Title No Significant Differences in Survival Among Immediate, Early or Conventional Implant Strategies
Clinical Question Following the extraction of an anterior tooth in an adult, is there any difference in success rates between immediately loaded implants and conventionally loaded implants?
Clinical Bottom Line No significant differences in survival were reported in clinical trials comparing immediate, early, or conventional implant strategies. (See Comments on the CAT below)

(level of evidence)
#1) 19040585den Hartog/2008Patients who were treated with a single tooth implant in the esthetic zone (teeth 15–25 and teeth 35–45) with natural adjacent teeth.Meta-Analysis
Key results19 longitudinal studies (including randomized controlled trials, clinical trials, cohort-studies, and case series) were included in this systematic review. A meta-analysis showed an overall survival rate of 95.5% [95% confidence interval: (93.0-97.1)] after 1 year. No significant differences in outcome measures were reported in clinical trials comparing immediate, early or conventional implant strategies. However, important parameters as aesthetic outcome, soft-tissue aspects, and patient satisfaction were clearly under exposed.

Comments on
The Evidence
The studies included in this meta-analysis only covered 1 year. Also, esthetic outcome, soft tissue aspects, and patient satisfaction should be considered but were not analyzed.
Applicability Single tooth implant patients in the esthetic zone (teeth 15-25 and teeth 35-45) with natural adjacent teeth.

I performed a PubMed search on this question in April of 2012 and I found a more recent publication: PubMed ID: 22282730. This RCT on 106 patients finds fewer implant failures for healed sockets and adds statistically significant evidence showing more minor complications for immediate implant placement.
