隨著牙周炎發展到中重度,患者容易出現牙齦退縮,齦乳頭的缺陷,黑三角的形成,甚至牙齒移位。牙周炎非手術治療、手術治療,正畸治療都與牙齦乳頭缺陷及牙齦退縮相關[1-3]。因此中重度牙周炎患者的正畸治療不僅需要矯正錯矜畸形,還需要盡力恢復牙列健康,功能和美觀,尤其在前牙美學區,需要牙周、正畸、牙體牙髓及修復科醫生的合作診療。
本文介紹1例Ⅱ期C級牙周炎患者,經過牙周基礎治療及維護治療,前牙區牙周單純翻瓣術,以及正畸治療后,發現上前牙明顯的局部唇側牙齦退縮及齦乳頭缺陷。通過術前X線根尖片測量及診斷飾面分析設計,唇側根面覆蓋以及齦乳頭的軟組織增量重建手術以及牙冠復合樹脂貼面修復,術后2年觀察,獲得較理想的美學效果,鄰面牙周附著水平的明顯改善,并維持牙齦乳頭的長期穩定,現報道如下。
