At 2 weeks after insertion, the mean ISQ was 60.60 ± 3.42 in group 1 and 58.25 ± 3.64 in group 2. There was a statistically signifificant difference between the two groups (P = 0.04). At 4 weeks after insertion, the mean ISQ was 70.30 ± 3.36 in group 1 and 67.15 ± 4.33 in group 2. Analysis of the data demonstrated a signifificant difference between the two groups at this time point (P = 0.014). The mean ISQ was 78.45 ± 3.36 in group 1 and 76.15 ± 2.94 in group 2 at 6 weeks afterinsertion. Assessment of the data showed a signifificant difference between group 1 and group 2 at this time point (P = 0.027) |

3.group showed statistically higher ISQ values compared to the test group (75.13 ± 5.69; and 60.90 ± 9.35 for the control and test group, respectively). This outcome might be attributed to the difference in the healing time between both groups. According to a previous study,31 ISQ values after sinus augmentation utilizing L-PRF progressively increase over time, meaning that the time for implant healing play a crucial role for increased secondary implant stability. This was confirmed in our studies because the ISQ values at loading demonstrated a significant increase in the test group compared to the initial value immediately at implant placement (60.90 ± 9.35 and 76.08 ± 5.86).T:P = 0.0014 C:P = 0.9927 |

No significant statistical difference existed in primary implant stability between the groups (P = 0.054). An improvement in implant stability was observed in the PRF group(ISQ = 71.0 ± 7.3) compared with control group(ISQ = 67.2 ± 8.2) 6 weeks after implant insertion. After 12 weeks, implant stability was further enhanced in the PRF group (ISQ = 74.5 ± 8.1) compared with control group(ISQ = 70.8 ± 8.3). |

PRF membrane group’s average ISQ ranged from 38.5 to 61 (mean = 43.06,SD = 7.41) at baseline and ranged 66.5–71.5(mean = 69.12,SD = 1.78) at second-stage surgery. Collagen membrane group’s average ISQ ranged from 34.5 to 40.5 (mean = 41.68, SD = 7.2) at baseline and ranged 65.5–71.5(mean = 68.56,SD = 1.52) at second-stage surgery. |

There was a statistically significant difference seen for values between two groups (P < 0.05) with higher ISQ values in Group 1, 59.56 ± 4.51, than Group 2, 57.12 ± 3.82 at 1 month. |
