The Osseointegration of Magnesium Oxidized Implant
… surface is on the rise as a way to improve the osseointegration. The aim of this study is to compare the osseointegration between magnesium oxidized implant, TiUnite and machine-turned implant, to establish a better understanding of the effect of anodic oxidization on commercially pure titanium. …

On osseointegration in response to controlled surface nanotopography
… and biomechanical (removal torque) outcomes of osseointegration. The first study used a specially designed implant with nanopatterns only at the cylindrical part facing the bone marrow and not the threads that were engaging the cortical bone. Analyses showed that the gene expression of the …

Dreidimensionale Charakterisierung der Osseointegration von Titanimplantaten mittels Mikrocomputertomographie
… der Herausstellung von Unterschieden bei der Osseointegration modifizierter Titanimplantate mit beiden Methoden ähnliche Ergebnistrends gefunden werden. Eine Signifikanz (p < 0,01) der Unterschiede bei der Knochenneubildung konnte jedoch ausschließlich mit der mikrotomographischen Analyse …

Multi-scale structural design of titanium implants for improved osseointegration
Osseointegration success of bone-interfacing implants is reduced for many compromised patients, necessitating improved implant design. Though material and mechanical properties of titanium make it attractive for load-bearing dental and orthopaedic implants, limited advancements have been made to …

Die Osseointegration von Implantaten in Extraktionsalveolen in Abhängigkeit von der Wundversorgung
… noch nicht endgültig beantwortet worden. Wie die Osseointegration eines Implantats beeinflusst wird, wenn Knochenersatzmaterial oder Membrane zum Einsatz kommen, ist noch unklar. Die vorliegende histologische tierexperimentelle Studie untersucht die Osseointegration von Sofortimplantaten, die mit …

Osseointegration einer mit Plasma-Immersions-Ionen-Implantation behandelten Autokompressionsklammer aus Nitinol
Es wurde die Einheilung einer mit Plasma-Immersions-Ionen-Implantation beschichteten Autokompressionsklammer aus Nitinol im Seitenvergleich mit einer unbehandelten Klammer an sieben Beagle-Hunden überprüft. Aufgrund der Autokompressionsklammer war ein gleichzeitiger Vergleich der Heilung mit bzw. …

Mechanisms of Osseointegration: Experimental Studies on Early Cellular and Molecular Events in vivo
… implant, governing the early structural basis of osseointegration. The ultimate aim was to determine the strength of the early formed bone/implant interface, by measuring the removal torque forces, and thereby to correlate the results with the degree of inflammation, bone formation and bone …

Osseointegration of a Cementless Total Knee Arthroplasty in a Murine Model of Glucocorticoid Induced Osteoporosis
… as to how treatments might be used to improve osseointegration in the face of GC treatment. In the current studies, we used an established cementless murine knee arthroplasty model to better understand how GCs impact bone regeneration, osseointegration and biomechanical strength. The mouse …

Osseointegration potential for heat treated 3D Ti6Al4V scaffolds seeded with mysenchymal stem cells in vitro
… stem cells (MSCs) will improve the potential for osseointegration of the implants, as the existing bone may be more inclined to unite with developing bone than with the implant substrate. Titanium-6 Aluminium-4 Vanadium (Ti64) is one of the most commonly used implant materials. Heat treatment of …

Multifunctional hybrid sol-gel implant coatings on anodized titanium substrates to improve osseointegration and antimicrobial effectiveness
… microbial cell proliferation while promoting osseointegration have been sought out by clinicians. While recent developments in material science and cell biology have seen the development of such coatings, many proposed systems lack clinical translatability. For example, to reach the clinic, …

Silver Doped Hydroxyapatite Coating on Titanium Surfaces and its Effect on Early Bone Response and Osseointegration
… surfaces and bone cell responses that promote osseointegration and long-term stability. Hydroxyapatite (HA)-coated Titanium (Ti) implants have been widely used due to its effect on bone response. However, microbial infection is common. One material known to have anti-microbial properties is …

Development And Application Of Biomimetic Electrospun Nanofibers In Total Joint Replacement
<p>Failure of osseointegration (direct anchorage of an implant by bone formation at the bone-implant surface) and implant infection (such as that caused by Staphylococcus aureus, S. aureus) are the two main causes of implant failure and loosening. There is a critical need for orthopedic implants …

Processing-structure-property relationships of surface porous polymers for orthopaedic applications
… widespread use, it is often associated with poor osseointegration, which can lead to implant loosening and ultimately failure of the device. Many attempts have been explored to improve the osseointegration of PEEK but none have had widespread clinical success. In this dissertation, a novel surface …

Evaluation of Osseointegration Between Two Different Modalities of Hydroxyapatite Implant Surface Coatings: Plasma Sprayed HA Coated Implants and Electrophoresis Deposited Nano HA Coated Implants
… The objective of this study was to evaluate the osseointegration between plasma sprayed (PS) hydroxyapatite (HA) coated implants and electrophoresis deposited (EPD) nano hydroxyapatite coated implants in an animal model. The quantity of osseointegration was inferred by interfacial strength and …

On the Bone Tissue Response to Surface Chemistry Modifications of Titanium Implants
… of titanium implants play an important role in osseointegration. From 1990, a lot of engineering techniques have been applied to dental implant productions for improving their clinical performance by changing surface properties. In particular, surface chemistry modification enhanced the strength …
