Introduction: With the increased popularity of implants, orthodontists are in search of a better material. Titanium-gold (Ti-Au) is a newer material and could be a choice to replace the currently popular titanium-aluminum-vanadium (Ti-6Al-4Va) alloy. Materials and Methods: Using the finite element analysis method, three-dimensional computer-aided models of a mini-implant was designed. Two cylindrical bone pieces into which the implant was inserted were used. A force magnitude of 5 N was then horizontally and separately applied to the implant head. Results: Comparison of the maximum von Mises stress in the implants of Ti-6Al-4Va and Ti-Au was done. The maximum stress value of 252.356 and 242.415 Mpa, as well as maximum deformation of 0.025 mm and 0.019 mm, on Ti-6Al-4Va and Ti-Au can be observed, respectively. Conclusion: It was found that the maximum stress and maximum deformation values were lower in Ti-Au as compared to Ti-6Al-4Va implant. As the Ti-Au implant has greater resistance to deformation, it can be concluded that this newer alloy has better strength than Ti-6Al-4Va implant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
