Firstly, dental bridge on natural teeth is variation of dental bridge due to support they provide. Because of the fact that chewing power that is transmitted over dental construction of the bridge on the carries and jaw bones, due to that it is very important to have enough teeth girders that are positioned properly.
During the process of teeth grinding, as a result tooth is reshaped into cylindrical conical shape, which is paralleled to the other girders due to proper positioning of the bridge construction. However, if the intentioned carrier tooth is not usable due to damage or for instance has big filling, we need to compensate that teeth part with another fiber strengthened composite. Further when tooth root needs endodontic treatment we add composite build on (pin). Therefore proper distribution of chewing power is enabled trough complete root length.
