Table 6 Peri-implant bone loss after 20 years

From: Peri-implant bone-level changes in the second decade of loading with regard to the implant–abutment connection: a retrospective study on implants under systematic aftercare

Implant type n Min. bone loss Max. bone loss Median Mean sd
Tissue-level conical 14 − 0.5 4.5 1.7 1.7 1.4
Bone-level butt-joint 41 0 7.2 1.9 2.3 1.7
Bone-level conical 38 0.4 7.4 2.7 3.0 1.6
Total 93 − 0.5 7.4 2.3 2.5 1.7
