[Case of complete denture using piezography]

A 69-years-old edentulous male patient visited with a chief complaint of repeated fracture of a lower complete denture. A new denture was fabricated to improve the denture base rigidity and to modify the shape of the polished surface and position of the artificial teeth arrangement.

It seemed that the lower complete denture was broken repeatedly because the thickness in the central part was insubstantial there was not a reinforcement metal structure, and possibly the occlusal force was strong. By Piezography method, we attempted to assemble the components requisite to improve strength including reinforcement of the metal structure.

In this case, a lower complete denture was successfully produced with high rigidity that might not obstruct the denture stability, by applying Piezography.
