Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Radiographically measured gain in subantral bone height (mm), sufficient for proper implant placement, assessed by CBCT approximately 5 months after sinus floor elevation. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Histomorphometric composition of the newly formed tissue in the augmented sinus region (percentage of new bone, connective tissue, and residual graft material), assessed from bone biopsies collected at re-entry approximately 5 months after sinus floor elevation. 2. Histological, histochemical, and immunohistochemical characterization of the newly formed tissue (including osteogenesis, vascularization, and remodeling activity) based on bone biopsies approximately 5 months postoperatively. 3. Radiographically determined bone volume using CBCT images at the time of implant placement. 4. Implant survival rate one year after functional loading of the placed implants. | — |
