一、拔除阻生智齿所带来的问题下颌智齿阻生很大部分是近中倾斜位阻生,由于萌出不全,容易发生冠周炎。有的临床工作者往往强调它有害的一面而轻率地将其拔除。然而,笔者看到临床上有些病例,阻生智齿已经拔除,而与之相邻的第二磨牙又有严重的破坏,如第二磨牙远中颈部或颈下龋,有的已不能作永久充填,有的虽勉强作了永久充填,但仍免不了发生继发龋而致牙体毁坏。有的第二磨牙远中齿槽骨已有严重吸收,由于阻生智齿的支撑,故并不很松动,一旦智齿拔除,就出现明显的松动而失去咀嚼功能。上述两种情况,最终往往是以拔除第二 First, the removal of impacted wisdom Wisdom teeth caused by impaction of most of the impacted wisdom teeth is near the tilt of obstruction, due to incomplete eruption, prone to pericoronitis.

Some of the second molars distal alveolar bone has been seriously absorbed, due to the impaction of wisdom teeth support, it is not very loose, once the removal of wisdom teeth, obvious loosening and loss of chewing function. The above two cases, the ultimate is often unplug the second
