This retrospective study compared the outcomes of implants placed in alveolar ridge preservation (ARP) treated sites with those in spontaneously healed (SH) sites.
The study included patients presenting with one implant placed in an ARP-treated socket and one in an SH site. The primary outcome was the comparison of Marginal Bone Level Changes (MBLC). Statistical analysis was performed to identify factors influencing MBLC, including age, gender, smoking, parafunctional habits, and prosthetic emergence angle.
Of these, 28 patients (23 females, 82.1%) were included in this analysis. Sockets in the SH group were classified as type I, whereas type II sockets were more common in the ARP group. The SH group exhibited significantly higher MBLC than the ARP group (p = 0.032), with values, respectively, of 1.00 [0.25; 1.62] and 0.40 [0.00; 1.00] mm. Among all evaluated parameters, the performance of ARP was the only factor significantly affecting MBLC (β = -0.72, SE: 0.32, p = 0.026). Age, gender, smoking, parafunctional habits, and prosthetic emergence angle did not significantly affect MBLC.
The study shows the potential role of ARP in maintaining stable marginal bone levels around implants. In our sample, ARP significantly reduced MBLC compared with spontaneous healing, highlighting its possible impact in clinical practice for better peri-implant bone stability.
本回顾性研究比较了在牙槽嵴保存（ARP）治疗部位植入种植体与在自然愈合（SH）部位植入种植体的效果。
该研究纳入了在ARP治疗的牙槽窝和SH部位各植入一枚种植体的患者。主要观察指标是比较边缘骨水平变化（MBLC）。进行统计分析以确定影响MBLC的因素，包括年龄、性别、吸烟、副功能习惯和修复体龈缘角度。
其中，28例患者（23例女性，82.1%）纳入本分析。SH组的牙槽窝分类为I型，而II型牙槽窝在ARP组更为常见。SH组的MBLC显著高于ARP组（p = 0.032），数值分别为1.00 [0.25；1.62] 和0.40 [0.00；1.00] mm。在所有评估参数中，ARP的效果是唯一显著影响MBLC的因素（β = -0.72，标准误：0.32，p = 0.026）。年龄、性别、吸烟、副功能习惯和修复体龈缘角度对MBLC无显著影响。
该研究显示了ARP在维持种植体周围边缘骨水平稳定方面的潜在作用。在我们的样本中，与自然愈合相比，ARP显著降低了MBLC，突出了其在临床实践中对改善种植体周围骨稳定性的可能影响。
