摘要
前牙美学区由于牙周炎、局部解剖因素、机械损伤或异常力等原因易出现牙龈退缩、牙齿移位形成的“黑三角”的现象,是目前口腔临床治疗的难点之一。血管化腭骨膜间结缔组织(VIP-CT)瓣是一种上腭前蒂结缔组织瓣,血供充足,可促进骨移植物成骨,改善邻间隙软组织缺损。本文报道了1例前牙区牙龈退缩伴牙齿移位、龈乳头缺失的病例,经过VIP-CT转瓣移植和骨增量手术后软硬组织状况显著改善,随后联合冠修复恢复邻面触点,最终有效重建了美学区龈乳头,获得了理想的美学结果。
The“black triangle”formed by gingival recession and tooth displacement in the aesthetic area of anterior teeth due to periodontitis,local anatomical factors,mechanical injury,or abnormal occlusal force is a difficulty in oral clinical treatment.The vascularized interpositional periopel connective tissue(VIP-CT)flap is a connective tissue flap from the palate that has sufficient blood supply.It can promote bone graft osteogenesis and improve soft tissue defects in the labial and adjacent spaces.In this paper,we report a case of gingival recession in the aesthetic area with tooth displacement and absence of gingival papillae.The soft and hard tissue status was significantly improved after VIP-CT rotary flap transplantation and bone graft augmentation.This approach was combined with crown repair to restore the adjacent contact.The gingival papillae in the aesthetic area were effectively reconstructed,obtaining ideal aesthetic results.
