Review on Tooth Flank Fracture Failure of Hardened Gears

open access: yesJixie chuandong, 2022
There is a new tooth failure mode for hardened gears called tooth flank fracture(TFF). ISO published a technical specification for calculating the load capacity of tooth flank failure in 2019.

Stiffness Modeling of Tooth Interior Fatigue and Tooth Flank Fracture and Their Fault Characteristics in Electromechanical Coupling Systems

open access: yesShock and Vibration
Tooth flank fracture (TFF) and tooth interior fatigue fracture (TIFF) usually occur on case-harden gears in electromechanical coupling systems, both starting from the core caused by metal fatigue. The cracks propagate rapidly compared with the total life

Naturally-occurring tooth wear, tooth fracture, and cranial injuries in large carnivores from Zambia. [PDF]

open access: yesPeerJ, 2021
Determining the incidence and causes of craniodental damage in wild carnivores is often constrained by limited access to specimens with associated ecological data, such as prey type and abundance. We assessed dental condition and cranial injuries in lion,

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

open access: yes, 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.

Pediatric mandibular fracture therapy: A case report [PDF]

open access: yesVojnosanitetski Pregled, 2020
Introduction. Frequency of pediatric mandibular fractures is relatively uncommon. Apart from rare exceptions, there is minimal invasive access in the treatment of those injuries in order to avoid the future developmental disorders. Case report.
