Comparative analysis of the bond strength of digital denture base materials.
Purpose: Evaluate the bond strength of commercial digital denture base materials to denture teeth and characterize composite resins.
Materials and methods: Twenty-four square-shaped specimens were prepared from Lucitone 199 denture base disc (Dentsply Sirona), AvaDent denture base puck (AvaDent), KeyMill denture base disc (Keystone), Lucitone digital print denture base resin (Dentsply Sirona), Formlabs denture base resin (Formlabs), and Dentca denture base resin II (Dentca) to test the bond strength to manufacturer-recommended denture teeth and characterize composite resin. Bond strength was determined using the shear bond test. Data were analyzed using one-way ANOVA followed by Tukey's HSD test (α = 0.05). Failure mode for all debonded specimens was analyzed using a stereomicroscope.
Results: The milled bases exhibited better bonding to manufacturer-recommended denture teeth but showed a low bond strength to the characterizing composite resin. In contrast, the printed bases showed a low bond strength to the manufacturer-recommended denture teeth material but displayed a better bond strength to the characterizing composite resin. The difference was statistically significant (p < 0.05).
Conclusion: This study demonstrates that the bond strength of milled denture bases to the manufacturer-recommended denture teeth is higher compared to that of printed denture bases, except for Lucitone 3D, which exhibited significantly higher bond strength when using Digital Fuse techniques. Future research should investigate surface modification strategies to improve long-term durability of bonds between denture bases and both denture teeth, and characterize composite resins as achieving reliable bonding to digital denture bases remains a clinical concern.
期刊介绍:
The Journal of Prosthodontics promotes the advanced study and practice of prosthodontics, implant, esthetic, and reconstructive dentistry. It is the official journal of the American College of Prosthodontists, the American Dental Association-recognized voice of the Specialty of Prosthodontics. The journal publishes evidence-based original scientific articles presenting information that is relevant and useful to prosthodontists. Additionally, it publishes reports of innovative techniques, new instructional methodologies, and instructive clinical reports with an interdisciplinary flair. The journal is particularly focused on promoting the study and use of cutting-edge technology and positioning prosthodontists as the early-adopters of new technology in the dental community.
