Piezography, prosthetic space recorded by pronunciation, can be used as a reference for arrangement of artificial teeth and polishing surface of a denture. In this case, a 67 year old female patient was presented for new dentures. Old dentures had class II relationship and poor retention. For fabrication of stable dentures, using piezography and lingualized occlusion was planned. After taking impressions with conventional method, conventional denture bases with wax rim were fabricated. Then, additional mandibular denture base was fabricated for piezography. With fast setting silicon impression material, piezography was recorded by using six pronunciations, `si`, `so`, `me`, `te`, `de`, and `mu`. According to the piezographic space, mandibular artificial teeth were arranged and modified for lingualized occlusion. As a result, the patient was satisfied with new dentures functionally and esthetically.
