Abstract
In recent years, digital technology has been reported to be useful in maxillofacial prosthetic treatment. However, there are still many challenges in the application of digital technology to denture fabrication, both chair-side and lab-side, and palatal augmentation prosthesis （PAP） fabrication is no exception. In this report, digital technology was used to fabricate a PAP and a cobalt-chrome based partial denture for a patient with a tongue defect. The denture was designed from 3D data of the oral cavity and the existing denture obtained by optical impression, and the palatal morphology of the PAP obtained by scanning the functional impression at the time of trial fitting was reflected in the completed prosthesis. The resin base parts were then fabricated by computer-assisted milling, allowing the denture to be fabricated on a 3D printed model. The denture fit was good and speech results were satisfactory. This report suggests that the application of digital technology may be beneficial in the fabrication of prosthetic devices for patients with tongue defects.
