Table 3 Bone height reduction rate between the tip of implant and sinus membrane.
| Groups | N | H1, mean±SD | H2, mean±SD | Mean height reduction rate*, mean±SD |
|---|---|---|---|---|
| Control | 42 | 4.04±1.57 mm | 3.35±1.54 mm | 19.10±10.28% |
| Test | 42 | 3.95±1.76 mm | 3.30±1.62 mm | 17.26±12.34% |
| P value | 0.803 | 0.882 | 0.467 | |
| H – height immediately after surgery; H – height 6 months after surgery; SD – standard deviation. * Mean height reduction rate=(H–H)/H×100%. | ||||
