目的 观察改良隧道技术结合上皮下结缔组织移植治疗多牙位牙龈退缩和牙齿敏感的临床效果。方法 采用改良隧道技术结合上皮下结缔组织移植治疗多牙位牙龈退缩1例。通过临床照片比较、临床检查和患者主观感受对比评估该手术方式的临床效果，同时结合文献复习，针对多牙位牙龈退缩的手术方式利弊展开讨论。结果 临床照片比较以及临床检测发现，采用该手术方式退缩区域几乎达到完全的根面覆盖，同时牙龈的颜色、质地与周围组织相匹配，达到了良好的美学效果。同时，患者的冷热敏感症状明显好转。结论 改良隧道技术结合上皮下结缔组织移植是一种安全、有效的治疗多牙位牙龈退缩的手术方法。
： Objective To evaluate the clinical effect of treatment of multiple gingival recession with coronally advanced modified tunnel technique combined with connective tissue graft. Methods A case of multiple gingival recession was treated with coronally advanced modified tunnel technique combined with connective tissue graft. The clinical effect of the surgical procedure was evaluated by comparing clinical images, clinical examinations, and subjective feeling of the patient. Advantages and disadvantages of different surgical methods for the treatment of multiple gingival recession were discussed according to reviewing literature. Results Comparison of clinical images and clinical examinations indicated that by adopting this surgical method, the root surface of recession area was almost completely covered, the color and texture of the gum matched surrounding tissue, and ideal appearance was achieved. At the same time, the hot and cold sensitive symptoms of the patient were also alleviated remarkably. Conclusion The coronally advanced modified tunnel technique combined with connective tissue graft is a safe and effective surgical method for the treatment of multiple gingival recession
