點解有D人種牙要植骨?

點解有D人種牙要植骨?
臨床上,部分患者喺種牙時,牙醫通過CT片檢查後告知需要植骨,植骨系乜?點解種牙前要植骨



簡單嚟講就像種樹需要土壤一樣,種牙都系需要足夠健康嘅骨組織。造成牙缺失嘅原因有很多,一般包括牙外傷、牙周病、根尖周病等,喺牙缺失嘅同時伴有需種植區域嘅牙槽骨吸收,缺牙後缺乏功能性刺激,骨組織進一步萎縮,導致骨量不足,無法完成種植,呢時便需要植骨。

乜系植骨?



植骨系通過植入人工骨粉嚟補足種植牙植入條件嘅一種常用方法,人工骨粉嘅優點系無需損傷自體取骨,而且骨吸收嘅速度很慢。一般植入嘅量很少,都系以克嚟計算嘅,植入前會嚴格測量牙槽骨骨量嘅密度、高度等,做到精確。



點解有D人需要植骨,而有D人就唔使?



呢個取決於牙槽骨條件。缺牙多年冇做過任何處理,或本身有嚴重嘅牙周病,呢D情況都容易導致牙槽骨萎縮,不足以支撐種牙嘅成長需要。此類情況下,就需要植骨嚟支撐。



植骨手術和普通種植手術嘅區咪,其實就系多啲操作時間,常規種植牙時缺損只需要簡單嘅植入一些人工骨粉即可,所以並冇增加患者嘅痛苦,就算系喺做上頜竇提升時,局麻下植骨患者也系基本感覺唔到痛苦嘅。



以上就系「點解有D人種牙要植骨?」嘅具體介紹,希望對大家有所幫助。
