什麼是牙周組織?

  

  什麼是牙周組織?牙周組織包括牙齦、牙周膜、牙槽骨3部分。
其主要功能是保護和支持牙齒,使其固位於牙槽窩內,承擔咀嚼力量。
牙齦:牙齦是附著在牙頸和牙槽突部分的黏膜組織,呈粉紅色,有光澤,質堅韌。
牙齦邊緣稱為齦緣,正常呈月牙形。
齦緣與牙頸之間的小溝稱齦溝,正常齦溝深1~2ml。
兩鄰牙之間的牙齦突起稱齦乳突。
牙周膜:牙周膜由緻密結締組織所構成。
多數纖維排列成束,纖維的一端埋於牙骨質內,另一端則埋於牙槽窩骨壁裏,使牙齒固位於牙槽窩內。
牙槽骨:牙槽骨是頜骨包繞牙根的部分,藉牙周膜與牙根緊密相連。
牙根所在的骨窩稱牙槽窩。
牙槽骨和牙周膜都有支持和固定牙齒的作用。
