Prediction of tribocorrosion processes in titanium-based dental implants using acoustic emission technique: Initial outcome

RETRACTED: Titanium and titanium alloys in dentistry: Current trends, recent developments, and future prospects

“…The metal ion release causes corrosion-related biological problems, such as toxicity, carcinogenicity, and hypersensitivity. The discharge of metal elements from the implant material to different body organs and peri-implant tissues was caused by biocorrosion, tribocorrosion, and their combination, which is a natural occurrence in the oral setting ( Barão et al., 2021 ). While biofilms or high fluoride concentrations are existent, this effect is amplified.…”

A review in titanium-zirconium binary alloy for use in dental implants: Is there an ideal Ti-Zr composing ratio?

“…It can be concluded that the contribution to hardness increase made by heat treatment and air cooling is essential because the Ti-Zr alloys (5, 10, and 15 wt. %Zr) did not show significantly different hardness with Ti when there was no further process after hot swaging in the study of Correa et al [26] compared with the studies of Cordeiro et al [23] , [24] and Barão et al [25] . In addition to the hardness, the elastic modulus related to alloy hardening was also increased by the processes performed after swaging.…”

“…Cordeiro et al found that all Ti-Zr alloys (5, 10, and 15 wt. %Zr) had statistically more significant hardness than that of Ti or even Ti-6Al-4 V. The increase in the hardness of Ti-Zr alloys is a consequence of solid-solution hardening generated by the α phase and grain refining caused by the thermo-mechanical process (homogenization and air cooling) [23] , [24] , [25] . By contrast, Correa et al found no difference in hardness for Ti-5, 10, 15 wt.…”

“…Regarding the chemical and electrochemical corrosion resistance capability, Ti-5 and −15 wt. %Zr performed the best [23] , [24] , [25] , [27] . Corrosion resistance is a significant factor that influences the longevity of implants and the harmfulness of the corrosion processes occurring in the body.…”

Minimization of Adverse Effects Associated with Dental Alloys

“…However, many studies use artificial saliva with additional components such as fluoride, lisozyme or urea [ 83 ]. In addition, experimental models reproducing saliva flow [ 38 ] or tribocorrosion [ 104 ] were introduced.…”
