Retention Capacity of Original Denture Adhesives and White Brands for Conventional Complete Dentures: An In Vitro Study

(1) Introduction: Denture adhesives (DAs) promote stability, chewing ability, and quality of life. The objective of this study was to compare the effectiveness of original brand DAs and white brands in their retention of conventional complete dentures. (2) Methods: This study followed the recommendations of the international standard ISO 10873. Three original brands of DA (Corega (R) Fixacao 3D, GlaxoSmithKline (R), Stafford Miller Ltd., Dungarvan Co. Waterford, Ireland), KuKident (R) Pro Procter & Gamble Technical Centres (R), Ltd., Whitehal Lane, Germany and Elgydium (R) Fix, Laboratorios URGO (R) SL, Florida, Spain) were compared to three white brands (Fixacao Extra Forte Pingo Doce (R), Laboratorios Cosmodent (R), Cantabria, Spain), Fixador de Proteses (Continente (R), Propack (R), Gmbh, Ladenburg, Germany) and Creme Fixador de Proteses (Auchan (R), Ellipse (R), Roubaix, France). Their retention capacities were analyzed using a mechanical test device. (3) Results: The mean retentive ability of original brand adhesives (M = 11.16, SD = 5.27) was significantly higher (t(298) = 11.88; p < 0.001) than that of the white brands (M = 5.92, SD = 1.18). When comparing all brands, statistically significant differences were also observed, F(5.294) = 707.68 (p < 0.001). The generic adhesive results were more homogeneous. The generic brands from Continente (R) (M = 5.24, SD = 0.94) and Auchan (R) (M = 5.80, SD = 0.79) were not significantly different, while the Pingo Doce (R) brand obtained significantly higher mean retention results (M = 6.71, SD = 1.28). (4) Conclusions: The original brands of DA have a significantly higher retentive ability than the white brands. Elygidim (R) Fix had the worst result of the three original brands, and the product from Pingo Doce (R) had the best result among the three white brands.

Automated summary

Original brands of denture adhesives have significantly higher retention ability than white brands. Among the three original brands, Elygidim (R) Fix had the worst result, while the product from Pingo Doce (R) performed the best among the three white brands.
