Abrasion and erosion are two increasingly common indications for dental treatment. Thanks to modern digital technologies and new restorative materials, there are novel therapeutic approaches to restoring such losses of tooth structure in a virtually non-invasive manner. The case study in this article demonstrates one such innovative approach. The patient's severely abraded natural dentition was restored in a defect-driven, minimally invasive manner using high-performance composite materials in the posterior region, and the "sandwich technique" in the anterior region. The restorations were milled on an optimized milling machine with milling cycles adapted for the fabrication of precision-fit restorations with thin edges.
