拔牙後為什麽要及時鑲牙


    



    拔牙後為什麽要及時鑲牙



    牙齒是重要的咀嚼和發音器官,缺失後會造成諸多不良影響,如使咀嚼功能減退;影響發音功能,影響美觀,妨礙正常的工作和社會交往;導致颞颌關節病變。牙齒在颌骨上排列成對稱的弓形牙列,彼此緊密鄰接。

    當其中任何一顆牙齒受力時,其他牙齒均可協助支持。因而不會歪斜傾倒。當牙列中的牙缺失時,就破壞了牙的鄰接關系,會導致鄰牙向缺隙側傾斜移位,缺牙間隙縮小,與缺牙相對的牙齒會不斷伸長,導致局部咬關系紊亂。因此,牙齒長期缺失不但造成鑲牙困難,而且易發生食物嵌塞和咬紊亂,進而導致余留牙的齲病和牙周病,甚至颞颌關系疾病。
