“…The TiO 2 film possesses a high corrosion resistance in various test solutions, such as artificial saliva, Ringer's solution, 0.9 % NaCl solution, or physiological saline solution [54,55]. Nevertheless, the protective TiO 2 film can degrade in the oral cavity in the presence of corrosive substances such as fluorides, lactic acid, carbamide peroxide (urea peroxide), and hydrogen peroxide [10,[54][55][56]103]. The breakdown of the titanium passive film leads to a localized corrosion failure such as intergranular attack, pitting, or corrosion fatigue [101,104].…”

The oral cavity is a complex environment where corrosive substances from dietary, human saliva, and oral biofilms may accumulate in retentive areas of dental implant systems and prostheses promoting corrosion at their surfaces. Additionally, during mastication, micromovements may occur between prosthetic joints causing a relative motion between contacting surfaces, leading to wear. Both processes (wear and corrosion) result in a biotribocorrosion system once that occurs in contact with biological tissues and fluids. This review paper is focused on the aspects related to the corrosion and wear behavior of titanium-based structures in the oral environment. Furthermore, the clinical relevance of the oral environment is focused on the harmful effect that acidic substances and biofilms, formed in human saliva, may have on titanium surfaces. In fact, a progressive degradation of titanium by wear and corrosion (tribocorrosion) mechanisms can take place affecting the performance of titanium-based implant and prostheses. Also, the formation of wear debris and metallic ions due to the tribocorrosion phenomena can become toxic for human tissues. This review gathers knowledge from areas like materials sciences, microbiology, and dentistry contributing to a better understanding of bio-tribocorrosion processes in the oral environment.

“…[23][24][25][26][27][28][29][30][31] Thomson-Neal et al 42 have reported that 3 ppm NaF is sufficient to tarnish the surface of Ti while autoclaving the Ti implants. Oshida et al 33 have reported that commercially available fluoride treatment agent could cause discoloration of Ti-6Al-4V brackets. According to Schutz and Thomas, 43 20 ppm of NaF may destroy the protective oxide layer on Ti while Nakagawa et al 27 have reported such an occurrence at 30 ppm of NaF.…”

“…Many commercially available fluorinated gels contain very high concentrations of fluoride ions, up to 10,000 ppm, with a pH, ranging between 7.2 and 3.2. 28,33 Such a high concentration of fluoride ions would have a deleterious influence on the corrosion resistance of Ti alloys. Hence, it is essential to understand the electrochemical behaviour of Ti alloys in fluoride medium.…”

“…In the literature, most studies use fluorides diluted in Fusayama's artificial saliva solutions at pH 5, to simulate the oral environment in terms of corrosion behavior. Therapeutic bleaching agents based on carbamide (urea) or hydrogen peroxide has also been shown to affect the corrosion resistance of titanium . In the present study, 35% hydrogen peroxide at pH 7 was applied onto the implant system surface.…”

Objective The aim of this study was to evaluate surface changes on dental implant systems and ions release after immersion in fluoride and hydrogen peroxide. Methods Ten implant‐abutment assemblies were embedded in acrylic resin and cross‐sectioned along the implant vertical axis. Samples were wet ground and polished. Delimited areas of groups of samples were immersed in 1.23% sodium fluoride gel (F) or in 35% hydrogen peroxide (HP) for 16 min. Gels (n = 3) were collected from the implant surfaces and analyzed by inductively coupled plasma mass spectrometry (ICP‐MS), to detect the concentration of metallic ions released from the implant systems. Selected areas of the abutment and implant (n = 15) were analyzed by atomic force microscopy (AFM) and scanning electron microscopy (SEM). Results SEM images revealed surface topographic changes on implant‐abutment joints after immersion in fluoride. Implants showed excessive oxidation within loss of material, while abutment surfaces revealed intergranular corrosion after immersion in fluoride. ICP‐MS results revealed a high concentration of Ti, Al, V ions in fluoride after contact with the implant systems. Localized corrosion of implant systems could not be detected by SEM after immersion in hydrogen peroxide although the profilometry showed increase in roughness. ICP‐MS showed the release of metallic ions in hydrogen peroxide medium after contact with dental implants. Conclusion Therapeutical substances such as fluorides and hydrogen peroxide can promote the degradation of titanium‐based dental implant and abutments leading to the release of toxic ions.
