Prosthesis failure · Patients receiving immediate single implants in fresh extraction sockets (maxillary anterior/premolar sites)
Autogenous bone graft augmentation at the immediate implant site led to lower prosthesis failure compared with no augmentation; GRADE not reported.
1 finding from 1 review
In total two implants were lost in the autogenous bone group, whereas no complications or failures occurred in the non-augmented control group; underpowered, no statistically significant difference (Chen 2005b).
