目的: 総義歯の交叉咬合排列の欠点とされている発音機能障害について検討する.<BR>方法: 有歯顎群, 義歯群 (交叉咬合排列群, 正常排列群) について, 単音節 (62子音と5母音) による語音明瞭度検査を行い, 聞き誤った語音について検討した. 被験者別に誤聴率と語音別誤聴率, 各群別に平均誤聴率と平均語音別誤聴率を算出した. また, 各群別に平均語音別誤聴率が平均誤聴率よりも高かった検査語音を抽出し (抽出誤聴語音), 調音点別に分析を行った.<BR>結果: 1. 誤聴率. 1) 交叉咬合排列群, 正常排列群ともに各被験者の誤聴率に有意差を認めた. 2) 義歯群では, 誤聴率と義歯装着期間との間に有意な負の相関を認めた. 3) 有歯顎群, 交叉咬合排列群, 正常排列群の各群の平均誤聴率に有意差を認めなかった. 2. 調音点別の抽出誤聴語音. 1) 歯茎音と声門音において, 交叉咬合排列群のほうが正常排列群よりも平均語音別誤聴率の高かった語音数が多い傾向を示した. 2) 交叉咬合排列群において, 正常排列群に比べ, 歯音, 歯茎音および軟口蓋音は調音点が異なる語音へ誤聴され, 声門音は先行子音が欠落する傾向を示したが, 有意差はなかった.<BR>結論: 語音明瞭度検査結果については, 交叉咬合排列群と正常排列群との間に有意な差は認められなかったが, 義歯群では, 誤聴率と義歯装着期間との間に有意な負の相関を認めたことから, 発音機能障害が慣れにより解消される可能性が示唆された.

Purpose: This study investigated pronunciation disorders regarded as a disadvantage in cross-bite arrangement of complete dentures.<BR>Methods: An articulation test of pronouncing 67 single sounds (62 consonants and 5 vowels) was applied to a dentulous subject group, and a complete denture-wearer group subdivided into a cross-bite group, and a normal-bite group. The rate of mishearing and the rate of mishearing each sound in each subject, and the average mishearing rate and the average mishearing rate of each sound in each group, were calculated. The test sounds that demonstrated a higher-than-average mishearing rate were sorted out and evaluated according to the place of articulation.<BR>Results: 1. Rate of mishearing. 1) In both the cross-bite group and the normal-bite group, there were significant differences among subjects. 2) In the complete denture-wearer group, there was a significant negative correlation between the rate of mishearing and the duration of having used the present complete denture. 3) There was no significant difference among groups. 2. Sorted misheard sounds according to the place of articulation. 1) The number of sorted misheard sounds involving alveolars and glottals in the cross-bite group was greater than in the normal-bite group. 2) In the cross-bite group, dentals, alveolars, and velars tended to be misheard as sounds with a different place of articulation, and glottals tended to lack the preceding consonant. However, there was no significant difference in comparison with the normal-bite group.<BR>Conclusions: Articulation testing in pronunciation indicated that there was no significant difference between the cross-bite group and the normal-bite group, but there was a significant negative correlation between the rate of mishearing and the duration of having used the present complete denture in the complete denture-wearer group. Therefore, it was suggested that pronunciation disorders can be recovered by experience with a denture.
