They are perfectly tolerated and therefore biocompatible. Colonisation kinetics As opposed to bio-inert ceramics alumina, zirconthey are bio-active and therefore have chemical exchanges with living tissues.

After implantation, the material is the site of extracellular dissolution and cell-mediated degradation. Biological fluids occupying the micropores are enriched in Ca, which finishes with the precipitation of apatite crystals similar to those in the neighbouring bone process of calcification and not ossification.

If the macropores are large enough, the process of osteoconduction may come into play, as well as subsequent Haversian bone remodelling. Implant resorption should not be too rapid to allow the macropores to be colonised by mesenchymal cells at different stages of differentiation, which enables bone to be laid down.

The clinical outcome therefore depends on colonisation and resorption kinetics, which are affected by the chemical and physico-chemical natures of the implant; these criteria must therefore be fully controlled.

Their applications are often associated with the use of osteosynthesis devices.Biological osteosynthesis.

Fracture nonunions represent important complications in orthopedic surgeries. Nonunion repairs or bone defects are surgically challenging. Our aim was to describe a nonunion case, which was repaired with rapid bone recovery.

An 8-month-old male mixed breed dog that has been previously operated was.

Here you’ll find a list of the ISO technical committees in the order in which they were created. The first, TC1, deals with screw threads and was created back in While, more recently, TC was created to standardize the circular economy. Clicking on the committee name will give you more.

Osteosynthesis is the reduction and internal fixation of a bone fracture with implantable devices that are usually made of metal. It is a surgical procedure with an open or per cutaneous approach to the fractured bone.

[Biological osteosynthesis]. [Article in German] Biological fracture fixation means: conservation of bone perfusion, protection of the soft tissue envelope and reduction of systemic stress by strengthening the host-defense mechanism.

For preoperative planning, the following points have to be considered: choice of fixation method, reduction.
