小児に対して比較的簡便に適応できる顎機能検査装置 (ナソヘキサグラフ<SUP>(R)</SUP>) が, 近年臨床家の間で普及してきている。この装置の有効性を確認するために, 任意点の入力方法, 3次元座標系での測定誤差, 小児患者への臨床応用の適否を検討した。任意点の入力の際, ペンポインターをCCDカメラの正面に向けなければ座標の誤認をする恐れがあった。測定精度は, 3次元座標系で, それぞれ機器誤差が1%以下であった。また, 小児患者に臨床応用した結果, 十分に応用可能であることが示唆された。

A jaw function tracing device (Gnathohexagraph<SUP>®</SUP>) that can be adapted to comparatively easy has been coming into wide use recently. The way of inputting an option point, a measurement error by 3 dimension coordinate, the propriety of the clinical application to the child were examined. If penpointer was not turned in front of the CCD camera, the mistake of the coordinate was easily made in the case of the input of the option point. As for the measurement precision, a measuring error was less than 1% respectively by 3 dimension coordinate. And, it was shown by the clinical result applied fully as for pediatric dentistry as well.
