Influences of organic component on mechanical property of cortical bone with different water content by nanoindentation

AIP Advances, 2018
The phenomenon that water in bone has important influences on mechanical properties of cortical bone has been known. However, the detail of the influence mechanism is not clear, especially in the component hierarchy.

Changes of cortical bone pores structure and their effects on mechanical properties in tail-suspended rats

Medicine in Novel Technology and Devices, 2022
Cortical bone is the main mechanical bearing structure of bone, and the mechanical properties of materials are not only related to bone mineral density, but also largely depend on its pores microstructure which affected by blood vessels.

Should we use cortical bone screws for cortical bone trajectory? [PDF]

Journal of Neurosurgery: Spine, 2015
OBJECT In 2009, Santoni et al. reported cortical bone trajectory (CBT) as a method of inserting pedicle screws to obtain more solid fixation, and proposed the use of cortical trajectory screws with a more closely placed thread (cortical screws) for CBT.

Effects of cortical bone thickness and trabecular bone density on primary stability of orthodontic mini-implants

Journal of Dental Sciences, 2019
Background/purpose: Mini-implant screws are now routinely used as anchorage devices in orthodontic treatments. This study used synthetic bone models to investigate how the primary stability of an orthodontic mini-implant (OMI) as measured by resonance ...

Investigation on the Differences in the Failure Processes of the Cortical Bone under Different Loading Conditions

Applied Bionics and Biomechanics, 2022
Cortical bone is a transversely isotropic material, and the mechanical properties may be related to the loading direction on the osteon. Therefore, analyzing the differences in the failure processes of cortical bone under different loading conditions is ...

A CBCT Evaluation of the Proximity of Mandibular Molar Roots and Lingual Cortical Bone in Various Vertical Facial Patterns and Factors Related to Root-Cortical Bone Contact

Applied Sciences, 2023
The objective of this study was to assess the proximity of the mandibular molar roots and the lingual cortical bone in patients with various vertical facial patterns and determine factors related to root-cortical bone contact. A total of 145 patients (84

Spina bifida-predisposing heterozygous mutations in Planar Cell Polarity genes and Zic2 reduce bone mass in young mice [PDF]

, 2018
Fractures are a common comorbidity in children with the neural tube defect (NTD) spina bifida. Mutations in the Wnt/planar cell polarity (PCP) pathway contribute to NTDs in humans and mice, but whether this pathway independently determines bone mass is ...

Osteocyte RANKL is required for cortical bone loss with age and is induced by senescence

JCI Insight, 2020
In aging mice, osteoclast number increases in cortical bone but declines in trabecular bone, suggesting that different mechanisms underlie age-associated bone loss in these 2 compartments.
