Abstract:
Loss of tooth structures caused by dental erosion can compromise both function and esthetics, and extensive involvement often necessitates comprehensive restorative treatment. When utilizing a digital facebow transfer for prosthesis fabrication, the characteristics of each method must be carefully considered to choose the most appropriate technique an appropriate approach.This case report describes the prosthetic rehabilitation of a female patient with a history of bulimia nervosa. The patient presented with severely eroded dentition due to self-induced vomiting, resulting in impaired masticatory function and esthetics. For the restoration, three types of digital facebow transfer methods—standardized photography, facial scanning, and jaw motion tracking— were employed during the provisional phase to assess posterior function. Various provisional restorations with different lengths of incisal edge lengths and anterior guidance angles were tested to evaluate anterior function and esthetics. Definitive restorations were fabricated using monolithic zirconia crowns. This case report presents the successful recovery of esthetics and function through a digitally guided, full-mouth rehabilitation approach.
