Since dental implants must withstand relatively large forces and moments in function, a better understanding of in vivo bone response to loading would aid implant design. The following topics are essential in this problem. (1) Theoretical models and experimental data are available for understanding implant loading as an aid to case planning. (2) At least for several months after surgery, bone healing in gaps between implant and bone as well as in pre-existing damaged bone will determine…

Load Transfer Along the Bone-Implant Interface and Its Effects on Bone Maintenance

A state of the art review of the computational models used in evaluating the biomechanics of dental implant systems is provided and shows that load transfer along the bone-implant interface is not well understood.

The basic science of peri-implant bone healing

It is imperative for orthopedic surgeons to have a basic understanding of the process of peri-implant bone healing, which involves the formation of a stable fibrin clot that is a depot for growth factors and allows for osteoconduction.

A Parametric Study on a Dental Implant Geometry Influence on Bone Remodelling through a Numerical Algorithm

In this work, for the first time, external bone remodelling was numerically predicted over time and may be a useful aid for clinicians to prevent possible implant failures and define an adequate implant prosthetic rehabilitation for each patient.

Micromotion Phenomena at the Implant Bone Interface: A Biomechanical and Histomorphometric Study

Bone quality seems to affect implant micromotion although the exact determinants remain unclear and few and inconsistent correlations were found between the parameters evaluated.

It is shown that peri-implant bone healing, which results in contact osteogenesis (bone growth on the implant surface), can be phenomenologically subdivided into three distinct phases that can be addressed experimentally.

Timing of loading and effect of micromotion on bone-dental implant interface: review of experimental literature.

Whether this no-load healing period is validated by the experimental literature is examined, which suggests that there is a critical threshold of micromotion above which fibrous encapsulation prevails over osseointegration, and suggestions are made for the earliest loading time that achieves osseointedegration.

Dental implant design--effect on bone remodeling.

Bone remodeling around three different endosseous dental implant designs placed in dog mandibles was studied using radiography during lengthy periods of function and by histology after animal sacrifice, indicating that some crestal bone loss occurred for both the threaded and partially porous-coated implants.

Finite element analysis of crestal bone loss around porous-coated dental implants.

An equivalent stress equal to 1.6 MPa was determined to be sufficient to avoid bone loss due to disuse atrophy in the canine mandibular premolar region and, therefore, possible long-term bone remodeling.

Mechanical and morphologic investigation of the tensile strength of a bone-hydroxyapatite interface.

This study measured the bone-HA interfacial tensile strength for highly polished (approximately 0.05 micron alumina) dense HA disks in rabbit tibiae and found mechanical interlocking could not be eliminated as a mode of tissue attachment and contribution toBone-HA bonding, even after implanting an extremely smooth HA surface.

Predictable crestal bone remodelling around two porous-coated titanium alloy dental implant designs. A radiographic study in dogs.

The results showed that bone remodelled to the machined surface-to-porous coat junction for type B implants and achieved a steady state by 12 weeks of function, whereas a longer time was required to achieve this state with type A implants.

Effect of surface topology on the osseointegration of implant materials in trabecular bone.

It is found that HA-coated implants showed superior osseointegration in terms of both push out failure load and surface coverage by bone measurements, and an excellent correlation was found between the average roughness of the implant surface and pushout failure load.

Microhardness and anisotropy of the vital osseous interface and endosseous implant supporting bone

The results are consistent with the high rate of remodeling seen adjacent to endosseous implants at 12 weeks after implantation, and the Knoop microhardness values were significantly lower for periosteal and endocortical calluses than for cortical bone.
