邻牙阻力是下颌阻生第三磨牙拔除时第二磨牙对该牙的胆力。一般认为近中斜位阻生、低位垂直阻生、低位水平阻生,大多数都嵌阻在邻牙远中面的接触点以下或与邻牙远中根接触,因而存在邻牙阻力。临床上常用肉眼观察法、探针法来确准邻牙远中面和阻生牙近中冠的接触方式,估计有无邻牙阻力,选择劈冠法
Orthodontic resistance is mandibular impacted third molar removal of the second molars of the teeth of the guts. Generally believed that the middle and oblique incarceration, low vertical occlusion, low level of incontinence, most of embedded in the adjacent teeth below the contact point in the middle or adjacent to the tooth and the distal root contact, and thus the presence of adjacent teeth resistance. Commonly used in clinical observation with the naked eye, probe method to determine the proximity of the distal surface of the teeth and impacted teeth near the crown of contact, to assess the presence of adjacent teeth resistance, choose the split crown method
