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.

Predicting cortical bone adaptation to axial loading in the mouse tibia [PDF]
Journal of the Royal Society Interface, 2015 The development of predictive mathematical models can contribute to a deeper understanding of the specific stages of bone mechanobiology and the process by which bone adapts to mechanical forces.

Biomechanical Evaluation of Bone Quality Effect on Stresses at Bone-Implant Interface: A Finite Element Study [PDF]
Journal of Applied and Computational Mechanics, 2021 The aim of this study is to evaluate the effect of the alveolar bone quality on von Mises stress at the bone-implant interface during occlusal loading. Four (3D) finite element models of fully osteointegrated 3-mm diameter × 11.5-mm length dental implant

Bone Reports, 2022 Bone biopsy is still the gold standard tool to evaluate either trabecular or cortical bone, though the quantitative computed tomography of the vertebrae (QCT), a non-invasive technique, could be useful to evaluate bone structure in patients with chronic ...

Growth and Age-Related Abnormalities in Cortical Structure and Fracture Risk [PDF]
Endocrinology and Metabolism, 2015 Vertebral fractures and trabecular bone loss have dominated thinking and research into the pathogenesis and the structural basis of bone fragility during the last 70 years.

Journal of Bone and Mineral Research, 2020 Immobilization as a result of long‐term bed rest can lead to gradual bone loss. Because of their distribution throughout the bone matrix and remarkable interconnectivity, osteocytes represent the major mechanosensors in bone and translate mechanical into

CBCT assessment of bone thickness in maxillary and mandibular teeth: an anatomic study [PDF]
Journal of Applied Oral Science, 2020 The site of the sinus tract depends on the rate of resistance against abscess exudate drainage, bone morphology, and distance from the root apex to the outer cortical bone. Objective To assess apical bone thickness in buccal and palatal/lingual aspects

Regional diversity in the murine cortical vascular network is revealed by synchrotron X-ray tomography and is amplified with age [PDF]
, 2018 Cortical bone is permeated by a system of pores, occupied by the blood supply and osteocytes. With ageing, bone mass reduction and disruption of the microstructure are associated with reduced vascular supply.

Indian Journal of Dental Research, 2020 Aim: Mandibular cortical index has proven to be inversely correlated to bone densitometry; however, trabecular bone pattern has not been widely studied. Thus, the main objectives of this study were: (1) to analyze the correlations between three different

Cortical bone maturation in mice requires SOCS3 suppression of gp130/STAT3 signalling in osteocytes
eLife, 2020 Bone strength is determined by its dense cortical shell, generated by unknown mechanisms. Here we use the Dmp1Cre:Socs3f/f mouse, with delayed cortical bone consolidation, to characterise cortical maturation and identify control signals.
