The treatment of a completely toothless mandibular arch represents a big challenge in the field of dentistry, especially when bone resorption is important in the case of patients remained without oral rehabilitation for a long period. The realization of complete denture which meet the requirements of prosthetic stability retention and comfort is often difficult. Even in the era of dental implantology, piezographic technique (impression and registration) remains an excellent option to overcome prosthetic instability due to the inevitable narrowing of the prosthetic corridor. The use of the neutral zone by piezographic recording led to have a complete denture respecting the physiology of the para prosthetic organs and a better organization of the prosthetic teeth. The aim of this clinical report , was to present according to a didactic approach, the prosthetic steps to perform a complete denture rehabilitating a resorbed toothless mandibular arch, using the piezographic impression and recording techniques.
