Well‐Defined Nanostructures: Concept, Impact and Perspective

Small, EarlyView.
This perspective explores a connectivity‐driven framework for classifying well‐defined nanostructures (WDNSs) beyond traditional dimensionality‐based approaches. By highlighting discrete connections, serial connections, 2.5D connections, and 3D interpenetrations, it examines the structural and functional impacts of WDNSs across catalysis, energy, and ...

Extended Fixation for Paprosky Type III Acetabular Defects in Revision Total Hip Arthroplasty with a Minimum Follow‐Up of 2 Years

Orthopaedic Surgery, Volume 15, Issue 1, Page 205-213, January 2023., 2023
We proposed the concept of “iliac extended fixation,” and found that EIEF (extracavitary iliac extended fixation) and IIEF (intracavitary iliac extended fixation) with porous metal augments and cementless cups are effective in reconstructing severe superior acetabular bone defects, with promising short‐term clinical and radiographic outcome.

OSSEOINTEGRATION OF DENTAL IMPLANTS: A REVIEW

Romanian Journal of Medical and Dental Education, 2020
The osseointegration processes are based on post-implantation healing processes that are modeled by the activation by complex mechanisms of macrophages that leads to the differentiation of new osteoblasts on the implant surface.

Toward Novel Porous Boronized Ti6Al4V/FHA Composite Implants by Combined Microwave Sintering and Temporary Space Alloying

Small Structures, EarlyView.
A process for synthesizing novel porous boronized Ti6Al4V/fluorohydroxyapatite (FHA) composite implants is proposed by combining microwave sintering and temporary space alloying. The porous structure enhances microwave penetration, promoting in situ boronization within the composites. The resulting optimal composite exhibits ultralow compressive moduli,

Comparison of Long‐Term Outcomes between the n‐HA/PA66 Cage and the PEEK Cage Used in Transforaminal Lumbar Interbody Fusion for Lumbar Degenerative Disease: A Matched‐Pair Case Control Study

Orthopaedic Surgery, Volume 15, Issue 1, Page 152-161, January 2023., 2023
Both n‐HA/PA66 and PEEK cages can achieve satisfactory long‐term clinical and radiographic outcomes in TLIF, while the n‐HA/PA66 group showed significantly larger cage union ratios than the PEEK group. And n‐HA/PA66 cage is an ideal alternative material comparable to the PEEK cage in TLIF.

Histodynamics of calcium phosphate coating on the osseointegration of medical-grade polycaprolactone β-tricalcium phosphate scaffolds

Frontiers in Biomaterials Science
Bone formation on implant surfaces occurs via distance and contact osteogenesis, with osseointegration influenced by the implant’s surface topography and coating.

The Biomaterial and Blood Clot Complex: A Crucial Early Environment for Osteo‐Coagulo‐Immunomodulation and the Advancement of Bone Biomaterials

Small Structures, EarlyView.
Various properties of bone biomaterials can modulate components of the blood clot (including the fibrin network, red blood cells, platelets, and the complement system) in vivo implantation, leading to the formation of a biomaterial–blood clot complex (BBCC) significantly impacting subsequent osteoimmunomodulation.

A lasting antibacterial, pro‐angiogenic, and pro‐osteogenic zirconium‐based bulk metallic glass for dental implants

VIEW, EarlyView.
This study presented a novel amorphous alloy, Zr61Cu23Al12Ti2Ag2 (at.%) (Zr‐BMG), which offered superior mechanical properties, strong antibacterial effects, and improved osseointegration capabilities for dental implants, making it a favorable alternative to conventional Ti alloy.

Animal Models for Investigating Osseointegration: An Overview of Implant Research over the Last Three Decades

Journal of Functional Biomaterials
Dental implants and bone augmentation are among dentistry’s most prevalent surgical treatments; hence, many dental implant surfaces and bone grafts have been researched to improve bone response. Such new materials were radiologically, histologically, and
