Clinical Application Strategies of Maxillary Sinus Buccal Bony Window
Clinical Application Strategies of Maxillary Sinus Buccal Bony Window With Different Residual Bone Heights in Lateral Maxillary Sinus Floor Elevation
The Dental Hospital of Zhejiang University School of Medicine
60 participants
Mar 10, 2022
INTERVENTIONAL
Conditions
Summary
Through randomized controlled trials, investigators will recruit participants who need maxillary sinus floor elevation with different residual bone height, and utilize the maxillary sinus buccal bony window during the surgery. Then investigators will gather the related information of participants, collect and analyze their CBCT data, in order to help surgeons select the best operating method for different patients.
