牙槽骨流失原因係咩?仔細睇睇下邊內容la

牙槽骨流失原因係咩?仔細睇睇下邊內容la


好多患者都會驚訝自己嘅牙槽骨流失佐,骨頭唔係好堅硬嘅咩?點解會唔見佐。下邊我哋睇睇牙槽骨流失嘅原因la:



一、牙周病會造成骨量流失:



專家介紹,首要原因系牙周病。牙周病導致牙周軟組織抵抗力下降,使寄生於口腔嘅細菌大量繁殖,牙周組織形成牙菌斑和炎症感染發生,並逐漸蔓延到牙根、牙槽骨,產生牙齒松動乃至脫落,持續降低成骨細胞活性,最終導致牙槽骨萎縮、骨質流失。



所以,喺種植牙前,如果有牙周病嘅話,需要對牙周病進行治療,使牙周組織能夠長期形式良好嘅功能,營造一個良好嘅口腔環境。

牙槽骨流失嘅原因

二、活動假牙也會造成骨量流失



專家指出,活動假牙有體積比較大、異物感、影響發音、唔得充分恢復咀噍效率等不足之處,唔少患者骨量流失嚴重,長期戴活動假牙也系一個誘因。



1.活動假牙壓迫牙床,支撐假牙嘅系牙槽骨和牙齦肉,長期嘅咀噍壓力都由其承受,而且戴上假牙容易壓傷、刮傷牙槽骨,加速牙槽骨量流失。



2. 活動假牙清潔唔到位,引起口腔炎症,傷及口腔黐膜,造成口腔黐膜潰瘍,進一步導致牙床軟組織和牙槽骨硬組織嘅萎縮。



三、多種原因導致牙槽骨量不足



據了解,除佐上邊嘅原因,還有許多其他因素會導致牙槽骨骨量不足:



1.外傷導致頜骨受損,骨缺損較多、骨連續性較差等特點,缺損區骨組織塌陷、牙槽嵴形態缺損唔利於種植修復;

  

2. 掹牙處理不當,將牙骨帶走咗,創傷過大嘅牙槽骨更容易吸收、萎縮,進一步導致牙槽骨額外損失;

  

3. 長期缺牙致骨區萎縮,牙缺失後,冇及時修復,長期缺牙造成上頜竇空腔化致上頜骨後牙區萎縮,兩者都會導致頜骨骨量不足。
