The goal of this study was to evaluate the ability of the modified apically repositioned flap (MARF) technique to increase keratinized tissue at the donor site and to analyze if this procedure would enhance the indication for and predictability of the laterally positioned flap (LPF) without any consequences to the donor area. Thirty isolated defects with recession and/or lack of attached gingiva were treated in 30 healthy patients. All donor areas adjacent to these defects lacked ideal gingival conditions both in height and width. The MARF technique was used to increase these areas 8 weeks before the LPF was performed. Clinical evaluation was done at the donor and receptor areas after 18 months. The results showed that the donor area increased from 2.78 to 5.01 mm at 8 weeks and remained at 3.28 mm after the use of the LPF. The marginal tissue recession and probing depth remained clinically unchanged. In the receptor area, the recession decreased from 1.86 to 0.57 mm, and the keratinized and attached tissue increased from 0.71 to 3.57 mm and from 0.05 to 2.49 mm, respectively. The use of the MARF technique to enhance keratinized tissue at the donor area proved to be an efficient and predicable technique that also augmented LPF use without any consequences to the donor site.
本研究的目的是评估改良根向复位瓣(MARF)技术增加供区角化组织的能力,并分析该手术是否会增强侧向移位瓣(LPF)的适应证和可预测性,同时对供区无任何影响。对30例健康患者的30个孤立性牙龈退缩和/或附着龈缺失的缺损进行了治疗。所有与这些缺损相邻的供区在高度和宽度上均缺乏理想的牙龈条件。在进行LPF手术前8周,采用MARF技术增加这些区域的组织量。18个月后对供区和受区进行临床评估。结果显示,8周时供区从2.78 mm增加到5.01 mm,使用LPF后仍保持在3.28 mm。边缘组织退缩和探诊深度在临床上保持不变。在受区,退缩从1.86 mm减少到0.57 mm,角化组织和附着组织分别从0.71 mm增加到3.57 mm和从0.05 mm增加到2.49 mm。事实证明,使用MARF技术增加供区角化组织是一种有效且可预测的技术,该技术还增加了LPF的应用,同时对供区无任何影响。
