Mode of Bond Failure Between 3D-Printed Denture Teeth and Printed Resin Base Material: Effect of Fabrication Technique and Dynamic Loading. An In Vitro Study

Abstract

The fabrication technique has an influence on the mode of failure between acrylic teeth and resin base material. Cohesive failure in teeth was predominant in the conventional group, suggesting possibly higher bond strength between the teeth and resin base in this group. The observed failure modes reveal that both fabrication techniques exhibited satisfactory bond strength. Chewing simulation did not significantly influence the bond strength of any of the tested groups.
