Modeling of Dental Implant Osseointegration Progress by Three-Dimensional Finite Element Method

Applied Sciences, 2020
As osseointegration is a time-dependent process, biomechanical assessment is thought to determine whether a fibrous encapsulation or a bone covering will develop around an implant, according to the stress in the implant and surrounding bone.

Nanostructured Titanium Implant Surface Facilitating Osseointegration from Protein Adsorption to Osteogenesis: The Example of TiO2 NTAs

International Journal of Nanomedicine, 2022
Titanium implants have been widely applied in dentistry and orthopedics due to their biocompatibility and resistance to mechanical fatigue. TiO2 nanotube arrays (TiO2 NTAs) on titanium implant surfaces have exhibited excellent biocompatibility ...

Electrical stimulation to promote osseointegration of bone anchoring implants: a topical review

Journal of NeuroEngineering and Rehabilitation, 2022
Electrical stimulation has shown to be a promising approach for promoting osseointegration in bone anchoring implants, where osseointegration defines the biological bonding between the implant surface and bone tissue.

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 ...

Role of implants surface modification on osseointegration: A systematic review.

Journal of Biomedical Materials Research. Part A, 2020
Long-term and stable fixation of implants is one of the most important points for a successful orthopedic surgery in the field of endoprosthesis. Osseointegration, functional connection between bone and implants, is considered as a pivotal process of ...

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.

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.

3-D macro/microporous-nanofibrous bacterial cellulose scaffolds seeded with BMP-2 preconditioned mesenchymal stem cells exhibit remarkable potential for bone tissue engineering [PDF]

International Journal of Biological Macromolecules 2020, 2020
Bone repair using BMP-2 is a promising therapeutic approach in clinical practices, however, high dosages required to be effective pose issues of cost and safety. The present study explores the potential of low dose BMP-2 treatment via tissue engineering approach, which amalgamates 3-D macro/microporous-nanofibrous bacterial cellulose (mNBC) scaffolds ...
