidentially conducted by a random distribution of 50 surveys among dentists in Benghazi.; out of which, 33 questionnaires were filled. Data were collected and analyzed using Statistical Package for Social Sciences (SPSS) version 25.0.
Results: 75.8% of the practitioners used stock plastic trays for primary impressions. The irreversible hydrocolloid (alginate) was the material of choice for preliminary impression by 72.7%. Most of the participants used light cure acrylic resin to fabricate custom-made trays (87.9%). Nearly 93.9% of responses indicated that the custom-made trays were preferred to be fabricated a couple of days before final impression making. The most common material to be used for border molding of the custom-made tray is the green stick impression compound (75.8%), followed by polyvinylsiloxane (putty) 24.2%. 45.5% of the respondents favoured the mucocompressive impression procedure. Almost more than half of the studied dentists are fans of zinc oxide and eugenol impression paste 51.5%, and polyvinylsiloxane (regular body) 33.3%. Conclusion: Within the limitation of this research, we can conclude that multiple choices of impression materials and techniques are available and convenient for the construction of complete dentures. However, the results showed that more conventional techniques for complete denture impression are adopted by dentists in Benghazi. The ideal materials and techniques are mandatory for successful complete denture fabrication.
