Guided bone regeneration using titanium mesh and xenogeneic graft alone: Histologic findings and 7‐year follow‐up

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Guided bone regeneration is a reliable technique for treating alveolar ridge deficiencies, especially in cases of severe maxillary atrophy. This case report describes the clinical management of a partially edentulous female patient presenting horizontal bone resorption in the anterior maxilla.

Tooth autotransplantation combined with bone augmentation for reconstruction of the esthetic zone: A case report

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Reconstruction of cleft‐associated defects in the anterior maxilla is complicated by deficient hard and soft tissues, scarring, and altered anatomy. This case report describes tooth autotransplantation with simultaneous autogenous bone augmentation for replacement of a congenitally absent maxillary lateral incisor. Methods A 20‐year‐

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

open access: yesDevelopmental 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.

Membrane lipid metabolism as a regulatory frontier in neural crest biology: Roles for sphingolipids, cholesterol, and lipid rafts

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Neural crest cells are multipotent, migratory stem‐like cells essential for vertebrate development that contribute broadly to many tissues including the craniofacial skeleton, peripheral nervous system, and pigment‐producing cells. Their development progresses through phases of induction, specification, delamination, migration, and ...

All‐in‐One Intelligent Hemostatic Sponge: Rapid Hemostasis for Non‐Compressive Wounds With Synergetic Enhanced Antibacterial Efficacy and Self‐Reporting Biodegradation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Clinicians often concurrently tackle critical challenges including emergency hemorrhage, secondary infection, and the elusive tracking of biodegradation of conventional hemostatic agents for complex wounds. Here, we report an intelligent hemostatic sponge (spCS@AIE) by incorporating aggregation‐induced emission (AIE) nanoparticles with short‐wave ...

Laser‐Textured Field‐Engineered Interface for Robust Dry‐Processed Cathodes in Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Laser‐patterned dry electrodes applied to current collectors could serve as a promising alternative to the limitations of conventional dry electrodes. Laser technology provides a fast and simple method to enhance the surface roughness of current collectors, improving the adhesion at the electrode–current collector interface.
