Maxillary complete denture fabrication using CAD-based digital tooth arrangement in a patient with wide arch: a case report

Maxillary complete denture fabrication using CAD-based digital tooth arrangement in a patient with wide arch: a case reportThis case report describes the use of CAD-based digital tooth arrangement to overcome the limitations of conventional methods in a patient with a maxillary arch wider than the average Korean morphology.In such wide arches, average-based tooth arrangement often restricts the ability to adjust the occlusal plane and cusp positions, thereby limiting functional and esthetic reproduction.In this case, virtual tooth arrangement and occlusal analysis were performed using CAD software, and a putty index was fabricated on a 3D-printed reference model to guide the final arrangement.The fabricated maxillary cast metal complete denture and mandibular distal extension removable partial denture successfully achieved bilateral balanced occlusion, and the patient reported high satisfaction in both functional and esthetic aspects.This case highlights the clinical utility of digital tooth arrangement in atypically wide arches and suggests that CAD-assisted workflows can enhance accuracy and reproducibility in clinical prosthodontics.(
