Each person's voice is unique. Voice quality is characterized by intelligibility of speech (correlation between voice pitch, volume, timbre and speech speed). Changes in the oral cavity due to tooth loss and resorption of processus alveolaris maxillae or processus alveolaris mandibulae can cause defects in the patient's voice and speech. When using incorrect or functionally low-quality dentures, other changes can be observed, such as skipping, replacing, distorting, adding sounds, as well as nasal speaking. Restrictions or changes in the normal movement of the jaws may interfere with the transmission of acoustic energy through the oral cavity, thereby affecting both the voice characteristics and capabilities, and the balance of the oral resonance. Phonetic adaptation of prosthetic patients depends on the choice and placement of artificial teeth, on the thickness, size and placement of the prosthetic base, optimal tongue space, individual adaptive ability, and the patient's ability to recognize the sound. This report presents the possibilities for maximum restoration of voice characteristics in effective collaboration between the dental team and specialists in otolaryngology and speech therapy.
