How to contact between the arcus dentalis mandibularis (ADM) and the tongue (T) during pronunciation of vowels (VP) in normal 50 subjects was investigated by using the lower jaw recording boards. The relative differences of the contact lines between ADM and T during VP weren't significantly recognized among individuals, in spite of the length of VP. However, close relation in position of the tongue to the mandibular teeth during VP exists in terms of their contact lines. The conditions for settlement of lingual bar or plate in the mandible, proposed so far, are not contradictory to the results of this study. The availability for the contact lines might be a useful index for clinical judgement of appropriate dentures.
