| Implant Survival Population (n = 77) | ||
| Outcome | Test Group (n = 52) | Control Group (n = 25) |
| Implant loss 0–5 yra | ||
| Including explantations | 3 (6.1%) | 2 (10%) |

a0–5 year included all measurements from surgery till 5-year follow-up for ISQ, and all measurements from first postoperative visit till 5-year follow-up for soft tissue reactions.
bWhen comparing Holgers 0–1 with Holgers 2–4 statistical analysis between groups results in p = 0.048 for Holgers at 5 years and p = 0.011 for maximum Holgers 0–5 yrs.
AUC indicates area under the curve; ISQ, implant stability quotient.
