牙齒地包天其實就系前牙反合、近中錯合及下頜前突3個症狀都系上下牙弓近遠中關係異常。系臨床上比較常見嘅錯合畸形症狀,如果唔及時矯治,可能會妨礙面前後向嘅正常發育。咁牙齒地包天會遺傳嗎
牙齒地包天會遺傳嗎?
好多人都以為地包天系遺傳導致。事實上,地包天分為牙源型、功能型、骨源型三種,主要系由於一些不良嘅習慣導致嘅,因此後天因素多一些,先天性遺傳性嘅因素也有一些,如果家長有地包天抑或頜骨發育畸形嘅話,細路都可能有呢個問題。

而一些全身性疾病、呼吸道疾病如慢性扁桃體炎,腺樣體增大、腫大等,為了呼吸道通暢和減小壓迫刺激,脷體常向前伸並帶動下頜向前,也會形成地包天。

母親餵養方式不當,喺餵奶時,奶樽如拿得太高,孩子必須把下頜外伸才能飲到奶,久而久之,下頜就會較上頜更突出,形成地包天。

另外,讓寶寶養成經常吮手指、咬嘴唇、咬物、吐脷、下頜前伸等唔良習慣以及奶嘴使用時間過長等原因也會造成地包天。

以上就系「牙齒地包天會遺傳嗎?」嘅具體介紹,希望對大家有所幫助。
