Influence of tooth p roprioception on speech articulation.
Based on an analysis of the data obtained, the following conclusion can be made: 1. Time used to pronounce /S/ is increased for patients when their prostheses are not being worn. 2. There is a decrease in formant frequency when pronounciation of /S/ takes place without the prosthesis in place. 3. The amount of time span increase was less for overdenture group than for the complete denture group; the drop of formant frequency was not as greater as that of the complete denture group. 4. The precision of speech movement for the production /S/ is affected by the presence of tooth proprioception.
