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.
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.

| Measure | Description | Time Frame |
|---|---|---|
| ABH change | Apical bone height (ABH): Represented the grafted height at baseline and the grafted height with neo-formed bone at follow-ups. | baseline, 6 months, and 1, 2, 3, 5, 10 years after the surgery |
| ESBG change | Endo-sinus bone gain (ESBG): ESBG = ABH + implant protrusion length at baseline; ESBG represented the grafted height and neo-formed bone, and described the height difference of radiopaque area in the sinus cavity at different times. | baseline, 6 months, and 1, 2, 3, 5, 10 years after the surgery |
| RBH | Residual bone height (RBH): Only assessed at baseline | baseline |
