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.

The patient who has severely absorbed residual ridges, treatments are challenging to satisfy many factors: support, retention, stability, etc. The neutral zone or monoplane occlusion with non-anatomical tooth would be helpful to get additional retention and stability. The monoplane occlusion has been used long time because it can eliminate horizontal forces and many other advantages. The lingualized occlusion was introduced to improve chewing efficiency and esthetics. But from a stability aspect, it seems controversy between monoplane occlusion and lingualized occlusion. This case report shows the results of the treat two flat residual ridge patients using functional impression; piezography, and made 2 other dentures with monoplane and lingualized occlusion that patient can select denture.

In an edentulous situation, the oral rehabilitation with complete denture is substantially different from treatment of natural teeth. The artificial teeth arrangement and occlusion are important factor for the stability of the denture. Bilateral balanced occlusion is that stability of the denture is attained when bilateral contacts exist throughout all excursion and static states of the denture during function and, artificial teeth are arrangement in neutral zone where the forces between the tongue and cheeks or lips are equal. This is how dentist make a favorable prognosis. Therefore, dentists are have to be a little more involved in the selection and arrangement of artificial teeth.
