The aim of this clinical trial was to assess the impact of autologous concentrated growth factor (CGF) as a socket-filling material and its ridge preservation properties following the lower third molar extraction.
A total of 60 sides of 30 participants who had completely symmetrical bilateral impacted lower third molars were enrolled. The primary outcome variables of the study were bone height and width, bone density, and socket surface area in the coronal section. Cone beam computed tomography images were obtained immediately after surgery and three months after surgery as a temporal measure. Follow-up data were compared to the baseline using paired and unpaired -tests.
CGF sites had higher values in height and width when compared to control sites (Buccal wall 32.9 ± 3.5 vs 29.4 ± 4.3 mm, Lingual wall 25.4 ± 3.5 vs 23.1 ± 4 mm, and Alveolar bone width 21.07 ± 1.55vs19.53 ± 1.90 mm, respectively). Bone density showed significantly higher values in CGF sites than in control sites (Coronal half 200 ± 127.3 vs -84.1 ± 121.3 and Apical half 406.5 ± 103 vs 64.2 ± 158.6, respectively). There was a significant difference between both sites in the reduction of the periodontal pockets.
CGF application following surgical extraction provides an easy, low-cost, and efficient option for alveolar ridge preservation. Thus, the use of CGF by dentists during dental extractions may be encouraged, particularly when alveolar ridge preservation is required.

本临床试验旨在评估自体浓缩生长因子(CGF)作为拔牙窝填充材料的效果及其在下颌第三磨牙拔除后对牙槽嵴保存的影响。
共纳入 30 名完全对称的双侧下颌阻生第三磨牙患者,每侧各 60 个。本研究的主要观察变量为冠部骨高度和宽度、骨密度和牙槽窝表面面积。术后即刻和术后 3 个月行锥形束 CT 检查作为时间测量。采用配对和非配对 t 检验对随访数据与基线数据进行比较。
与对照组相比,CGF 组颊侧骨壁高度和宽度更高(颊侧骨壁 32.9 ± 3.5 比 29.4 ± 4.3mm,舌侧骨壁 25.4 ± 3.5 比 23.1 ± 4mm,牙槽骨宽度 21.07 ± 1.55 比 19.53 ± 1.90mm)。CGF 组骨密度也显著高于对照组(冠部骨密度 200 ± 127.3 比-84.1 ± 121.3,根尖部骨密度 406.5 ± 103 比 64.2 ± 158.6)。两组牙周袋深度均有显著差异。
在手术拔牙后应用 CGF 是一种简便、经济、高效的牙槽嵴保存方法。因此,鼓励牙医在拔牙时使用 CGF,特别是在需要牙槽嵴保存时。
