Osseointegrated prostheses for rehabilitation following amputation : The pioneering Swedish model. [PDF]

, 2017
The direct attachment of osseointegrated (OI) prostheses to the skeleton avoids the inherent problems of socket suspension. It also provides physiological weight bearing, improved range of motion in the proximal joint, as well as osseoperceptive sensory ...

In vitro cytocompatibility and antibacterial studies on biodegradable Zn alloys supplemented by a critical assessment of direct contact cytotoxicity assay

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 111, Issue 2, Page 241-260, February 2023., 2023
Abstract In vitro cytotoxicity assessment is indispensable in developing new biodegradable implant materials. Zn, which demonstrates an ideal corrosion rate between Mg‐ and Fe‐based alloys, has been reported to have excellent in vivo biocompatibility.

Implantation of heat treatment Ti6al4v alloys in femoral bone of Wistar rats

Journal of Materials Science: Materials in Medicine, 2022
Two heat treatments were carried out at below (Ti6Al4V800) and above (Ti6Al4V1050) the beta-phase transformation temperature (T TRANSUS  = 980 °C), to study the effect of microstructural changes on osseointegration.

Ability of modal analysis to detect osseointegration of implants in transfemoral amputees : a physical model study [PDF]

, 2013
Owing to the successful use of non-invasive vibration analysis to monitor the progression of dental implant healing and stabilization, it is now being considered as a method to monitor femoral implants in transfemoral amputees.

Surface modifications to promote the osteoconductivity of ultra‐high‐molecular‐weight‐polyethylene fabrics for a novel biomimetic artificial disc prosthesis: An in vitro study

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 111, Issue 2, Page 442-452, February 2023., 2023
Abstract A novel biomimetic artificial intervertebral disc (bioAID) for the cervical spine was developed, containing a hydrogel core representing the nucleus pulposus, an UHMWPE fiber jacket as annulus fibrosis, and titanium endplates with pins for mechanical fixation.

Does vitamin D have an effect on osseointegration of dental implants? A systematic review

International Journal of Implant Dentistry, 2022
Purpose The aim of this study was to systematically review the available evidence to evaluate the efficacy of vitamin D supplementation or vitamin D depletion on the osseointegration of implants in animals and humans.

Numerical Analysis of an Osseointegration Model [PDF]

Mathematics, 2020
In this work, we study a bone remodeling model used to reproduce the phenomenon of osseointegration around endosseous implants. The biological problem is written in terms of the densities of platelets, osteogenic cells, and osteoblasts and the concentrations of two growth factors. Its variational formulation leads to a strongly coupled nonlinear system

Novel nano‐hydroxyapatite coating of additively manufactured three‐dimensional porous implants improves bone ingrowth and initial fixation

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 111, Issue 2, Page 453-462, February 2023., 2023
Abstract Electron beam melting (EBM) has been used to fabricate three‐dimensional (3D) porous Ti‐6Al‐4V surfaces for acetabular cups in total hip arthroplasty. However, there are radiographic concerns regarding poor implant fixation and bone ingrowth around electron beam melted (EBMed) 3D porous cups.

Effect of short implant crown-to-implant ratio on stress distribution in anisotropic bone with different osseointegration rates

BMC Oral Health, 2023
Objective This study aimed to provide evidence for the clinical application of single short implants by establishing an anisotropic, three-dimensional (3D) finite element mandible model and simulating the effect of crown-to-implant ratio (CIR) on ...

A modified Coulomb's law for the tangential debonding of osseointegrated implants [PDF]

Biomechanics and Modeling in Mechanobiology (2020): 1-18, 2019
Cementless implants are widely used in orthopedic and oral surgery. However, debonding-related failure still occurs at the bone-implant interface. It remains difficult to predict such implant failure since the underlying osseointegration phenomena are still poorly understood.
