Background/Objectives: The aim of this study was to show a standardized four-step technique that can offer individually personalized full-mouth therapy for each complex dental patient with erosive tooth wear resulting from bulimia nervosa, focusing on the individualized vertical dimension of occlusion (VDO), functional and aesthetic stability, and patient-reported outcomes, including dental symptoms, nutrition, self-perception, and quality of life. Methods: The following steps are proposed for structured full-mouth rehabilitation. Step 1: Intraoral diagnosis via a single computer-aided impression. Step 2: Determination of a new adequate vertical dimension of occlusion and soft tissue prediction. Step 3: Removable sample dentures—prototypes. Step 4: Non-prep/minimal-prep crowns as the long-term provisional/definitive treatment. Results: Nine adults (11% male) with dental erosion caused by bulimia nervosa (78%), gastro-esophageal reflux (11%), and soft drinks (11%) were part of this cohort. The novel digital workflow enabled restoration of an individualized vertical dimension of occlusion, stable occlusion, appropriate centric and eccentric contacts, biomimetic dental anatomy, harmonious tooth proportions, and optimized red–white aesthetics. Dental problems (hypersensitivity, dental pain), nutritional behavior, body perception, and quality of life improved after the full-mouth rehabilitation. Conclusions: The presented digital workflow offers a promising approach for full-mouth rehabilitation in patients with severe dental erosion, particularly associated with bulimia nervosa, enabling structured restoration planning and stepwise evaluation of the vertical dimension of occlusion and functional adaptation. Prospective studies with larger cohorts are needed to confirm long-term clinical outcomes and patient-reported benefits.
