人造牙基本位置与周围组织的适当关系非常重要。Weiberg主张义齿后牙的颊尖和窝应位于牙槽嵴顶,Hickey等人则主张人造牙应置于“中立区”或自然牙列的位置,并且“中立区”的支持者们认为“中立区”不但没有忽视杠杆作用,而且通过颊、唇和舌的协调作用平衡了不稳定的杠杆作用。本文作者通过对咀嚼效率、舒适程度和发音影响的分析,比较了“中立区”和“牙槽嵴顶”两种排牙方法修复的效果。本研究选择10名健康的无牙颌患者,缺牙时间2～5年,以往从没用过全口义齿,每个患者分别按传统法 The proper relationship between the artificial tooth base and the surrounding tissue is very important. Weiberg argued that the buccal cusps and fossa of the posterior teeth of the denture should be on the crest of the alveolar ridge, while Hickey et al. Argued that the artificial teeth should be placed in a “neutral zone” or natural dentition and proponents of “neutral zone” considered “neutral The district not only did not neglect the leverage but also balanced the unstable leverage through the coordination of the cheeks, lips and tongue. The authors compared the effects of two methods of rowing, ”neutral zone“ and ”alveolar crest", on the analysis of masticatory efficiency, comfort, and pronunciation. In this study, 10 healthy patients with edentulous jaws were selected. The time for missing teeth was 2 to 5 years. In the past, no denture had ever been used. According to the traditional method
