Meta-analyses of clinical studies on alternative implant materials and survival rates.
| Study/Year | Material | Marginal Bone Loss | Survival Rate (%) |
|---|---|---|---|
| Borges et al. 2020 [151] | Zirconia | 0.80 mm (95% CI: 0.60 to 1.00) at a 1-year post-loading. |
71.2% at 1 year to 100% at 7.8 years. |
| 1.01 mm (95% CI: 0.72 to 1.29) at a 2-year post-loading | |||
| Adanez et al. 2018 [152] | Zirconia | 0.89 mm (95% CI: 0.60 to 1.18) at a 1-year post-loading period. |
76% to 100% after observation periods between 1 and 7 years. |
| The mean survival rate was 95% after an observation period between 1 and 7 years (one-piece zirconia: 95%, two-piece zirconia: 94%). | |||
| Borges et al. 2020 [151] | Titanium–zirconia alloy | 0.36 ± 0.06 mm after 1 year. | 98.4% at 1 year after implant placement. |
| 0.41 ± 0.09 mm after 2 years. | 97.7% at 2 years after implant placement. |
