The neutral zone is defined as the area where the forces of the tongue pressing outward are neutralized by the forces of the cheeks and lips pressing inward. In this study records of neutral zones of 30 edentulous patients were used to establish the relation between teeth arrangement according to neutral zone principles and teeth arrangement according to crest of ridge. These 30 patients were classified according to their ages, edentulous periods and denture experience. The results have shown that the lower molars were positioned a little bit closer to lingual with respect to crest of ridge; premolars were positioned either close to crest of ridge or they were coincided on it. In the anterior zone, the teeth were in accordance with known principles of positioned of anatomic landmarks.
中性区被定义为舌向外施加的力与颊部和唇部向内施加的力相互抵消的区域。在本研究中，使用30名无牙颌患者的中性区记录，以建立根据中性区原则进行的牙齿排列与根据牙槽嵴进行的牙齿排列之间的关系。这30名患者根据年龄、无牙期和义齿佩戴经验进行了分类。结果表明，下颌磨牙相对于牙槽嵴向舌侧稍微靠近；前磨牙要么靠近牙槽嵴，要么与之重合。在前牙区，牙齿符合解剖标志定位的已知原则。
