Abstract

Introduction

The present investigation compared the stability and volumetric changes of two different grafting material used for lateral window sinus floor augmentation (LWSFA).

Methods

Sixteen patients with a total 20 maxillary sinuses in need of LWSFA were included in the present study. The sinuses were grafted with either 100% anorganic bovine bone mineral (ABBM) alone (Group 1) or a mixture (0.8:1 ratio) of ABBM and mineralized cortical allograft (MCA) (Group 2). Cone beam computer tomography (CBCT) was obtained pre-operatively, and at 2-weeks, and 6-months after LWSFA to perform linear measurements including lateral window dimensions, sinus anatomy, residual bone height/thickness (RBH/RBT), and Schneiderian membrane thickness (SMT), among others. Three-dimensional segmentation analysis was used to evaluate changes of bone graft volume/height (GV/GH).

Results

A total of 10 sinuses per group were included in the analysis. No statistically significant difference was found in between groups regarding mean reduction of GV (Group 1: 14.87% ± 16.60%, Group 2: 18.06% ± 9.81%, p = 0.33). Among the linear measurements, only SMT revealed a significant increase after 2-weeks more pronounce in Group 1 (8.70 mm) when compared with Group 2 (5.70 mm) with plausible effect upon LWSFA outcomes. Sinus width showed weak positive correlation with GH reduction after 6 months.

Conclusion

This study demonstrated that both ABBM alone and ABBM + MCA represent suitable alternatives for LWSFA with adequate graft stability as they revealed similar volumetric and linear dimensional changes 6 months postoperatively.

侧窗窦底扩大术后的体积变化和移植物稳定性：一项随机临床试验。

引言：本研究比较了两种不同的移植物材料用于侧窗窦底扩大术（LWSFA）的稳定性和体积变化。方法：本研究包括16例共20个上颌窦需要进行LWSFA的患者。用100%无机牛骨矿物质（ABBM）单独移植鼻窦（第1组）或用ABBM和矿化皮质同种异体移植物（MCA）的混合物（0.8:1的比例）移植窦（第2组）。术前、LWSFA后2周和6个月进行锥束计算机断层扫描（CBCT），以进行线性测量，包括侧窗尺寸、鼻窦解剖结构、残余骨高度/厚度（RBH/RBT）和Schneiderian膜厚度（SMT）等。采用三维分割分析法评估骨移植体积/高度（GV/GH）的变化。结果：每组共有10个窦被纳入分析。两组之间GV的平均降低没有统计学上的显著差异（第1组：14.87% ± 16.60%，第2组：18.06% ± 9.81%，p = 0.33）。在线性测量中，只有SMT在第1组发音增加2周后出现显著增加（8.70 mm）与第2组（5.70 mm），对LWSFA结果有可能的影响。窦宽度与术后GH下降呈弱正相关月。结论：本研究表明，单独的ABBM和ABBM+MCA都是具有足够移植物稳定性的LWSFA的合适替代品，因为它们显示出相似的体积和线性尺寸变化6 术后数月。
