简要总结
The goal of this study is to investigate the clinical efficacy of different maxillary sinus floor elevation procedures based on maxillary sinus anatomy.
The main questions it aims to answer are:
- How does the anatomical morphology of maxillary sinus affect postoperative bone resorption?
- How to select the appropriate maxillary sinus floor elevation procedure based on maxillary sinus anatomy? Preoperative, immediate postoperative, and six-month postoperative CBCT images of patients undergoing translateral maxillary sinus floor elevation or hydraulic transcrestal maxillary sinus floor elevation will be measured.
