固定桥桥体与牙槽嵴的关系有两种:接触式和悬空式。一般认为悬空式桥体因与牙槽嵴分离,降低了固定桥的舒适性,患者难以接受,故临床上较少采用。作者在工作中将传统的悬空桥进行改良,并有选择地应用于临床,取得了良好效果。 1 临床资料 1.1 病例选择:14例中,男11例,女3例,平均年龄62岁,上颌第一磨牙5例,下颌第一磨牙9例;缺牙区牙槽嵴明显萎缩,呈低平或凹陷状,牙槽嵴顶到(牙合)平面距离平均10mm,其邻牙符合固定桥 Fixed bridge and alveolar ridge relationship in two ways: contact and vacant. Suspended bridge is generally believed to be separated from the alveolar ridge, reducing the comfort of the fixed bridge, the patient is difficult to accept, so less used clinically. The author in the work will be the traditional suspension bridge for improvement, and selectively applied to clinical, and achieved good results. 1 Clinical data 1.1 Case Selection: 14 cases, 11 males and 3 females, mean age 62 years, 5 cases of maxillary first molar, mandibular first molar 9 cases; alveolar ridge alveolar atrophy was significantly reduced Or depression, alveolar crest to (occlusal) plane distance from the average 10mm, its adjacent teeth meet the fixed bridge
