Objectives: Mini‐implants are used for orthodontic bone anchorage. The reasons for a
potential instability or loss of the mini‐implants during treatment are multiple. Among other
factors, colonization of implants with pathogenic bacteria is discussed. Therefore, the
microflora associated with successful and failed mini‐implants has been screened. Material

Abstract
Objectives: Mini‐implants are used for orthodontic bone anchorage. The reasons for a potential instability or loss of the mini‐implants during treatment are multiple. Among other factors, colonization of implants with pathogenic bacteria is discussed. Therefore, the microflora associated with successful and failed mini‐implants has been screened.
Material and methods: A total of 76 mini‐implants collected from 25 patients were observed during regular orthodontic treatment. Bacterial samples of eight failed and – exemplarily – four successful (control) cases were subjected to a universal Bacteria‐directed real‐time quantitative polymerase chain reaction for quantification in combination with a microarray‐based identification of 20 selected species.
Results: The failure rate in the present investigation was 10.5%. The bacterial analysis did not reveal any major difference in the total amount or species composition between control and failed mini‐implants. However, Actinomyces viscosus was found in four (100%) and Campylobacter gracilis in three (75%) stable controls, whereas both species were rarely found (12.5%) in failed implants.
Conclusions: In the present study, the peri‐implant sulcus surrounding failed orthodontic mini‐implants did not show a specific aggressive bacterial flora.
