ObjectiveTo compare bone volume and height changes of two types of deproteinized bovine bone mineral (DBBM) for lateral window sinus floor elevation (LSFE) with simultaneous implant placement.Materials and MethodsThis retrospective cohort study involved 72 patients who underwent LSFE using low‐temperature sintered cancellous bone‐derived DBBM (C‐DBBM) or high‐temperature two‐step sintered epiphyseal‐derived DBBM (E‐DBBM). Cone‐beam computed tomography (CBCT) was acquired preoperatively, immediately postoperatively, 6 months and 1–4 years post‐surgery. Bone volume (BV), apical bone height (ABH), endo‐sinus bone gain (ESBG), and crestal bone level (CBL) were evaluated through three‐dimensional fitting and superimposition. Linear mixed models (LMM) were employed to analyze factors influencing the reduction of BV (ΔBV) and ESBG (ΔESBG).ResultsThe E‐DBBM group showed no significant change in BV 1–4 years post‐surgery, while the C‐DBBM group demonstrated a significant reduction (p = .006) with volume stability of 85.86%. Bone height in the E‐DBBM group increased at 6 months and subsequently decreased at 1–4 years (p = .003). In the C‐DBBM group, it decreased at 6 months (p = .014), then further decreased at 1–4 years (p = .001). ΔESBG was lower in the E‐DBBM group than the C‐DBBM group from immediate postoperative to 1–4 years (p = .009). LMM showed graft material type was the primary factor influencing ΔBV (p = .026) and ΔESBG (p = .003).ConclusionsWithin the limitations of this study, both types of DBBM could achieve favorable clinical outcomes. E‐DBBM demonstrated enhanced stability in maintaining bone volume and height.

使用两种脱蛋白牛骨矿物质进行侧窗窦底抬高的骨体积和身高变化:一项为期 1-4 年的回顾性队列研究



目的比较两种脱蛋白牛骨矿物质 (DBBM) 在侧窗窦底抬高 (LSFE) 同时植入种植体的情况下的骨体积和身高变化。材料和方法这项回顾性队列研究涉及 72 例使用低温烧结松质骨源性 DBBM (C-DBBM) 或高温两步烧结骨骺衍生 DBBM (E-DBBM) 接受 LSFE 的患者。锥形束计算机断层扫描 (CBCT) 在术前、术后即刻、术后 6 个月和 1-4 年采集。通过三维拟合和叠加评估骨体积 (BV) 、根尖骨高度 (ABH) 、窦内骨增益 (ESBG) 和牙槽嵴骨水平 (CBL)。采用线性混合模型 (LMM) 分析影响 BV (ΔBV) 和 ESBG (ΔESBG) 降低的因素。结果E-DBBM 组术后 1-4 年 BV 无显著变化,而 C-DBBM 组显著降低 (p = .006),体积稳定性为 85.86%。E-DBBM 组的骨高在 6 个月时增加,随后在 1-4 岁时下降 (p = .003)。在 C-DBBM 组中,它在 6 个月时下降 (p = .014),然后在 1-4 岁时进一步下降 (p = .001)。从术后即刻到 1-4 年,E-DBBM 组的 ΔESBG 低于 C-DBBM 组 (p = .009)。LMM 显示嫁接材料类型是影响 ΔBV (p = .026) 和 ΔESBG (p = .003) 的主要因素。结论在本研究的局限性内,两种类型的 DBBM 均能取得良好的临床结局。E-DBBM 在维持骨体积和高度方面表现出增强的稳定性。
