Bio-tribocorrosion in dental applications

Determining the relative importance of titania nanotubes characteristics on bone implant surface performance: A quality by design study with a fuzzy approach

“…Therefore, hardness was found to be the seventh most important mechanical CQA. Hard materials provide a better protection to wear [165], and reduce the probability of corrosion [166]. However, increased hardness can reduce ductility and toughness [166].…”

Tribological characteristics of dental metal biomaterials

“…In addition to this, almost 10% of dental bridges are damaged due to corrosive wear or tooth scale. According to Roch et al [11], tribocorrosion processes are a significant cause of occlusal abnormalities, and they can have harmful biological effects due to an increased release of metal ions and wear products. Moreover, abrasive wear products lead to decreased mechanical properties, particularly on the contact of a tribological pair.…”

Wear and Corrosion Interactions at the Titanium/Zirconia Interface: Dental Implant Application

“…These fluctuations may be the result of third‐body particles that have entered the system . The abrasion from the abutment material rubbing on the disc likely caused oxide layer detachment, surface deformation, and material shearing . Eventually the released wear particles become trapped in the contact zone.…”

“…No studies have evaluated the effect on implants and abutments from the combination of both electrochemical and frictional degradation. Tribocorrosion, an area of material science that examines the combined effects of both wear and corrosion, has evolved specifically to fill these gaps in the literature . Based on the tribological processes, tribocorrosion can be mainly classified as sliding‐corrosion (under large sliding motion), fretting corrosion (under micromotion), erosion‐corrosion (solution/surface interface), fatigue‐corrosion (under cyclic loading), or stress‐corrosion (under high stress due to impact or loading).…”
