Soft palatal augmentation prosthesis （Soft PAP） is a newly developed device which improves speech quality by providing an articulation point for patients with functional or morphological imperfection of their tongue. Soft PAP was made with a thermoplastic plate molded on a working cast whose palatal shape was modified using silicone putty material to make a flat surface on the palate. This article introduces fabrication procedures of three types of Soft PAP.
