研究目的:

本研究旨在评估黏性骨块(Sticky Bone)应用于上颌窦外提升术后的成骨效果,并利用机器学习技术预测术后6个月骨量变化。通过回顾性收集患者术前临床资料、生化检验资料、病史资料、手术相关资料、术后CT影像资料及并发症记录,构建基于多维数据的机器学习预测模型,分析影响术后成骨效果的关键因素,为临床医生进行术前风险评估、个体化手术方案制定及术后管理优化提供依据。  

Objectives of Study:

This study aims to evaluate the osteogenic effect of Sticky Bone after lateral maxillary sinus floor elevation and to predict bone volume changes 6 months after surgery using machine learning techniques. By retrospectively collecting preoperative clinical data, biochemical test results, medical history, surgery-related variables, postoperative CT imaging data, and complication records, this study will construct a multidimensional machine learning prediction model to identify key factors associated with postoperative bone formation. The results are expected to provide evidence for individualized preoperative risk assessment, surgical planning, and postoperative management.
