^aLinear mixed models: changes between D and 1 y and differences regarding the implant type (Ace/Max). ^bLinear mixed models: for every timepoint (D, 1 y) regarding the implant type (Ace/Max). ^cOne radiograph (one control implant) at 1 y was insufficient for BL measurements. ^dOne file (two control implants) including clinical measurements was missing for D.
