BACKGROUND
The periosteum is a highly vascular connective tissue with immense regenerative potential. These qualities make it a suitable autogenous graft. A technique is described for using an autogenous periosteal pedicle graft (PPG) for the treatment of multiple gingival recession defects.
METHODS
Twenty teeth in six subjects with Miller Class I and II recessions ≥ 2 mm were treated using PPGs. In addition to the depth of the gingival recession defect, the probing depth and widths of keratinized and attached gingiva were recorded. The mean +/- SD was calculated for each of the clinical parameters. The paired t test was used to test the significance of the change.
RESULTS
At the end of 1 year, 90.95% of root coverage was attained with a significant increase in the widths of keratinized and attached gingiva (P = 0.0001); no change was observed in probing depths (P = 0.36).
CONCLUSION
The PPG technique can be successfully used for the treatment of multiple gingival recession defects.
背景
骨膜是一种具有巨大再生潜力的高度血管化结缔组织。这些特性使其成为一种合适的自体移植物。本文介绍了一种使用自体骨膜蒂移植物（PPG）治疗多个牙龈退缩缺陷的技术。
方法
对 6 名 Miller 分类 I 级和 II 级退缩≥2mm 的 20 颗牙齿进行 PPG 治疗。除了记录牙龈退缩缺陷的深度外，还记录了探诊深度和角化及附着龈的宽度。对每个临床参数计算平均值±标准差。采用配对 t 检验检验变化的显著性。
结果
在 1 年末，获得了 90.95%的根覆盖率，角化和附着龈的宽度显著增加（P=0.0001）；探诊深度无变化（P=0.36）。
结论
PPG 技术可成功用于治疗多个牙龈退缩缺陷。
