Hanau的咬合定律及其五因素对口腔修复有重大贡献,他最初认为人造牙的咬合与九个因素有关,即水平髁突斜度,补偿曲线、前伸切导、定位平面、牙轴的颊舌向斜度、矢状髁道、矢状切导、牙齿排列和牙尖高度。以后他又归纳为五个因素:髁导,补偿曲线,牙尖高度,切导和定位平面。他用图表明正因素间的相互关系(图1),而受到称赞。可是也有人认为它繁锁。而且在图中髁导和切导可随意地增加和减少,这就可能产生混乱。如图的右下部代表以牙尖高度(五因素之一)为主发生改变则,引起其他 Hanau's occlusal law and its five major contributors to the restoration of the dentistry were primarily attributable to nine factors associated with the occlusion of artificial teeth: the horizontal condylar gradient, the compensatory curve, the anterior cut guide, the plane of positioning, the cheek of the tooth axis Tongue tilt, sagittal condyle, sagittal guide, tooth alignment and cusp height. He later summed up as five factors: condyle guide, compensation curve, cusp height, guide and positioning plane. He was praised for the interrelationship between chart positive factors (Figure 1). But others think it is cumbersome. And in the figure condyle guide and guide can be arbitrarily increased and decreased, which may cause confusion. As shown in the lower right part of the cusp height (one of five factors) is the main change, causing other
