Effect of Tooth Element Retention and Acrylic Resin Brand on the Tensile Bond Strength with Denture Base

Abstract

Teeth have a role that is very much needed for humans. Without teeth, some functions of teeth can be disrupted. Disorders that occur due to tooth loss can be prevented by making dentures to replace missing teeth. In dentures, adequate bonding between the acrylic tooth elements and the denture base is necessary to increase the strength and durability of the denture. Purpose: This aim of this study was to understand the effect of the shape of the retained tooth elements and type of acrylic brand on bond strength tensile denture base acrylic resin. Methods: This was an experimental laboratory study research. There were 36 specimens in this study from two brands of acrylic resin. Specimens were divided into three groups, namely the group without retention, slope retention, and groove retention respectively. Specimen testing was carried out using a universal testing machine brand Shimadzu AG-X plus. The data obtained was analyzed using bivariate Two Way ANOVA test. Results: The research indicates a significant difference (p<0.05) in tensile bond strength for the Vertex brand acrylic resin (0.001). Within the Vertex brand, the slope retention group showed a significant difference (p<0.05) of 0.017, and the groove group showed a significant difference of 0.003 in the denture elements. Conclusion. It conclusion, there is a significant impact of the vertex brand acrylic resin material compared to the twin cure base acrylic material on the tensile bond strength of dental elements with a denture base while the form of retention has no significant influence.
