Timing of the functional problem approach


We have studied lip seal following Professor Mew’s suggestion. In consequence, though adult of poor lip seal was recognized exclusively among malocclusion, children’s poor lip seal was found not only malocclusion but also normal occlusion. This research was very impressive for us. After we performed clinical investigation, epidemiological survey, and longitudinal examination on children’s oral functional abnormality, based on these results, we considered and discussed the timing of approach on functional problem.
