Refabrication of a Removable Partial Prosthesis Using a 3D-Printed Record Base for a Patient With Microstomia

Microstomia, which is characterized by reduced oral opening, poses significant challenges in prosthesis fabrication, particularly during impression-taking. This technical report describes a novel workflow combining conventional techniques with digital technology to refabricate a removable partial denture for a 65-year-old man with microstomia. The process utilized 3D scan data of the patient's previous prosthesis to create a 3D-printed record base, eliminating the need for full-arch impressions and reducing the burden on both the patient and practitioner. The transparent printed base enabled precise adjustments, and conventional techniques were employed for clasp fabrication and functional seating impressions. This mixed workflow minimized dependency on advanced technical skills or specialized software, streamlining the process and achieving favorable clinical outcomes. The approach demonstrates the potential of integrating digital technology with traditional methods to address the unique challenges of prosthesis fabrication for patients with microstomia.
