Why do implants break up? The second reason is biomaterial and strength

 

 
We have a term in the dentistry called MOE, the elastic coefficient slightly higher (GP 113) in all 4 titanium (GP 103) and titanium alloys (grade 5).
MOE is high in carbon implants but its strength is low. In ceramic implants (AL2O3), the strength is high, but the MOE or type of implant forces in the parafunctional movement is not noted.
 
   
 
 
In this way, the hardness of the carbon is compatible with the surrounding bone, but its body can not withstand the physiological forces on the body. If the force is more than the bearing of carbon implants, microscopic cracks occur in the implant body, and then the surface of the implant is severely corroded And tissue inflammation occurs and the implant is defeated.
Dental implants should be removed; these events indicate that biomaterial stiffness and bone matter alone can not be sufficient for the clinical success of implant treatments. Ceramic implants are the opposite of the carbon implants, so that their compressive strength is high and hard. Biomaterials and bones have been sacrificed for this feature.
 
In addition, due to the ceramic brittleness and the possibility of failure due to tensile and shear forces, the geometric shape of the implant must be designed to withstand the force, due to limitation of the jaw, such as width and height. It is possible .
Very hard ceramic implants pass a lot of force into the bone and cause superficial bone ectrophy. In research, it has been concluded that the bone should tolerate more than 5 microspheres, along with the function (function) within the limits of the physiological force.
