Comparison of osseointegration in piezoimplants versus cylindrical implants [PDF]

, 2019
BACKGROUND: Dental implants have been successful for the restoration of edentulous areas, but current techniques are inadequate in areas lacking sufficient bone volume. Piezoelectric surgery has shown encouraging effects on both osseous healing.

Graded Hydroxyapatite Triply Periodic Minimal Surface Structures for Bone Tissue Engineering Applications

Advanced Healthcare Materials, EarlyView.
This study investigates the role of triply periodic minimal structures in load bearing bone tissue engineering applications. Research uses a combination of mechanical testing, material characterization, and in vitro tests to study the impact of TPMS lattice structures (gyroid, lidinoid and split‐P).

TPMS‐Gyroid Scaffold‐Mediated Up‐Regulation of ITGB1 for Enhanced Cell Adhesion and Immune‐Modulatory Osteogenesis

Advanced Healthcare Materials, EarlyView.
A) SLM generates biomimetic bone scaffolds with consistent porosity but varying TPMS‐Gyroid unit cell designs (TG15, TG20, TG25, TG30). B) By enhancing the expression of ITGB1, TPMS‐Gyroid scaffolds can facilitate osteogenic differentiation in BMSCs and promote M2 polarization in macrophages.

De Novo Design of Integrin α5β1 Modulating Proteins to Enhance Biomaterial Properties

Advanced Materials, EarlyView.
NeoNectins are de novo‐designed miniproteins that selectively bind and stabilize the extended open form of integrin α5β1. When grafted onto biomaterials including hydrogel and titanium, they promote cell attachment and spreading in vitro and promoting tissue integration and bone growth in animal models, demonstrating broad potential for regenerative ...

Biomimetic Cell Membrane‐Coated Scaffolds for Enhanced Tissue Regeneration

Advanced Materials, EarlyView.
This review examines the development and use of cell membrane‐coated scaffolds in tissue engineering. Bioinspired phospholipid and glycocalyx coatings enhance anti‐fouling, anti‐thrombogenic, and selective molecular recognition properties. Native cell membrane coatings further support cell‐specific interactions, immune modulation, and reduced bacterial

Effect of Medications in Osseointegration

Journal of Multidisciplinary Dental Research, 2023
Implants have been a modern solution for treating edentulism nowadays. But the effect of certain diseases as well as medications marks a question among the dental practitioners about the survivability of implants. This article aims to discuss the effect of certain medications and its effect in osseointegration.

A Multifunctional Nanodelivery System Modified by Fusion Peptides Acts as Teriparatide Carrier for Noise‐Induced Hearing Loss Therapy

Advanced Science, EarlyView.
The fusion peptide LR27‐modified thermosensitive nanodelivery system exhibits both hair cell targeting and inner ear penetrating properties. This system sustainably and effectively delivers PTH1‐34 to the inner ear of a hearing loss mouse model via the synergistic effects of multiple peptides, achieving satisfactory hearing protection through ...
