不磨牙的貼面

貼面

很多朋友不理解貼面和烤瓷牙比有哪些優點,今天給大家細述一下。

關鍵點就是兩字:微創!當然貼面的技術要求和細節把握要比烤瓷冠複雜得多。圖一是貼面牙備后的照片,黑色是排齦線。圖二是烤瓷冠牙備后的照片。所謂眼見為實!姑娘們,在追求美的同時也要兼顧健康!

貼面的優點

1. 貼面的牙體磨除量小:牙體磨除僅局限於牙釉質,磨除量極少,甚至於可以不磨除牙體組織,保留了牙齒的正常切道,接觸區,形態,食物溢出方式以及患者口腔內現有的天然保健方式。

2. 有效保護牙髓健康:因為磨除的牙齒少,瓷貼面修復對牙髓的損傷很小,預備后牙齒的敏感度也很低,瓷貼面是保護牙髓最好的固定修復方式。

3. 強度高:牙齒瓷貼面需與牙釉質粘結在一起,一旦與強度最高的釉質粘結為一體后,就具有很強的抗拉和抗剪切力,瓷貼面的破裂比全瓷冠的破裂更少。

4. 利於牙周健康:牙齒瓷貼面邊緣密合度高,可進行嚴格的拋光,能夠保持很好的牙齦健康狀態,對牙齦的刺激非常小,有利於牙周組織的健康。
