Article describes the restorative treatment of a patient who presented with severely eroded teeth. A focused defect-oriented approach characterized this case. Digital techniques paired with accurate planning and meticulous implementation ensured the minimally invasive restoration of the worn tooth structure. The problem of worn and eroded teeth is becoming more prevalent. The pathological loss of tooth substance can be produced by erosion (acid-related tooth damage), attrition (tooth-to-tooth wear) or abrasion (mechanical processes). In most cases a number of factors contribute to the clinical picture. Once the causes have been established, suitable therapeutic measures can be planned. In modern dentistry, the removal of considerable amounts of tooth structure for the preparation of a restoration is viewed very critically. A more appropriate solution is to find a minimally invasive or noninvasive way of restoring the teeth using adhesively bonded restorations. This type of approach is described on the basis of the following case study.
Pre-operative situation
When he consulted our practice, the patient complained about restricted chewing function and tooth hypersensitivity. In addition, he was dissatisfied with the appearance of his teeth. The dental examination revealed large carious lesions and various defective fillings. All the teeth showed severe signs of erosion (Fig. 1). Substantial loss of tooth structure was evident in the anterior teeth in particular. The analysis of the smile line revealed that the length-to-width ratio had been negatively affected. In the relaxed smiling position, the teeth were hardly visible. In addition, the discrepancy between the smile line and the midline was very pronounced. The patient showed considerable loss of occlusal vertical dimension (OVD). A functional disorder (e.g. craniomandibular dysfunction) was not diagnosed. The aim of the [...]
