Abstract

Objectives

To investigate the radiographic changes of two different particle sizes of deproteinized bovine bone mineral (DBBM) following lateral sinus floor elevation (LSFE) with simultaneous implant placement.

Materials and Methods

A total of 104 patients with 128 implants receiving LSFE with simultaneous implant placement were included and divided according to the grafted DBBM: 47 using small particle sizes (0.25–1 mm), 57 using large particle sizes (1–2 mm). Cone beam computed tomography (CBCT) images were taken at three points (T0: before surgery, T1: immediate postoperative, T2: 6-month postoperative). The two-dimensional and three-dimensional augmentation parameters, including apical bone height (ABH), endo-sinus bone gain (ESBG), peri-implant bone height (PBH), marginal bone loss (MBL), and augmented bone volume (AV) were measured. The differences in augmentation parameters between the small and large particle sizes of DBBM were compared.

Results

AV was 916.76 (657.88–1243.74) mm³ at T1 and decreased to 823.73 (583.12–1178.79) mm³ at T2, pointing to a relative volume stability of 89.8%. Although ABH did not significantly differ between the two groups at T1 (p = 0.379) and T2 (p = 0.264), AV, ESBG, and PBH were significantly higher in the large particle group. At the 6-month follow-up, the reduction rates in AV (p < 0.001), ESBG (p = 0.022), and PBH (p = 0.004) were lower in the large particle group.

Conclusions

The augmentation outcome decreased after LSFE with simultaneous implant placement at the 6-month follow-up. Using the large particle size of DBBM improved the augmentation stability.

两种不同大小的脱蛋白牛骨矿物颗粒在侧窦底抬高同时植入的比较：影像学研究

目的探讨两种不同粒径脱蛋白牛骨矿物质（DBBM）在侧窦底抬高（LSFE）后的影像学变化。材料与方法共纳入104例128颗种植体同时植入LSFE的患者，并根据种植的DBBM进行分组：小颗粒（0.25-1 mm） 47例，大颗粒（1-2 mm） 57例。锥形束计算机断层扫描（CBCT）在三个时间点（T0：术前，T1：术后即刻，T2：术后6个月）拍摄图像。测量二维和三维增强参数，包括根尖骨高度（ABH）、内窦骨增重（ESBG）、种植体周围骨高度（PBH）、边缘骨损失（MBL）和增强骨体积（AV）。比较了DBBM小粒径和大粒径增强参数的差异。结果T1时sav为916.76 (657.88 ~ 1243.74)mm3， T2时sav降至823.73 (583.12 ~ 1178.79)mm3，相对体积稳定性为89.8%。虽然两组在T1 （p = 0.379）和T2 （p = 0.264）时ABH差异无统计学意义，但大颗粒组的AV、ESBG和PBH均显著升高。在6个月的随访中，AV降低率(p <；大颗粒组ESBG （p = 0.022）、PBH （p = 0.004）较低。结论在6个月的随访中，LSFE同时植入种植体后的隆胸效果有所下降。采用大粒径的DBBM提高了增强稳定性。
