[Incisor infraclusion and muscular behavior. Thumbsucking].
After defining incisor infraclusion, the author relates the cause to either anatomical muscular abnormalities or to abnormalities of function. He concludes that the second type can be easily improved when the cause is removed. He discusses the most common of these causes, thumb sucking, which can only disappear when the child reaches an age allowing him to overcome this habit. Any coercive, mechanical, physical or psychological treatment will only worsen or prolong this problem.
