The mucogingival conditions associated with the recession defects at the mandibular anterior region, not only make plaque control difficult to be performed by the patient but also pose a problem in passively advancing the tissues at the recipient site. This surgical technique is used to treat multiple recession defects in the mandibular anterior region.
Twenty-five sites in 17 subjects (11 women and 6 men) underwent modified bridge flap and de-epithelized gingival unit graft (d-GUG) as a single-step treatment modality to cover the denuded root surface, as well as increase the width of keratinized gingiva in recession type 1 gingival recession defects in the mandibular anterior region.
Nearly 60% of sites in our study showed complete root coverage, with a mean root coverage percentage of 88.08%. Furthermore, keratinized tissue width, keratinized tissue thickness as well as vestibular depth showed statistically significant increases as compared to baseline levels.
Thus, the modified bridge flap technique using d-GUG within the limitations of our study design, showed promising results in terms of recession coverage as well as management of the difficult mucogingival conditions at the mandibular anterior region.
下颌前部区域与牙龈退缩缺损相关的黏膜牙龈状况,不仅使患者难以进行菌斑控制,而且在被动推进受区组织方面也存在问题。这种手术技术用于治疗下颌前部区域的多个牙龈退缩缺损。
17名受试者(11名女性和6名男性)的25个部位接受了改良桥形瓣和去上皮牙龈单位移植(d-GUG),作为一种单步治疗方式,以覆盖裸露的牙根表面,并增加下颌前部区域1型牙龈退缩缺损处角化牙龈的宽度。
在我们的研究中,近60%的部位实现了完全牙根覆盖,平均牙根覆盖百分比为88.08%。此外,与基线水平相比,角化组织宽度、角化组织厚度以及前庭深度均有统计学意义的增加。
因此,在我们的研究设计范围内使用d-GUG的改良桥形瓣技术,在牙龈退缩覆盖以及下颌前部区域困难的黏膜牙龈状况管理方面显示出了有前景的结果。
