由于上颌智齿正常萌出的空间不足,埋伏病例较多。从解剖关系上看,上颌智齿的埋伏状态和拔除方法以及拔除时应注意的事项,与下颌智齿的情况有所不同。拔除上颌埋伏智齿时,视野狭小,不易操作。如果操作错误,就会把智齿推入上颌窦,难度较大。因此,有必要在术前充分弄清埋伏牙的状态,确定适当的拔牙计划,掌握操作要点,正确安全地进行手术。其拔除方法如下。1.保证术野:拔除上颌埋伏智齿,术野狭窄,让患者大张口,下颌肌肉就会突起,容易
Due to the lack of space for the normal eruption of maxillary wisdom teeth, more ambush cases. From the anatomical point of view, the maxillary wisdom teeth ambush state and removal methods and removal should pay attention to things, and the situation of the mandibular wisdom teeth are different. Removal of the maxillary ambush wisdom teeth, narrow field of vision, not easy to operate. If the operation is wrong, it will push the wisdom teeth into the maxillary sinus, more difficult. Therefore, it is necessary to fully understand the status of the ambush before surgery to determine the appropriate extraction program, grasp the main points of operation, the correct and safe operation. The removal method is as follows. 1. To ensure that surgery: removal of the maxillary ambush wisdom teeth, surgical field is narrow, so that patients with large mouth, jaw muscles will be prone, easy
