Periodontally accelerated osteogenic orthodontics (PAOO) is a treatment for bone defects associated with a lack of bone graft stability, especially in coronal locations. This study aimed to compare a modified technique of membrane fixation that utilizes periosteal sutures (using a pouch design) with the traditional approach, which does not use membrane fixation.
Twenty-eight patients with a total of 168 teeth treated were divided into two groups: 1-A, in which patients were treated using the modified technique (with membrane fixation), and group 2-B, in which patients were treated using the traditional technique (without membrane fixation). The postoperative bone thickness was evaluated via radiographic examination.
Postoperative improvements in bone augmentation were detected in both groups. At 12 months, the values of the CHBT (measured from the midpoint of the coronal third to the labial cortical surface, 0.84 ± 0.33 mm) and the values of VBL (measured from the alveolar crest to the cemento-enamel junction, - 2.35 ± 0.80 mm)were significantly greater in the modified technique group than those in the traditional technique group (CHBT:0.12 ± 0.21 mm and VBL:-1.39 ± 0.99 mm; P = 0.00 and P = 0.01).
This study shows that compared to the traditional technique, the modified PAOO technique with membrane fixation using periosteal sutures provides improved graft stabilization, superior coronal augmentation and satisfactory vertical volume.
牙周加速成骨正畸（PAOO）是一种治疗与骨移植稳定性不足相关的骨缺损的方法，尤其是在冠状部位。本研究旨在比较一种改良的膜固定技术，该技术使用骨膜缝线（采用袋状设计）与不使用膜固定的传统方法。
将 28 名患者（共 168 颗牙）分为两组：1-A 组，患者采用改良技术（膜固定）治疗；2-B 组，患者采用传统技术（无膜固定）治疗。通过影像学检查评估术后骨厚度。
两组均检测到术后骨增量的改善。在 12 个月时，改良技术组的 CHBT（从冠状三分之一的中点到唇侧皮质表面测量，0.84±0.33mm）和 VBL（从牙槽嵴到牙釉质-牙骨质界测量，-2.35±0.80mm）值均显著大于传统技术组（CHBT：0.12±0.21mm 和 VBL：-1.39±0.99mm；P=0.00 和 P=0.01）。
与传统技术相比，改良的 PAOO 技术联合使用骨膜缝线的膜固定可提供更好的移植物稳定性、更优的冠向增量和令人满意的垂直体积。
