The patterns of occlusion and disocclusion can be considered critical to the longevity of the components of the stomatognathic system, including the dental implants. In natural teeth, periodontal ligament behaves very differently from what happens with the implant abutments, precisely the absence of this ligament way. By not exist the periodontal ligament bone-implant interface, the distribution of these tensions works more directly , while in the natural teeth, this tissue acts as a shock absorber system that improves the absorption of occlusal tensions. Thus, the stresses transmitted to the implant and its components for implants and for implant bone interface are totally different from those observed in natural teeth. It is noteworthy that if the occlusal tensions exceed the carrying capacity of the system, the job will fail due to overloading and poor distribution of mastigatory tensions.
