EFFECT OF FOUR TYPES OF DENTURE ADHESIVES ON RETENTION OF MILLED DENTURE BASE ACRYLIC RESIN

Abstract

As the population ages and tooth loss becomes more common, complete dentures become more essential. Therefore, the retention of removable dentures is a primary concern for many patients. As a result, denture wearers frequently use denture adhesives to enhance the functioning of full dentures. We examine the retention strength of four commercial brands (eight formulation) cream-type denture adhesives on milled denture base acrylic resin. Eight milled acrylic resin molds were created for this purpose in accordance with ISO 10873:2021, and ten times of the retention strength test of eight denture adhesives - Fittydent (Ft), Fixodent Original (FxO), Fixodent Microseal for Partials (FxM), Fixodent PLUS Best Foodseal Technology (FxFS), Fixodent Plus Best Hold (FxBH), Fixodent Ultra Max Hold (FxMH), Olivafix (O) and Polident (P). The analysis of variance (ANOVA) and LSD multiple comparison post hoc test were used to statistically evaluate the findings of the study at a 95% level of significance. There were statistically significant (p < 0.05) differences in mean retention strength between the groups of denture adhesives. The Ft, O and P groups had statistically significant (p < 0.05) differences to every other group. There was no significant difference between the Fixodent groups. The Ft and FxFS groups, respectively, had the lowest and highest retention strengths. There were no differences between any of the Fixodent groups and these adhesives had a greater retention strength than Ft, O, and P. The authors advised using P because it delivered maximum efficiency assessed in kPa/THB or FxO because it offered the lowest cost per gram of adhesive in the highest retention category.
