biomechanical effects

The long-term success of implants is determined, in part, by the forces that must support them. Since the implants do not have a band around the gums, there is no sense of pressure when biting so the forces created are higher. To compensate for this, the location of the implants must be evenly distributed across the prostheses they support.[19] The concentrated forces can lead to fracture of the bridge, components of the implant, or loss of bone surrounding the implant.[20] The final location of the implants depends on biological factors such as bone type, vital structures, health and mechanical factors. Implants placed in thick, strong bone such as those in the front of the lower jaw and the back of the upper jaw have lower failure rates than implants placed in lower density bone. People who suffer from grinding their teeth negatively affect the durability of the implants and increase the possibility of their failure.[21]
