Inclusion criteria

Inclusion criteria: 1.Patients whose vertical distance of the alveolar bone to the maxillary sinus at the planned implantation location is 3-7.5 mm according to CBCT, and it has been determined that maxillary sinus floor elevation using the alveolar crest approach is necessary for implant placement. 2. Age: Patients aged 20 to 90 years at the time of obtaining consent. 3. Patients who have received sufficient explanation to participate in this study, and who have given their own voluntary written consent based on sufficient understanding.

Exclusion criteria

Exclusion criteria: Patients who fall under any of the following will be excluded from the study. 1. Patients with severe blood disorders 2. Patients suspected of having abnormalities in calcium metabolism system organs such as kidneys or digestive organs or collagen disease 3. Patients who are considered difficult to visit for follow-up, such as those living in remote areas 4. Patients whose social or home environment restricts their ability to comply with the requirements of this study 5. Smoker 6. Patients who are pregnant or breastfeeding. 7. Patients who require a legal guardian 8. Patients receiving treatment with drugs that affect bone metabolism, such as bisphosphonates. 9. Other patients judged to be inappropriate by the research director or research co-investigator.

Primary

Measure	Time frame
Find out when ISQ>65	—

Secondary

Measure	Time frame
1) Image evaluation: amount of host bone, amount of created bone. 2) Torque value at the time of implantation. 3) ISQ: At the time of implantation, at each measurement, and at the time of final prosthesis placement. 4) Number of implants for which ISQ>65 could not be obtained by the period.	—
