Tooth Wear and Tribological Investigations in Dentistry

Applied Bionics and Biomechanics, 2022
Dental or tooth wear is a physiological process in the life cycle of teeth. Loss of the occlusal surface may cause excessive tooth wear. Several factors may contribute to tooth wear with different intensities and duration in the oral cavity.

An Improved Modeling and Numerical Analysis Method for Tooth Surface Wear of Double-Arc Harmonic Gears. [PDF]

Materials (Basel), 2022
Tooth surface wear is one of the most common failure modes of harmonic gears, especially in space drive mechanisms. Due to difficulty accurately modeling its wear failure model and the complex mechanism, its dynamic behavior and wear mechanism have not ...

Tooth wear: A review [PDF]

, 2021
Tooth wear is the result of four processes: abrasion (wear produced by interaction between teeth and other materials), attrition (wear through tooth-tooth contact), abfraction and erosion (dissolution of hard tissue by acidic substances).

Unravelling the functional biomechanics of dental features and tooth wear [PDF]

, 2013
Most of the morphological features recognized in hominin teeth, particularly the topography of the occlusal surface, are generally interpreted as an evolutionary functional adaptation for mechanical food processing.

The evolutionary paradox of tooth wear: simply destruction or inevitable adaptation? [PDF]

, 2013
Over the last century, humans from industrialized societies have witnessed a radical increase in some dental diseases. A severe problem concerns the loss of dental materials (enamel and dentine) at the buccal cervical region of the tooth.

Running-in wear modeling of honed surface for combustion engine cylinder liners [PDF]

, 2013
The texture change during running-in alters the performance and efficiency of a tribo-mechanical system. During mass production of cylinder liners, a final finishing stage known as ‘‘plateau honing’’ is commonly added to reduce the running-in wear ...
