A meta-analysis was performed on eleven studies that compared marginal bone loss between implants restored with the following protocols: Immediate restoration/loading; early loading; conventional loading
After adjusting for implant placement levels, no significant difference was found when comparing marginal bone loss for four scenarios:
immediate restoration/loading + delayed placement versus conventional loading + delayed placement.
immediate restoration + delayed placement versus early loading + delayed placement.
early loading + delayed placement versus conventional loading + delayed placement.
immediate loading + immediate placement versus conventional loading + immediate placement.
The timing of restoration does not have an effect on implant marginal bone loss according to this meta-analysis when comparing the clinical scenarios outlined above.
