Details and patient eligibility

About

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.

Full description

Through randomized controlled trials, investigators will recruit 60 participants who need maxillary sinus floor elevation with different residual bone height (0~3mm; 3~5mm), and utilize the maxillary sinus buccal bony window during the surgery (A: ground into pieces; B: replace the bone; C: turn inward to hold up the membrane). 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.
