Exploring the Role of Exosomes in Accelerating Orthodontic Tooth Movement

open access: yesJournal of Pharmacy and Bioallied Sciences
Background: Alveolar bone remodeling is a complicated biological process that is involved in orthodontic tooth movement (OTM). Recent studies have shown how exosomes, which are cell-secreted nanovesicles, influence cellular communication and encourage ...

A Double Case: Socket Shield and Pontic Shield Techniques on Aesthetic Zone

open access: yesCase Reports in Dentistry, 2020
When a tooth is extracted, a bone remodeling of the alveolar process occurs irretrievably. Various techniques have emerged over time to maintain the thickness of the bone crest in fixed prosthetics on teeth and implants.

Mn/Zn Bimetallic MOF‐Integrated Hydrogel Alleviates Excessive Mitochondrial Fission in BMSCs to Promote Osteoporotic Jawbone Repair

open access: yesAdvanced Science, EarlyView.
Excessive reactive oxygen species (ROS) and chronic inflammation impair bone marrow‐derived mesenchymal stem cells (BMSCs), contributing to poor healing in osteoporotic jawbone defect. The gelatin methacryloyl hydrogel loaded with manganese‐doped zeolitic imidazolate framework (Mn‐ZIF‐8@GelMA) promotes regeneration through redox regulation and ...

Long‐Term Expandable Periosteal Organoids Reconstruct a Functional Regenerative Niche That Support Hematopoietic Stem Cell Maintenance and Bone Repair

open access: yesAdvanced Science, EarlyView.
A robust periosteal organoid system enables long‐term expansion while preserving native cellular heterogeneity. These organoids recapitulate functional niche environments, support hematopoietic stem cell maintenance, and attenuate aging‐associated decline ex vivo.

Expression of sclerostin in alveolar bone remodeling of ovariectomized rats

open access: yes口腔疾病防治, 2020
Objective To investigate the expression and distribution of sclerostin in the alveolar bone of rat in the absence of estrogen, and to provide evidence for the analysis of the histological correlation between sclerostin and alveolar bone remodeling in rats. Methods The experimental subjects of this study were 32 8-week-old female Wistar rats. Among them,

PIAS3 CircRNA‐Loaded Lipid Nanoparticles Restore ALOX15 SUMOylation to Suppress Cementoblast Ferroptosis and Attenuate Orthodontically Induced Root Resorption

open access: yesAdvanced Science, EarlyView.
Orthodontic compression suppresses PIAS3 expression in cementoblasts, impairing ALOX15 SUMOylation and ubiquitin‐mediated degradation, which leads to ALOX15 accumulation, lipid peroxidation, ferroptosis, and osteoclastogenesis. Local delivery of PIAS3 circRNA‐loaded lipid nanoparticles restores the PIAS3–ALOX15 regulatory pathway, alleviates ...

Rational Surface Engineering Reduces Advanced Glycation End‐Product Adsorption and Improves Implant Integration

open access: yesAdvanced Science, EarlyView.
Targeted surface chemical modification prevents the accumulation of advanced glycation end products (AGEs) on implant surfaces, attenuates inflammation and fibrosis, effectively restores angiogenic activity, and improves osseointegration under diabetic conditions.

Reln mRNA Delivery Drives Neurogenic Bone Regeneration by Orchestrating Schwann Cell‐Mediated Exosomal Trafficking

open access: yesAdvanced Science, EarlyView.
MSNs serve as a robust vehicle for CRISPRa‐mediated Reln induction, driving bone repair through the establishment of a neurogenic‐supportive microenvironment. ABSTRACT Neurogenic bone regeneration is essential for the effective restoration of bone tissue functionality, while the mechanisms and new strategies underlying neurogenic bone regeneration ...

Force-induced increased osteogenesis enables accelerated orthodontic tooth movement in ovariectomized rats

open access: yesScientific Reports, 2017
As the number of elderly orthodontic patients increases, the impact of postmenopausal osteoporosis on orthodontic tooth movement (OTM) has attracted a great deal of attention because OTM relies on alveolar bone remodeling.
