How old is old for implant therapy in terms of implant survival and marginal bone levels after 5-11 years?

The high implant survival rate (95.4%), low mean MBLevel (1.24 mm) and low frequency of maximum MBLoss  ≥ 5 mm (0.5%) observed herein after 5 to 11 years follow-up suggest that older age should not be considered as a limiting factor for implant treatment.
