乜情況下需要拔智齒-

Posted By vickong pun     July 8, 2021

智齒,學名第三大臼齒,俗稱智慧齒、立事牙、盡頭牙,系口腔最靠近喉嚨嘅牙齒,一般系於16歲或之後才生長出嚟。喺智齒生長方面,個體差異很大,有些人可能只長1到2顆,有些人終生唔長,呢都很正常。有嘅智齒甚至長到一半就不再生長,稱為智齒阻生。要唔要拔智齒,不可一概而論。  ——應該拔智齒嘅情況:  (1)智齒阻生,導致智齒冠周炎反復發作抑或繼發間隙感染、頜骨感染等情形。而牙列中冇智齒以外嘅其他牙齒缺失、大面積破壞、嚴重根尖病。  (2)智齒與鄰牙唔得形成良好嘅鄰接關系,導致有食物嵌塞或滯留(唔一定有自覺症狀),容易繼發鄰牙嘅齲壞、牙槽骨吸收等,而牙列中冇智齒以外嘅其他牙齒缺失、大面積破壞、嚴重根尖病變等情形時。  (3)對頜冇與智齒相對嘅咬合牙齒,因此該智齒冇咬合功能,而牙列中冇智齒以外嘅其他牙齒缺失、大面積破壞、嚴重根尖病
拔智齒  (4)智齒錯位經常咬頰,而牙列中冇智齒以外嘅其他牙齒缺失、大面積破壞、嚴重根尖病變等情形時。  (5)智齒發育畸形,形態很差,冇保留價值,也需要拔咗佢。畸形嘅智齒與前面嘅牙齒唔容易形成良好嘅接觸關系,因而容易導致前面牙齒嘅病變。  (6)牙列擠迫經過正畸矯正後,根據正畸醫師嘅要求,預防因智齒萌出導致牙列擠迫復發。
