下颌总义齿修复比较复杂,牙槽萎缩越明显,义齿固位越困难。义齿修复的效果,有许多是取决于义齿承托区粘膜的状况和可让性。口腔矫形科医师必须熟悉无牙颌粘膜结构的特点,才能进行合理的设计,提高义齿修复效果。作者检查下颌总义齿承托区粘膜的厚度,研究粘膜厚度和颌骨萎缩程度的关系。检查下颌无牙的尸体90例,男性28例,女性62例。年龄54岁～60岁2例,61岁～70岁21例,71岁以上67例。用有刻度的探针测量下颌粘膜的厚
Mandibular total denture repair more complex, the more obvious alveolar contraction, denture retention more difficult. Many of the effects of denture repair depend on the condition and accessibility of the mucosa in the denture support. Dental orthopedists must be familiar with the characteristics of the edentulous jaw mucosa in order to conduct rational design and improve the denture repair effect. The authors examined the thickness of the mucosa in the supporting area of the mandibular total denture and studied the relationship between mucosal thickness and the degree of jaw atrophy. 90 cases of mandibular toothlessness were examined, 28 males and 62 females. Two patients were 54 years old to 60 years old, 21 cases were 61 years old to 70 years old, and 67 cases were older than 71 years old. Measure the thickness of the mandibular mucosa with a graduated probe
