Abstract:
Capturing impressions for maxillary defect patients with trismus is challenging due to limited mouth opening and defect complexity. This study introduces an innovative digital technique that highlights virtual reconstruction through the integration of intraoral scanning and a mirroring approach. Using the intact maxillary arch as a reference, the defect area is digitally reconstructed to design a provisional obturator with a streamlined workflow. By eliminating the need for extensive laboratory procedures, this method significantly enhances the efficiency of prosthetic fabrication and simplifies the overall impression-taking process.
