Description
この発明は、義歯（入れ歯・ブリッジ）を作る際に、正中線（顔面を左右対称にわける仮想線）を得る為の顔面の正中決定装置に関するものである。 The present invention relates to a facial midline determination device for obtaining a midline (virtual line that divides a face in left-right symmetry) when making a denture (dentures / bridge).
従来、正中線を得る時には、患者の脇に位置し、鼻尖、上唇小帯、上唇結節、下唇中央溝およびオトガイ隆起中央部などを参考に、それぞれを連結して直線を引くものである。 Conventionally, when obtaining a median line, it is located beside the patient and connected to each other with reference to the tip of the nose, upper lip band, upper lip nodule, lower lip central groove, central bulge and the like, and a straight line is drawn.
そのために、次のような問題点が生じていた。
（イ）見る位置や角度によって正中がずれて、正しい位置を決定する事が困難な場合が ある。
本発明は、以上の問題点を解決したものである。As a result, the following problems have arisen.
(B) The midline may shift depending on the viewing position and angle, and it may be difficult to determine the correct position.
The present invention solves the above problems.
先端がＹ字型の本体（１）の一端に刃部（２）を取り付けると共にもう一端に照準（３）を取り付ける。本発明は、以上の構成よりなる顔面の正中決定装置である。 The blade (2) is attached to one end of the Y-shaped main body (1) and the aim (3) is attached to the other end. The present invention is a face midline determination device having the above-described configuration.
したがって、顔面正中線を引く時には、目視で正中を得るのと異なり、一定の正確な顔面正中線を引く事ができるようになった。 Therefore, when the face midline is drawn, a certain accurate face midline can be drawn unlike the case where the midline is obtained visually.
以下、本発明を実施するための最良の形態について説明をする。
先端がＹ字型の本体（１）の上部の一端に、照準（３）をつける。その照準は透明の円盤であり、垂直に交わる直径を印記してある。その内の一本の直径は、本体（１）の延長線上の直線と正確に一致するものとする。本体（１）の下部の一端には刃部（２）をつける。刃部（２）の方向は、本体（１）及び本体（１）の延長線上にある照準（３）の直径の方向と正確に一致するものとする。
本発明は、以上のような構造である。
これを使用する時は、保持部（４）を持って、患者の正面に位置する。次に、照準（３）の中心を鼻尖に合わせると共に、本体（１）の延長線上にある照準（３）の直径を鼻中線に一致させる。次に、装置を真上から見て、本体（１）と刃部（２）が正確に重なる位置にて、咬合床の蝋堤に刃部（２）で圧を加えて顔面正中線を引くものである。Hereinafter, the best mode for carrying out the present invention will be described.
Aiming (3) is attached to one end of the upper part of the Y-shaped main body (1). Its aim is a transparent disk with the perpendicular diameters printed on it. One of the diameters exactly matches the straight line on the extension line of the main body (1). A blade part (2) is attached to one end of the lower part of the main body (1). The direction of the blade part (2) shall be exactly the same as the diameter direction of the main body (1) and the aim (3) on the extension line of the main body (1).
The present invention has the above structure.
When using this, it has a holding part (4) and is located in front of the patient. Next, the center of the aim (3) is aligned with the tip of the nose and the diameter of the aim (3) on the extension line of the main body (1) is matched with the midline of the nose. Next, when the apparatus is viewed from directly above, the face midline is drawn by applying pressure to the wax embankment of the occlusal floor with the blade (2) at a position where the main body (1) and the blade (2) exactly overlap. Is.
