Dental erosion is a modern society problem. Patients afflicted with this disease often report to treatment already at an advanced stage of erosion, when an impairment of chewing and speech function appear along with disturbed aesthetics. The loss of dental hard tissues due to erosion is a long-term process, therefore its therapy should be carried out in stages. The first rehabilitation phase is aimed at eliminating existing pain and adapting the stomatognathic system to the newly determined, correct, spatial position of the mandible against the jaw. For this purpose, rehabilitation appliances are used, i.e. occlusal splints, overdentures or adhesive reconstructions with a composite material. After complete adaptation of the stomatognathic system to the new occlusal scheme, one can be proceed to the next stage of treatment, involving the final reconstruction of the dentition. To illustrate the methods of treating dental erosion, a description of the therapeutic treatment of a selected patient affected by the condition is presented in this paper.
