Klinički i tribološki pogled na trošenje zubi

This paper is an overview on differently interpreting tooth wear, clinical appearance and etiopathogenic models. A process of tooth wear on the ultrastructural level of dental surfaces may be explained by tribological mechanisms, clinically classified as: attrition, abrasion, erosion and abfraction. There are some difficulties in clinical differentiation of certain processes of hard dental tissue wear due to multifactorial etiology and synergistic effects of different mechanisms of tooth wear together with synchronized action over a longer period of time. In order to predict further actions with regard to both existing and planned procedures used during the period of oral rehabilitation, it is important to detect the mechanism which caused the loss of dental tissue, which should ensure clinical success. U radu su prikazane različite interpretacije trošenja zubi, njihove kliničke manifestacije te etiopatogenetski modeli nastanka. Tribološki mehanizmi objašnjavaju proces trošenja zubnih površina na ultrastrukturnoj razini, a klinički se klasificiraju kao: atricija, abrazija, erozija i abfrakcija. Složena etiologija, te sinergistički učinci različitih mehanizama trošenja uz njihovo sinkrono djelovanje tijekom dužeg vrijema uvjetuju teško kliničko razlikovanje pojedinih procesa trošenja tvrdih zubnih tkiva. Za klinički uspjeh je važno pravovremeno dijagnosticirati mehanizam koji je prouzročio gubitak zubnoga tkiva radi predvidivosti daljnjih zbivanja obzirom na postojeće i planirane zahvate tijekom oralne rehabilitacije.
