title: [Orthodontics and speech therapy].
abstract: The author recalls the suction and deglutition are indeed primary functions; mastication and spoken speech are rooted in them. One must also take time, forth dimension, into consideration. The postural state represents the starting point of the movement; one pronounces phonemes just as one holds one's tongue or swallows. Having so described the preparation of the first phase of the first sequence of the swallowing act, the author points out that the unfolding of the process then depends upon neurophysiological laws. Deglutition and phonetic articulation are making use of the same osteo-neuro-muscular effectors. The author is showing the close link there is between dysmorphosis and neuro-muscular dysfunction. In the second part the fact is emphasized that morphological modifications and changes in neuro-muscular behavior go hand in hand and complement each other. Hence the need for a closer collaboration between orthodontists and orthophonists, which may be very useful. The presentation of five case histories of children being in double treatment, e.g. with both the use of an appliance and neuro-muscular reeducation, upholds the argument.
