牙周手術後組織是怎樣愈合的?

  牙周手術後組織是怎樣愈合的?牙周手術後組織的愈合,首先是病變的消除過程,術區發生炎 性反應,組織充血水腫,炎性細胞浸潤,分解壞死組織和防止術區 感染,然後是表淺組織的增收修複。
組織愈合方式主要有3種.

新附著:這是最理想的愈合方式.牙周手術後,在暴露于 牙周袋內的牙根表面上,形成一層牙骨質,同時也有新的牙槽骨形 成。
在牙骨質和牙槽骨新生時,牙周膜纖維一端埋入牙骨質內,另 一端埋在牙槽骨內,由此形成新的正常牙周支持組織.

(2)生長結合上皮:牙周手術後,上皮細胞很快由牙龈表面上 皮向創面爬行生長,最早達到牙根表面,使牙根表面被一層長而薄 的結合上皮所覆蓋.因此,牙根表面不可能有新的牙骨質形成,因 而也不可能有新附著形成。

(3)-般性修複:牙周治療後炎症消退,牙周袋變淺或消失,但 未形成新附著,牙周袋的底部仍位于原來的水平.
