Prosthetic Rehabilitation of Completely Edentulous Complex Cases: The Role of Piezography

Prosthetic rehabilitation of mandibular edentulism represents a major challenge for dentists, particularly when dealing with patients with advanced resorption of the alveolar ridge or tissue loss due to surgical interventions. These complex clinical situations frequently compromise the effectiveness of conventional prosthetic solutions, leading to limitations in stability, retention, and patient comfort. Piezography plays a crucial role in managing clinical cases with severely resorbed or atypical ridges through the design of customized, comfortable prostheses. In addition, phonetic piezography improves patients’ quality of life by restoring efficient masticatory function and clear phonation. This article explores the technique of phonetic piezography, a method based on recording tissues in motion during phonation. The patient is asked to repeat phonemes such as “sis”, “so”, “te”, “de”, “me”, and “pe”. Each phoneme is carefully articulated to record a specific area. Through the analysis of two clinical cases, this technique has demonstrated its effectiveness in creating precisely adapted mandibular prostheses, even in very difficult anatomical conditions. By precisely registering the areas of contact between the prosthesis and the tongue, cheeks and lip, this technique improves prosthesis stability, reduces mucosal irritation and ensures harmonious integration with the patient’s natural movements.
