Bone Remodeling - Dental Implants

During functional movements such as chewing, forces on the prosthesis will
be transferred to the implants and this will result in stresses being generated within the
bone surrounding the implants. The bone-implant interface is of great significance to
osseointegration as the utilization of dental implants may alter the mechanical
environment of the mandible. Bone remodeling occurs in the first year of function in
response to occlusal forces and establishment of the normal dimensions of the periimplant
soft tissues. The type of bone remodeling taking place in the bone tissue
surrounding the implant will be governed by the variations in the internal stress state.
Stress shielding and bone resorption will occur when no load is being transferred to the
supporting tissues, while abnormally high stress concentration can lead to implant
failure. For these reasons, it is essential to consider the effect of bone remodeling on
the performance of dental implants and prostheses in order to improve its efficiency.
The bone remodeling process around dental implants has been simulated in a number
of studies using a variety of models. Mathematical algorithms such as nano-interactions
and mechanosensory mechanisms have been incorporated into numerical models to
describe bone formation and osseointegration of dental implants. Furthermore, strain
energy density algorithm has been adapted to illustrate bone remodeling induced by
implants and fixed partial dentures.
