This study aimed to investigate the correlation between anatomical structures of the maxillary sinus and early implant failure (EIF) following sinus augmentation.
A retrospective cohort study conducted at a single medical centre. Individuals who underwent maxillary sinus floor augmentation for dental implant placement via the lateral approach. Preoperative imaging was evaluated for anatomical variables, including the presence of septa, alveolar antral artery, Schneiderian membrane thickness, maxillary sinus lateral wall thickness, residual alveolar bone height, and maxillary sinus shape. Univariate and multivariable analyses assessed the associations between anatomical factors and EIF. A P value <.05 was considered significant.
A total of 159 maxillary sinus floor augmentations in 143 individuals were included. The increased presence of bony septa and thicker lateral walls were significantly associated with lower odds of EIF. Smokers had significantly higher chances of EIF.
Anatomical features of the maxillary sinus, specifically the increased prevalence of bony septa and thicker lateral walls, are significantly associated with lower EIF rates following maxillary sinus augmentation.
These findings emphasize the need for comprehensive preoperative radiographic assessment beyond the traditional focus on residual alveolar bone height to enhance the predictability and success of maxillary sinus augmentation procedures.
本研究旨在调查上颌窦的解剖结构与上颌窦提升术后早期种植失败（EIF）之间的相关性。
在单一医疗中心进行一项回顾性队列研究。纳入通过外侧入路进行上颌窦底提升以植入牙种植体的个体。对术前影像进行解剖学变量评估，包括间隔的存在、牙槽窦动脉、施奈德膜厚度、上颌窦外侧壁厚度、剩余牙槽骨高度以及上颌窦形状。单因素和多因素分析评估解剖学因素与EIF之间的关联。P值<0.05被认为具有统计学意义。
共纳入143例个体的159次上颌窦底提升术。骨间隔增加和外侧壁增厚与EIF几率降低显著相关。吸烟者发生EIF的几率显著更高。
上颌窦的解剖特征，特别是骨间隔增加和外侧壁增厚，与上颌窦提升术后较低的EIF发生率显著相关。
这些发现强调，除了传统上关注剩余牙槽骨高度外，还需要进行全面的术前影像学评估，以提高上颌窦提升手术的可预测性和成功率。
