To estimate the change in the alveolar ridge by means of a new alveolar ridge preservation (ARP) approach, using an anodized titanium foil (Tseal) associated with a bovine bone graft (BBG) by cone-beam computerized tomography.
Sixteen patients, each presenting one hopeless tooth, were selected and these teeth were carefully extracted. The alveolar socket was filled with BBG and the Tseal was trimmed and adapted to the bone crest. The primary outcome variable was the change in the alveolar dimension (AD) measurements between baseline (T1) and 6 months (T2) 1mm below the palatal bone.
Imaging assessment of AD demonstrated a decreased value in all subjects. The absolute rate and percentage of absorption between T1 and T2 time point showed statistically significant differences. The mean AD varied from 9.88 ± 2.04 mm (T1) to 8.85 ± 1.92 mm (T2). On average, this ARP procedure maintained 89.55% ± 6.11% of the distance of between the buccal and palatal wall. No differences were observed between the maxilla and mandible (p greater than 0.05).
The application of a bovine bone graft covered with Tseal resulted in clinically important horizontal preservation of the alveolar ridge at 6 months after extraction.
通过使用阳极氧化钛箔(Tseal)联合牛骨移植物(BBG)的新型牙槽嵴保存(ARP)方法,通过锥形束计算机断层扫描来评估牙槽嵴的变化。
选择了 16 名每位患者都有一颗无望保留的牙齿的患者,并小心地将这些牙齿拔出。牙槽窝中填充了 BBG,将 Tseal 修剪并贴合到牙槽嵴顶。主要结局变量是在基线(T1)和 6 个月(T2)时腭骨下方 1mm 处牙槽宽度(AD)测量值的变化。
AD 的影像学评估显示所有受试者的数值均降低。T1 和 T2 时间点之间的吸收绝对值和百分比均显示出统计学上的显著差异。AD 的平均值从 9.88±2.04mm(T1)变为 8.85±1.92mm(T2)。平均而言,该 ARP 程序维持了颊侧和腭侧壁之间距离的 89.55%±6.11%。在上颌骨和下颌骨之间未观察到差异(p>0.05)。
在拔牙后 6 个月,用 Tseal 覆盖的牛骨移植物的应用导致了牙槽嵴水平方向的明显保存。
