To compare effectiveness of Autologous Particulate Dentin (APD) with Demineralized Freeze-Dried Bone Allograft (DFDBA) in ridge preservation, using radiographic and clinical parameters.
Thirty subjects with indication of mandibular posterior teeth extraction were randomly assigned to either test or control group. After atraumatic extraction, ridge preservation was performed using APD or DFDBA mixed with i-PRF in test and control groups respectively. Both groups had sockets sealed with A-PRF membrane. Clinical parameters (plaque, gingival and healing indices) and radiographic parameters (vertical ridge height, horizontal ridge width) were assessed at baseline and 6 months using CBCT. Statistical analysis was performed using an independent t-test to compare clinical and radiographic parameters between the groups.
Both groups had significant decreases in ridge dimensions over 6 months (p < 0.001). The test group showed less reduction in ridge dimensions than control group at 6 months (p < 0.001). Mean change in vertical height was not significant (1.37 ± 1.32, 1.7311 ± 0.563), but in horizontal ridge width (1.3120 ± 1.13, 1.8093 ± 1.16) was significantly different between test and control groups respectively. There was no statistical difference in clinical parameters between the groups at 6 months (p > 0.001).
APD grafts resulted in significant improvements in radiographic parameters, specifically in vertical ridge height and horizontal ridge width, compared to DFDBA group.
Autologous particulate dentin is a promising, versatile substitute for regenerative procedures. While more research on its long-term efficacy and application is needed, current evidence suggests it could significantly improve patient care and outcomes.
通过影像学和临床参数比较自体颗粒牙本质(APD)与脱矿冻干骨同种异体移植物(DFDBA)在牙槽嵴保存中的效果。
30 名下颌后牙拔除适应证的患者被随机分配到试验组或对照组。在微创拔牙后,试验组和对照组分别使用 APD 或 DFDBA 与 i-PRF 混合进行牙槽嵴保存,两组均使用 A-PRF 膜封闭窝洞。使用 CBCT 在基线和 6 个月时评估临床参数(菌斑、牙龈和愈合指数)和影像学参数(垂直牙槽嵴高度、水平牙槽嵴宽度)。使用独立 t 检验比较组间临床和影像学参数。
两组在 6 个月时牙槽嵴尺寸均显著减小(p<0.001)。试验组在 6 个月时牙槽嵴尺寸的减小小于对照组(p<0.001)。垂直高度的平均变化无统计学意义(1.37±1.32,1.7311±0.563),但水平牙槽嵴宽度的变化(1.3120±1.13,1.8093±1.16)在试验组和对照组之间存在显著差异。6 个月时两组临床参数无统计学差异(p>0.001)。
与 DFDBA 组相比,APD 移植物在影像学参数方面,特别是在垂直牙槽嵴高度和水平牙槽嵴宽度方面,有显著改善。
自体颗粒牙本质是一种有前途的、多功能的再生替代物。虽然需要更多关于其长期疗效和应用的研究,但现有证据表明,它可以显著改善患者的护理和结果。
