Speech & Prosthodontics

Speech is a dynamic process with which prosthodontists are involved. Should a denture patient manifest difficulty in speech, it is crucial to differentiate defects which are denture-related from those produced by other coexistent conditions. Seven dimensions basic to speech are discussed: (1) respiration, (2) phonation, (3) resonance, (4) speech articulation, (5) audition, (6) neurologic integration, and (7) emotional behavior. Clinical aspects of these factors as they relate to prosthodontics are described. For speech purposes, static, positional concepts of incisor relationships and denture contours should not be emphasized at the expense of dynamic considerations. Each patient's condition should be evaluated to assure that the denture can provide an optimal environment for the rapid, coordinated muscle movements requisite for acceptable speech. The ability to produce, manipulate and articulate with sound is called speech. The restoration of form and function of missing teeth and oral structures not only denotes esthetics and mastication, but also phonetics if applied correctly aid in fabrication of physiologically and functionally sound prosthesis.
