Built-In Electric Fields Dramatically Induce Enhancement of Osseointegration

Rapid and effective osseointegration is a great challenge in clinical practice. Endogenous electronegative potentials spontaneously appear on bone defect sites and mediate healing. Thus, bone healing can potentially be stimulated using physiologically relevant electrical signals in implants. However, it is difficult to directly introduce physiologically relevant electric fields in bone tissue.

Increased vascularization promotes functional recovery in the transected spinal cord rats by implanted vascular endothelial growth factor-targeting collagen scaffold

Spinal cord injury (SCI) is global health concern. The effective strategies for SCI are relevant to the improvement on nerve regeneration microenvironment. Vascular endothelial growth factor (VEGF) is an important cytokine for inducing angiogenesis and accelerating nerve system function recovery from injury. We proposed that VEGF could improve nerve regeneration in SCI.

Comparison between mineralized cancellous bone allograft and an alloplast material for sinus augmentation: A split mouth histomorphometric study

Several grafting materials have been used in sinus augmentation procedures including autogenous bone, demineralized freeze-dried bone, hydroxyapatite, β-tricalcium phosphate, anorganic deproteinized bovine bone, and combination of these and others. Yet, the issue of the optimal graft material for sinus floor augmentation is controversial.

Comparison of contact radiographed and stained histological sections for osseointegration analysis of dental implants – an in vivo study

Histology is still regarded as the gold-standard to determine bone implant contact (BIC) as a parameter representing implant stability. As the further processing of cut slices for contact radiography (CR) to stained and polished histological sections is time consuming and error prone, our aim was to assess agreement between CR and Giemsa-Eosin (GE) stained sections with regard to dental implants.

Evaluation of Immediate Dental Implant Augmented with Biphasic Calcium Phosphate Coated by Polylactide - co-Glycolide Versus to Immediate Dental Implant Only

Numerous bone grafts have been studied for augmentation of the healing outcomes of dental implants. The aim of this study was designed to compare the clinical and radiographic evaluation between immediate dental implant augmented with biphasic calcium phosphate (BCP) coated with polylactide -co- glycolide (PLGA) and immediate dental implant alone.

The synergistic effect of type I collagen and hyaluronic acid on the biological properties of Col/HA-multilayer-modified titanium coatings: an in vitro and in vivo study

Type I collagen and hyaluronic acid are both the main components of bone extracellular matrix, and play important roles in regulating a cell's behavior. In this study, the synergistic effects of type I collagen (Col) and hyaluronic acid (HA) on the biological properties of Col/HA-multilayer-modified titanium coatings were investigated.
