牙龈退缩根面覆盖治疗1例

目的 牙龈退缩常常导致根面敏感、菌斑控制不良和牙龈美学等问题,影响患者的口腔健康和颜面美观。本病例采用根面覆盖术治疗牙龈退缩,以改善患者牙齿敏感问题。诊治经过：手术采用冠向复位瓣联合结缔组织移植瓣双层技术治疗退缩类型（recession type,RT）为1类的牙龈退缩。结果 术后2周,受区龈缘略水肿;术后12个月复诊,龈缘位置趋于稳定,根面覆盖率达100%,角化龈宽度及临床附着水平增加。患者无牙齿敏感、系带牵拉和瘢痕形成等不适症状,牙龈美学效果良好。结论 冠向复位瓣联合结缔组织移植瓣双层技术治疗RT 1类牙龈退缩效果良好,不仅能够获得完全根面覆盖、牙龈美学效果良好,而且增加了术区角化牙龈的宽度和临床附着水平。

Root coverage for the treatment of gingival recession: A case report

Objective: Gingival recession often results in root sensitivity, plaque retention, and esthetic issues, which have an impact on patients’oral health and facial appearance. In this case, root coverage was used to treat gingival recession and reduce root sensitivity. Diagnosis and treatment: The coronally advanced flap in combination with a connective tissue graft was used to treat the (recession type,RT) 1 recession. Results: Two weeks after the operation, the gingival margin of the recipient area was slightly swollen. After 12 months of follow-up, the gingival margin position tended to be stable, the root coverage rate reached 100%, and the width and clinical attachment of keratinized gingival increased. The patient had no uncomfortable symptoms such as root sensitivity, frenulum traction and scarring. The aesthetic effect of gingival is good. Conclusions: Coronally advanced flap combined with connective tissue graft is effective in treating the RT 1 recession, which not only obtains complete root coverage with good aesthetic effect, but also increases the width of the keratinized gingiva and clinical attachment in the operation area.
