摘　　要：通过测量１０名上下无牙颌患者（双颌组）和１０名上颌无牙颌患者（单颌组）的齿槽弓和中立区堤弓的宽度，以及堤平面与堤长轴的夹角，深入研究中立区与齿槽嵴顶的关系。结果发现，单颌组尖牙及前磨牙区齿槽弓明显窄于双颌组；单颌组中立区较双颌组接近齿槽嵴顶；中立区位置与齿槽嵴顶在尖牙区差异较大，在磨牙区差异较小，在前磨牙区基本一致。该结果可为双颌和单颌总义齿排牙提供有益的借鉴。For further study of the relation of the neutral zone position to the alveolar ridge crest, the widths of the alveolar crest arch and the occlusal rim arch, and the angles between the plane of occlusal rim and the central axis of the occlusal rim were measured on ten edentulous patients in maxillary and mandibular arches(two arch group) and ten in only maxillary arch(one arch group)。 The results showed that the alveolar crest arches of the one arch group were obviously narrower in the canine and the premolar regions than in those of the two arch group; the neutral zone was closer to the crest of the alveolar ridge in the one arch group than in the two arch group; the discrepancies between the positions of the neutral zone and the crest of the alveolar ridge were significant in the canine regions, smaller in the posterior molar regions, and almost none in the premolar regions. The results may provide useful references for the arrangement of the artificial teeth in two arch and one arch complete dentures.
