Sažetak

The changes of tissue caused by occlusive trauma are primarily limited to the supporting structures of the tooth and may be also found on dentine. These lesions are not inflammatory but dystrophic and destructive. The histological findings most frequently show compression of blood vessels, stasis, trombosis, hemorrhage and necrosis. The supporting apparatus of the teeth is capable of adapting to strong and unusual forces during a certain period of time. If the excessive forces are rather frequently repeated they w ill unevitably lead to harmful consequences. It is very d ifficu lt to determine when parodontium becomes intolerant of an increased activity of a force. The force must reach a certain lim it to become pathological. The most important factor is the size of the force, while its frequency, direction and duration as well as reparative individual capacity are also relevant. Occlusive trauma can induce lesions manifested by resorption, root fracture and rupture of tooth cement. They are sometimes visible on roentgenograms which can be therefore used as a valuable diagnostic finding of occlusive traumatism. The paper presents typical examples of occlusive trauma with fractures and tooth root resorption as consequences. The ruptures of cement are rarely visible on roentgenograms. The teeth which have suffered occlusive trauma are frequent histological findings.
