Patient: A 26-year-old man with localized tooth wear and demand for aesthetic rehabilitation of the anterior teeth presented to our department. The patient reported excessive consumption of energy drinks. Furthermore, multiple trauma and tooth fractures have occurred in the past.
Discussion: In the present case, three-dimensional (3D)-printed restorations were used to restore the vertical dimensions according to the Dahl concept. An indirect build-up using noninvasive restorations has been demonstrated to be beneficial due to its pleasing aesthetic outcome and the advantage of the 3D printing process. Adhesive bonding was adapted from previous studies using direct composite materials. Thus far, whether, and to what extent, the color of these restorations changes remains unclear. Furthermore, the material wear should be evaluated in future studies.
Conclusions: Moreover, 3D-printed, noninvasive restorations made of a computer-aided design/computer-aided manufacturing hybrid material are suitable for the application of the Dahl concept. Aesthetic improvement in combination with minimally invasive pretreatment of the teeth and subsequent noninvasive restorations led to the rehabilitation of the vertical dimension of occlusion. After a follow-up period of two years, harmonious occlusal conditions were observed in the posterior region.
