Study on Tooth Wear of Spur Gears Under the Mixed Elastohydrodynamic Lubrication

Jixie chuandong, 2022
To study the wear evolution process and wear law of involute spur gears under the mixed elastohydrodynamic lubrication (EHL) and consider the lubrication conditions, thermal effects and load changes in the wear process of gear pairs, a wear model of gear

Is tooth wear in the primary dentition predictive of tooth wear in the permanent dentition? Report from a longitudinal study.

, 2010
To determine the prevalence of tooth wear in the permanent dentition of a sample of 12-year-old school children and establish whether an association exists between tooth wear recorded now and tooth wear recorded in their primary dentition at age five.A ...

A biomechanical optimized Zr58Cu25Al14Nb3 bulk metallic glass dental implant improves peri‐implant stress distribution and bone quality under physiological loading

BMEMat, EarlyView.
This study reports a novel Zr58Cu25Al14Nb3 bulk metallic glass that possesses high mechanical strength and low elastic modulus, which further promotes efficient mechanotransduction and significantly improves peri‐implant bone quality upon cyclic occlusal loading.

Subperiosteal circumferential connective tissue graft for vertical implant soft tissue augmentation

Clinical Advances in Periodontics, EarlyView.
Abstract Background Vertical implant soft tissue augmentation is indicated to optimize esthetic outcomes in cases of peri‐implant soft tissue deficiency or dehiscence, particularly when the peri‐implant mucosa is exposed during a full smile. This manuscript describes the use of a subperiosteal circumferential connective tissue graft (SC CTG) for ...

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1

Cytoskeleton, EarlyView.
ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...

The Development and Experimental Validation of a Real-Time Coupled Gear Wear Prediction Model Considering Initial Surface Topography, Dynamics, and Thermal Deformation

Machines
Errors affect the actual meshing process of gears, alter the actual wear pattern of the tooth profile, and may even impact the overall service life of machinery.

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Distribution of tooth wear among institutionalized residents (50-89 years old) in Baghdad city\ Iraq (Cross-sectional study)

Journal of Baghdad College of Dentistry, 2014
Background: Tooth wear is one of the most common problems in the older dentate population which results from the interaction of three processes (attrition, abrasion and erosion) and it affects all societies, different age groups, and all cultures.
