INTRODUCTION
Gingival recession was treated with gum drop technique (GDT) along with pericardial membrane, advanced platelet rich fibrin (A-PRF) and injectable platelet rich fibrin (i-PRF) in the defect sites for regeneration of soft tissue.
PATIENT CONCERNS
Several 3-4 mm of recession sites in the maxillary right and left canine and premolar region. These sites were selected and divided into two groups: A and B based on the application with A-PRF and pericardium, respectively. Probing pocket depth (PPD), clinical attachment level (CAL), recession height (RH), recession width (RW) and keratinized tissue width (KTW) were assessed. The keratinized tissue width (KTW) was measured as the distance between the marginal gingiva and the mucogingival junction.
TREATMENT
The defects were treated with the GDT following irrigation with i-PRF and followed up for 6 months. Both groups achieved significant root coverage which was stable even after 6 months post operatively. Keratinized tissue showed a 1 mm gain with pericardial membrane.
引言
采用牙龈贴敷技术（GDT），并在缺损部位联合使用心包膜、高级富血小板纤维蛋白（A-PRF）和可注射富血小板纤维蛋白（i-PRF）来治疗牙龈退缩，以促进软组织再生。
患者情况
上颌左右尖牙及前磨牙区域有几处3 - 4毫米的牙龈退缩部位。根据分别应用A-PRF和心包膜的情况，将这些部位分为A组和B组。评估了探诊深度（PPD）、临床附着水平（CAL）、退缩高度（RH）、退缩宽度（RW）和角化组织宽度（KTW）。角化组织宽度（KTW）测量为边缘龈与膜龈联合之间的距离。
治疗
用i-PRF冲洗后采用GDT治疗缺损，并随访6个月。两组均实现了显著的牙根覆盖，术后6个月仍保持稳定。使用心包膜后角化组织增加了1毫米。
