以红蜡片代替钢直尺测定无牙患者的垂直距离,方法简单,效果满意,现介绍于下。测量方法:1.于患者颏前中线处的最突点用兰墨水作一兰点,设为N点。2.取一长10—15毫米、宽8—10毫米的红蜡片,最好选用熔点38°的常用蜡,将蜡片的一端轻轻接触鼻底,某一直角对准鼻小柱中点(此点设为M点),口唇处弯向颏部。3.引导患者保持息止颌位,在平齐N点的红蜡片用探针或雕刀等工具划出第一道印迹,设为A点,AM的高度即为患者息止颌位垂直距离。4.于蜡片A点 Red wax instead of steel ruler to determine the vertical distance of toothless patients, the method is simple, the effect is satisfactory, are introduced below. Measurement methods: 1. The most prominent point in the patient's midline before the geniogram with blue ink as a blue dot, set to N points. 2. Take a 10-15 mm long, 8-10 mm wide red wax, the best choice of melting point of 38 ° wax, one end of the wax gently touch the bottom of the nose, a right angle aligned columella Point (this point is set to M points), lips bent to the chin. 3. To guide the patient to maintain the rest of the jaw position, in the level of N points of the red wax with a probe or carved knife and other tools to draw the first blot, set to A point, AM height is the patient's jaw vertical distance. 4. A wax point
