Influence of immediate dentures on oral motor skill and speech

An investigation was designed to test whether the precision of finely coordinated orofacial movements is influenced by the transition from natural to artificial dentition. The oral motor skill of 16 patients was tested before extraction and within 2 weeks of wearing immediate dentures. Speech recordings were employed to detect changes in voice quality and speech sound production. Results showed that the loss of natural teeth and the wearing of immediate dentures did not alter sensorimotor pathways significant to the precision of oral motor skills. It was also determined that physical characteristics of dentures are significant factors in the production of acceptable speech.
